Tropical countries face considerable economic losses due to mosquito-borne diseases which can be effectively combatted using plant-based mosquito repellents. Therefore, using a questionnaire survey, we selected the 25 top-ranked common but underutilized aromatic plants with mosquito repellent ability in Sri Lanka to investigate the rural sector's willingness to cultivate and supply them. , , , , , and were the common species thus identified. The willingness to cultivate and supply aromatic plants with mosquito repellent ability varied between 88% and 60%. The Chi-squared test indicated a significant association between gender and willingness to cultivate and supply these plants. Men had a higher willingness (82%). Persons formally educated up to elementary school level had the highest willingness (85%). The willingness from households with many non-income-generating members was 100%. The random forest model developed in this study identifies farmers' willingness to cultivate and supply aromatic plants with mosquito repellent properties. It was trained using an upsampling strategy. Our findings aid in understanding the scenarios involved with introducing, cultivating, and supplying aromatic plants.

Non-timber forest products (NTFPs) are known to provide livelihoods for forest-based communities across the world. While ensuring the sustainability of NTFP harvests is a key challenge, optimizing the production of NTFPs through appropriate silvicultural practices is also critical for forest-based economies. In Central India, the suitability of fire or pruning practices for enhancing the production of leaves of the tendu tree () has been much debated. While villagers commonly adopt annual litter fires, the state Forest Department urges leaf collectors to adopt the more labor-intensive practice of pruning. On the other hand, conservationists recommend completely hands-off management (no fire or pruning). In this study, we compared leaf production from the competing practices of litter fire, pruning, pruning-with-fire, and hands-off management, that are experimented with in community-managed forests. We checked for confounding factors such as tree canopy cover, presence of tendu trees, and inherent differences in forest type. We conducted the study during the pre-harvest season from March to May 2020 in villages in the northern Gadchiroli district of Maharashtra, India. We found that pruning and pruning-with-fire lead to higher root sprout production and, in turn, higher leaf production per unit area when compared to litter fire and the control (no pruning or fire). Fire alone led to a negative impact on leaf production. Implementing pruning instead of litter fire, however, comes with labor costs. Its adoption is therefore linked with the institutional arrangements for tendu management and marketing that shape community perception of costs. गौण वन उत्पादने जगभरातील वन-आधारित समुदायांसाठी उपजीविका म्हणून महत्त्वाची आहेत. त्यांच्या शाश्वत उपलब्धतेसाठी तसेच त्यांच्यावर अवलंबून आजीविकांच्या दृष्टीने वन उपजाच्या नियोजन पद्धतींचा वनवृक्षशास्त्राच्या दृष्टीने अभ्यास होणे गरजेचे आहे. मध्य भारतातील वन-आधारित समुदाय अनेक वर्ष तेंदू वृक्षाच्या पानांना (म्हणजे बिडी-पत्त्याला) निरनिराळ्या पद्धतीने संकलित करीत आहेत व त्याकरिता निरनिराळ्या पद्धतीने नियोजन करीत आहेत. झाडाची झुडपी वाढ करून, पाने हाता जवळ वाढवणे हा त्यातील मुख्य उद्देश आहे. यामध्ये झाडाच्या रोपांची मुळाशी छाटणी करणे (खुट/बेल कटाई) किंवा, जंगलातील पाचोळा पेटवणे, किंवा या दोन्ही पद्धती एकत्रित वापरणे ('छाटणी-व-आग') अशा पद्धतींचा समावेश आहे. अलीकडे काही लोक तेंदू संवर्धनासाठी झाडाची विना-नियोजन वाढ होऊ देतात (म्हणजे विना आग आणि विना खुट कटाईने). यातील कोणत्या पद्धतीने प्रती हेक्टरी सर्वात जास्त तेंदू पाने तयार होतात याचा अभ्यास आम्ही केला. यासाठी आम्ही उत्तर गडचिरोली, महाराष्ट्र येथील काही गावांच्या सामुहिक वन क्षेत्रात मार्च ते मे २०२० मध्ये वेगवेगळ्या नियोजन पद्धतीमध्ये होणाऱ्या तेंदूपत्ता उत्पन्नाचा पद्धतशीर अभ्यास केला. एकूण आम्हाला असे दिसले की, आग वापरण्यापेक्षा तेंदूच्या रोपांची मुळाशी केलेली छाटणी व 'छाटणी-व-आग' या पद्धती अधिक पानांचे उत्पन्न देतात. आम्ही पाहिले की स्थानिक जंगल प्रकार, त्याची दाटी, व तेंदू वृक्षाची निकटता या निकषांमुळे पानांच्या उत्पन्नात नियोजन पद्धतीपेक्षा जास्त परिणाम होत नाही. परंतु यातील कोणतीही पद्धत वापरताना व वन-आधारित उपजीविका सांभाळत, तसेच सामुहिक वन नियोजन करताना काही व्यावहारिक अडचणी आहेत. त्यांचावरही आम्ही या अभ्यासात विचार केला आहे.

Bioassay screening of plant extracts can identify unique lead compounds for drug development, but the "hit rate" from random screening is very low. Targeted screening of medicinal plants has been repeatedly reported to increase the percentage of samples displaying bioactivity. Contrarily, Maranz (2012) suggested that African antimalarial plants were unsuitable sources of antimalarial drugs because high prevalence of malaria would result in rapid evolution of resistance to active compounds that directly targeted the parasite. As malaria is highly prevalent in much of Madagascar, it was of interest to determine whether Malagasy antimalarial plants would outperform randomly selected plants in conventional antimalarial assays being conducted as part of a discovery program. Of 1294 plant samples screened for antimalarial activity, 39.6% had an IC <50 μg/ml and 21.1% had an IC <20 μg/ml (the minimum to qualify as a first-pass "hit"). Ethnobotanical uses were coded at both the generic and the species level, as neither samples nor use reports in literature were always identifiable to species level. The 526 samples belonging to genera having reported uses for malaria were slightly more likely than average to display activity (44.3% with IC <50 μg/ml, p < .01; 23.2% with IC <20 μg/ml). Of these, 67 samples from individual species with documented use were still more likely to be modestly active (49.3% with IC <50 μg/ml), yet less likely to be highly active (17.9% with IC <20 μg/ml). Thus, in this specific context, ethnobotanically directed screening would not have substantially improved screening efficiency, and would have missed most of the potential hits.

Our research involves of how Paraguayan migrants who are living in Misiones, Argentina, manage medicinal plants in home gardens, and how this practice can be related to the landscape. We examine the relationship between the richness of home garden medicinal plants and landscape variables (e.g., distance to the forest) by applying PLS analysis, which combines principal component analysis with linear regression. We surveyed 60 home gardens localized in a rural area, and we characterized the surrounding landscape with geospatial tools. Paraguayans' home gardens are extremely diverse sites (total of 136 medicinal species), where both native (82) and introduced species (50) are managed. People who live close to the native forest or mixed use areas (e.g., farms, secondary vegetation) tend to possess less native plants in their gardens because they are available nearby. While gardeners, who live in proximity to tree crops (e.g., pine plantations), have reduced access to wild medicinal resources; therefore, their effort is concentrated on maintaining native plants. These results reflect a relationship between accessibility to medicinal plants in the landscape and the management practices in the home gardens, a neglected driver in explaining the richness and composition of the medicinal plants in home gardens so far. Thus, we contributed evidence in support of the environmental scarcity compensation hypothesis. Finally, our study supports the idea that home gardens appear to function as a springboard for plant domestication.

This paper explores the importance of elements of the natural world, and particularly plants, among people of different religious affiliations in western Africa Plants play an overriding role in African folk religions, which in turn are closely associated with health practices and influence management decisions concerning natural resources. In spite of the extensive literature documenting ritual plant use, the cultural importance of plants in this context has not been systematically assessed. Our objective was to see whether the importance of plants was reflected in people's conceptions of (i.e., Christianity, Islam) and religions (i.e., Vodoun and Bwiti) in Benin (West Africa) and Gabon (Central Africa). By performing a cultural domain analysis (CDA) with 96 individuals, we found that, regardless of the religious affiliation of informants, plants and other elements of the natural world were more present in people's notions of folk religions than in global religions. We conclude by reflecting on the potentials and limitations of the data presented here as a starting point to explore the topic of cultural keystone species.

Nigeria is the world's largest cassava producer, hosting a diverse array of cassava farmers and processors. Cassava breeding programs prioritize "common denominator" traits in setting breeding agendas, to impact the largest possible number of people through improved varieties. This approach has been successful, but cassava adoption rates are less than expected, with room for improvement by integrating traits in demand by farmers and processors. This paper aims to inform breeding priority setting, by examining trait and varietal preferences of men and women cassava farmer/processors. Men and women in eight communities in Southwest and Southeast Nigeria were consulted using mixed methods. Women and men had significantly different patterns of cassava use in the Southwest. Fifty-five variety names were recorded from the communities demonstrating high genetic diversity maintained by growers, especially in the Southeast. High yield, early maturity, and root size were most important traits across both regions, while traits women and men preferred followed gender roles: women prioritized product quality/cooking traits, while men placed higher priority on agronomic traits. Trait preference patterns differed significantly between the Southeast and Southwest, and showed differentiation based on gender. Patterns of access to stem sources were determined more by region and religion than gender.

Approximately 80% of the African population uses traditional plants to deal with health problems, basically because of their easy accessibility and affordability. This study was carried out to document indigenous knowledge of medicinal plants used by traditional healers and elders in the treatment of reproductive health care in the Bamboutos Division of the West Region in Cameroon, Central Africa. The research methods used included semi-structured interviews and participative field observations. For the interviews, 70 knowledgeable respondents (40 traditional healers and 30 elders) were selected via purposive sampling. Voucher specimens were collected with the help of respondents, processed into the Cameroon National Herbarium in Yaoundé following standard methods, identified with the help of pertinent floras and taxonomic experts, and submitted to Department of Botany at the University of Dschang. Descriptive statistics were used to analyze and summarize ethnobotanical information obtained. Informant consensus factors (ICF) were used to elucidate the agreement among informants on the species to be used in the treatment within a category of illness. The results showed that a total of 70 plant species from 37 families (mostly of the Asteraceae [8 species], Euphorbiaceae [7], and Acanthaceae and Bignoniaceae [4 each]) are used in the treatment of 27 reproductive ailments, with the highest number of species (37) being used against venereal diseases, followed by female (29) and male infertility (21), respectively. Leaves (47.3%) were the most commonly harvested plant parts and the most common growth forms harvested were the herbs (45.7%), followed by shrubs (30%). Sixty percent of plant material was obtained from the wild ecosystems. Herbal remedies were mostly prepared in the form of decoction (66.2%) and were taken mainly orally. Informant consensus about usages of medicinal plants ranged from 0.5 to 1.0 with an average value of 0.91. It can be concluded that medicinal plants have played and will continue to play major roles in the management of reproductive healthcare in the study area.

Maintaining cultural identity and preference to treat cultural bound ailments with herbal medicine are motivations for migrants to continue using medicinal plants from their home country after moving to Europe and the USA. As it is generally easier to import exotic food than herbal medicine, migrants often shift to using species that double as food and medicine. This paper focuses on the trade in African medicinal plants in a Congolese neighborhood in Brussels (Belgium). What African medicinal plants are sold in Matonge, where do they come from, and to which extent are they food medicines? Does vendor ethnicity influence the diversity of the herbal medicine sold? We hypothesized that most medicinal plants, traders, and clients in Matonge were of Congolese origin, most plants used medicinally were mainly food crops and that culture-bound illnesses played a prominent role in medicinal plant use. We carried out a market survey in 2014 that involved an inventory of medicinal plants in 19 shops and interviews with 10 clients of African descent, voucher collection and data gathering on vernacular names and uses. We encountered 83 medicinal plant species, of which 71% was primarily used for food. The shredded leaves of Welw., Crantz, and (L.) Lam were among the most frequently sold vegetables with medicinal uses. Cola nuts, shea butter, (L.) Burm.f., and (Hook.f.). Skeels were the main non-food medicines sold. Women's health, aphrodisiacs, and rituals were the most important medicinal applications, but culture-bound ailments did not entirely dominate the plant uses. While most clients in Matonge were Congolese, most vendors and plant species were not. The Pakistanis dominated the food trade, and typical Congolese plants were sometimes replaced by West African species, creating confusion in vernacular names. African-managed shops had significantly more species of medicinal plants in stock than shops managed by Pakistanis. Almost all non-food herbal medicine was sold by Africans. Apart from informal shops, non-food herbal medicine was also sold from private homes and by ambulant vendors, probably to reduce costs and escape taxes and control by the authorities. We expect that in the future, increasing rent, strict regulations, and decreasing investments by the Congolese community will force the medicinal plant trade in Matonge to go even more underground.

. Syria is the world's second-largest importer of the dried leaves of A.St.-Hil., commonly known as yerba maté. The unique story of yerba maté in the Syrian beverage culture started at the beginning of the twentieth century when Syrian migrants returning from South America brought the beverage with them. The overall aim of our study is to understand yerba maté use among Syrians and its role as an essential part of the Syrian beverage culture. We compare yerba maté consumption on spatial, gender, and religious bases through semi-structured interviews with 50 respondents, with equal participation among genders, place of residence, and cultural-religious groups (Sunni, Alawite, Christian, Druze, and Ismaili). We found that the Alawite and Druze groups have the highest yerba maté consumption, and that men drink more than women. Yerba maté was the most preferred stimulant drink among participants, followed by coffee and tea, respectively. Interviews reveal social and cultural factors, perceived addiction, perceived pleasure, and perceived health properties as the drivers behind yerba maté consumption in Syria.

Immigrants from the Dominican Republic (DR) and Haiti are among the top foreign-born communities in New York City (NYC). As people migrate to new countries, they bring their ethnomedical beliefs and practices, and adapt their plant pharmacopoeias. Haiti and the DR share a flora on the island of Hispaniola. In NYC, the flora is limited to what is available in the city. We selected plants for future laboratory research based on ethnobotanical data from two surveys among Dominicans in the DR and NYC, and a Haitian literature review. In both Dominican datasets, gynecological infections were the top women's health condition treated with plants. We identified 10 species for this purpose reported by Dominicans that are also known medicines in Haitian culture, although not yet documented for women's health. Plants for gynecological infections potentially cause dysbiosis of the vaginal microbiota, and may increase rather than prevent disease. There is a public health need to assess traditional medicines for their ability to inhibit pathogenic bacteria, while causing minimal disruption to the vaginal flora. Several species are known antibacterials but remain to be tested for their efficacy. These results also provide a foundation for a planned ethnobotanical survey among NYC Haitian women.

French Guiana is an overseas French department in South America at the margin of the Amazon basin. Its population is characterized by an important number of cultural groups. Many inhabitants originate from the Caribbean (mostly Saint Lucia, Martinique, Guadeloupe, Haiti, and the Dominican Republic). The objectives of this study were to present an overview of the main uses of plants among the Caribbean populations in French Guiana, and how they contribute to the dynamics of plant-based practices, in order to provide insights into ethnobotanical convergences, divergences, and hybridizations (such as the importation of new species and associated practices, and the adoption of Amazonian species by Caribbean people). Interviews and botanical voucher collections were conducted throughout the coastal area of French Guiana. Sixteen Saint Lucian, nineteen Haitian, eighteen French Caribbean, and twelve Dominican informants were interviewed during the fieldwork. Altogether they use 212 botanical species. Some plants have recently been imported directly from the Caribbean, while adaptations have also taken place: some species that do not exist locally are abandoned while Amazonian species are integrated to form hybrid pharmacopoeias. The phytotherapies of these communities in French Guiana are still conserved as consistent sets of knowledge, although they tend to blend through an ongoing process of hybridization.

Erosion of ethnobotanical knowledge in indigenous communities has been reported increasingly in recent decades. This study quantitatively and qualitatively analyzed the variation of ethnobotanical knowledge in communities of the high Mixtec subregion. We interviewed 64 Mixtec about edible and medicinal plants. We evaluated the knowledge (names and knowledge of use) and the active application of the use among people of different ages, gender, education level, migrants, and non-migrants. In general, increasing age, female gender, decreasing formal education, and non-migration are positively correlated with the knowledge and use of plants. The most alarming finding concerns the knowledge of the Mixtec names of plant-people under 30 years old no longer know them. We envision a process of transition and adaptation of the knowledge and uses of plants, but inevitably enormous ethnobotanical knowledge is quickly disappearing along with the Mixtec language. La erosión del conocimiento etnobotánico en las comunidades indígenas se ha informado cada vez más en las últimas décadas. Este estudio analizó cuantitativa y cualitativamente la variación del conocimiento etnobotánico en comunidades de la subregión Mixteca alta. Entrevistamos a 64 mixtecos sobre plantas comestibles y medicinales. Evaluamos el conocimiento (nombres y conocimiento de uso) y la aplicación activa del uso entre personas de diferentes edades, género, nivel educativo, migrantes y no migrantes. En general, el aumento de la edad, el género femenino, la baja educación formal y la no migración se correlacionan positivamente con el conocimiento y uso de las plantas. El hallazgo más alarmante se refiere al conocimiento de los nombres mixtecos de las plantas: las personas menores de 30 años ya no los conocen. Visualizamos un proceso de transición y adaptación del conocimiento y usos de las plantas, pero inevitablemente un enorme conocimiento etnobotánico está desapareciendo rápidamente junto con el idioma mixteco.

Wild-foraged mushrooms represent a natural resource that provides economic value to foragers through both market and nonmarket recreational channels. Despite the importance of non-timber forest resources for sustainable management of forestlands, little attention has been paid to forages for wild mushrooms, they choose to forage, they go, and is generated. This report draws upon survey data from 78 foragers who are certified to sell their mushrooms and 85 noncertified foraging enthusiasts. Its goal is to understand foraging patterns and values for morels ( spp.) in the State of Michigan (USA). Most foragers spend fewer than 10 days each year foraging, and those who sell their morels are most likely to sell to local restaurants, pubs and bars, and informally to their friends. Certified foragers who choose to sell their morels sell for an average price of $36 per pound ($36/lb) for fresh black or yellow morels. Costs to supply fresh morels ranged widely among the 16 certified sellers who reported full cost details; over 70% of morels were supplied at costs below $30/lb, but some certified sellers incurred costs in the hundreds of dollars per pound. Recreational morel gatherers paid $43 to $335 per trip of foraging morels, with a median value of $93 per trip. Morel foragers also search for other mushrooms with oyster mushrooms ( spp.), chanterelles ( spp), hen-of the-woods (), and chicken-of-the-woods ( spp) being the most popular.

The greatest global challenge is to ensure that all people have access to adequate and nutritious food. Wild edible plants, particularly those that provide substitutes for staple foods, can play a key role in enhancing food security and maintaining a balanced diet in rural communities. We used ethnobotanical methods to investigate traditional knowledge on , a substitute staple food plant of the Dulong people in Northwest Yunnan, China. The chemical composition, morphological properties, functional, and pasting properties of starch were evaluated. We used MaxEnt modeling to predict the potential geographical distribution of in Asia. Results revealed that is a vital starch species with cultural significance in the Dulong community. There are large areas suitable for in southern China, northern Myanmar, southwestern India, eastern Vietnam, and other places. As a potential starch crop, could substantially contribute to local food security and bring economic benefit. In the future, it is necessary to study the breeding and cultivation of , as well as the processing and development of starch, to solve long-term and hidden hunger in rural areas.

The use of herbarium specimens as vouchers to support ethnobotanical surveys is well established. However, herbaria may be underutilized resources for ethnobotanical research that depends on the analysis of large datasets compiled across multiple sites. Here, we compare two medicinal use datasets, one sourced from published papers and the other from online herbaria to determine whether herbarium and published data are comparable and to what extent herbarium specimens add new data and fill gaps in our knowledge of geographical extent of plant use. Using Brazilian legumes as a case study, we compiled 1400 use reports from 105 publications and 15 Brazilian herbaria. Of the 319 species in 107 genera with cited medicinal uses, 165 (51%) were recorded only in the literature and 55 (17%) only on herbarium labels. Mode of application, plant part used, or therapeutic use was less often documented by herbarium specimen labels (17% with information) than publications (70%). However, medicinal use of 21 of the 128 species known from only one report in the literature was substantiated from independently collected herbarium specimens, and 58 new therapeutic applications, 25 new plant parts, and 16 new modes of application were added for species known from the literature. Thus, when literature reports are few or information-poor, herbarium data can both validate and augment these reports. Herbarium data can also provide insights into the history and geographical extent of use that are not captured in publications.

Global emergencies such as biodiversity loss and climate crisis urge us to identify and mainstream crop genetic resources in complex indigenous farming systems to understand their role as genetic reservoirs and identify synergies in productive landscapes between development, conservation, and food security. We aimed to characterize the inter- and intraspecific diversity of food plants of the (or Huastec) in Mexico and their distribution within and between the different land-use systems along a tropical altitudinal gradient. farmers manage a highly diverse and dynamic food biota in swidden maize fields, agroforestry systems, and home gardens. Even with a small sample size, our study provides a complete analysis of the food crop diversity in the research area. The cultivate a high number of 347 registered species and variants, most of them at medium altitude. Intraspecific diversity dominates (69%). All land-use systems of the agroecosystem complex serve as a specific pool for plant genetic resources, and there is a low similarity between and within systems and localities, especially at the intraspecific level. The proportion of rare and unique food plants is high. We recommend an agroecosystem approach and prioritization for conservation as well as other efforts related to the in situ crop genetic capital.

Childhood and adolescence are important life stages for the acquisition of knowledge about non-timber forest products (NTFPs). We show at which stage in life traditional plant knowledge is learned and analyze whether cross-cultural ethnobotanical knowledge transmission takes place. We evaluate whether the degree of forest dependency influences ethnobotanical knowledge by comparing two indigenous communities in Suriname. Traditional knowledge was documented and vouchers collected during forest walks with adult informants. Questionnaires were completed by 74 schoolchildren (age 4 to 14) to capture their knowledge of names and uses of nine important NTFPs. We tested for knowledge differences by ethnicity and NTFP categories. Local names for NTFPs were analyzed to determine cross-cultural transmission of ethnobotanical knowledge. Children from the forest-dependent Trio community ( = 23) possessed similar knowledge of NTFPs as their more urbanized peers from Apoera ( = 51). NTFP uses were acquired at an earlier age than plant names. Food and commercial NTFP uses were better known than medicinal plant uses. Cross-cultural transfer of knowledge occurred between the two communities. NTFP knowledge of children appeared to be influenced more by the time they spent within the forest, either walking to school or walking to agricultural plots, than by the level of forest dependency or acculturation.

This paper emphasizes the cultural value of plants in Nunatsiavut (Labrador, Canada), a self-governing Inuit region in the Subarctic. Via interviews with community members, we describe the links between plant usage and culture to understand the direct ways that plants are utilized for food, construction, gardening, and medicine, and to then link these uses to deeper cultural significance among three communities in Nunatsiavut (Hopedale, Postville, and Rigolet). Many plants were common amongst communities with a total of 66 taxa identified. About 75% of taxa were reported in at least two communities, corresponding to 95% of all responses. Edible plants were the most common reported usage, with emphasis on berry-producing taxa such as blueberry shrubs. Our study shows that a diversity of plants (i) support cultural activities; (ii) act as markers for historical events; (iii) highlight intergenerational exchange and valuing of plant knowledge; (iv) express the deep awareness that people have for their local environment; and (v) a medium for the expression of traditional values. The similarities in the plant responses among the communities suggest a shared body of plant knowledge. Our study supports the great cultural importance of plants in northern communities.

Contemporary germplasm conservation studies largely focus on and management of diversity within centers of genetic diversity. Transnational migrants who transport and introduce landraces to new locations may catalyze a third type of conservation that combines both approaches. Resulting populations may support reduced diversity as a result of evolutionary forces such as genetic drift, selection, and gene flow, yet they may also be more diverse as a result of multiple introductions, selective breeding and cross pollination among multiple introduced varietals. In this study, we measured the amount and structure of maize molecular genetic diversity in samples collected from home gardens and community gardens maintained by immigrant farmers in Southern California. We used the same markers to measure the genetic diversity and structure of commercially available maize varieties and compared our data to previously reported genetic diversity statistics of Mesoamerican landraces. Our results reveal that transnational dispersal creates an opportunity for the maintenance of maize genetic diversity beyond its recognized centers of diversity.

Multiplying onion ( L. Aggregatum-Group), commonly known as shallot or potato onion, has a long tradition of cultivation in Fennoscandian home gardens. During the last decades, more than 80 accessions, maintained as vegetatively propagated clones, have been gathered from home gardens in all Fennoscandian countries. A genetic analysis showed regional patterns of accessions belonging to the same genetic group. However, accessions belonging to the same genetic group could originate in any of the countries. These results suggested both short- and long-distance exchange of set onions, which was confirmed by several survey responses. Some of the most common genetic groups also resembled different modern varieties. The morphological characterization illustrated that most characters were strongly influenced by environment and set onion properties. The only reliably scorable trait was bulb skin color. Neither our morphological nor genetic results support a division between potato onions and shallots. Instead, naming seems to follow linguistic traditions. An ethnobotanical survey tells of the Fennoscandian multiplying onions as being a crop with reliable harvest, excellent storage ability, and good taste. An increased cultivation of this material on both household and commercial scale should be possible.
