“…Indeed, the regions of Mayo Kebbi Est and Ouest, present a significant diversity per village. Regionally, the average number of landraces in this part of southern Chad is almost similar to that of three regions located in the southwestern parts of Ethiopia (Alemu et al, 2019). However, the average of landrace collected per village which is 2.70 is low compared to 4.29 reported by Gapili et al (2020).…”

“…In terms of treatments for therapeutic uses, in a study conducted in Togo, Agbodan et al (2020) identified local varieties of cowpea that help to fight against malnutrition because they have remarkable antioxidant potential compared to the introduced varieties. In Ethiopia, the green leaves and grains of cowpea are used in the treatment of liver disease, gastritis and malaria (Alemu, 2019).…”

In Chad, cowpea (Vigna unguiculata (L.) Walp.), is increasingly becoming a cash crop. The objective of this work is to assess the varietal diversity, analyze the traditional management of landraces and the production systems of cowpea in southern part of Chad. An inventory and an ethnobotanical survey was conducted through a participatory approach in 17 villages corresponding to two agro ecological zones. Thirty-four vernacular names and 45 landraces are inventoried. On average, 2 names are assigned per village. The number of landraces varies from 4 to 13 with an average of 9.00 per region and 2.70 per village. The highest diversity is observed in Mayo Kebbi. Sixteen morphotypes have been identified and their distribution varies according to the agro ecological zones. Productivity (31.10 %), taste (25.92 %) and grain size (18.34 %) are the farmer main preferred criteria. Farmers use leaves (47 %), pods (29.50 %) and seeds (14.75 %) to identify landraces. Cowpea cultivation is practiced on small areas and in intercropping system (78.60 %). Conservation of seeds (36.07 %), low fertility of the soils (27.85 %) and drought (17.77 %) were the main production constraints. Cowpea is stored mainly in traditional granaries (34.96 %) and on racks (22.93 %). For seeds treatment, farmers use mainly traditional means (32.37 %) and chemical products (6.67 %). Several cowpea-based dishes are identified. Cowpea has also therapeutic virtues. To improve cowpea production, appropriate actions must be considered against the constraints inventoried. The interesting landraces should also be used in a breeding program. Int. J. Appl. Sci. Biotechnol. Vol 9(3): 176-186.

“…Genetic diversity is a prerequisite for the identification of superior genotypes, which may be recommended for direct release as commercial cultivars for wider production, but also for the identification of desirable parents to use as source materials in breeding programs (Rajaravindran and Natarajan, 2011). Ethiopia is believed to have considerable genetic diversity for cowpea both at phenotypic and genotypic levels (Belayneh et al, 2016;Mulugeta et al, 2016;Sisay et al, 2019;Tesfaye et al, 2019). Apart from genetic diversity for the regular morpho-agronomic traits at phenotypic level and for molecular diversity at genotypic level, information on the magnitude and pattern of phenotypic diversity for immature pod traits in Ethiopian landrace collections is scanty.…”

This study was undertaken to evaluate the extent and pattern of genetic diversity for immature pod traits in Ethiopia cowpea landrace collections. Eighty one landraces and improved cultivars were tested in a 9 x 9 simple lattice design. Analysis of variance revealed highly significant (P<0.01) or significant (p<0.05) differences among the genotypes for all traits. The first four principal components were able to explain 81% of variation for quantitative traits and 76% for qualitative traits. The genotypes were grouped into three distinct clusters, the first, second and third clusters with 60, 15 and 25% of the genotypes in that order. The landraces were distributed all over the clusters while the improved cultivars were absent in the second cluster. Shannon-Weaver diversity indices also showed existence of adequate genetic variability among the genotypes for qualitative traits. Shannon-Weaver diversity indices ranged from the lowest of 0.50 for pod curvature to the highest of 0.99 for pod shape. The study clearly showed that, even if the genotypes were classified into a few cluster, there was adequate divergence among the clusters showing existence of considerable genetic variability for immature pod traits for exploitation in future breeding for better green pod yield and quality in cowpea.

“…More recently, several ethnobotanical studies have documented the continued use of traditional legume varieties by farmers (e.g. [35,36]), but have not investigated their current status in a systematic way. To date, there has been no nationwide survey to document farmers’ knowledge and use of grain legume varieties.…”

Inter- and intraspecific diversity of food legumes among households and communities in Ethiopia

et al. 2019

Smallholders throughout sub-Saharan Africa produce legume crops as sources of food, fodder, and cash income, as well as to improve soil fertility. Ethiopian farmers have developed diverse legume varieties that enable adaptation to changing agroecological and sociocultural conditions. However, over the past several decades, as farm sizes declined and extension services promoted new varieties developed by plant breeders, changes in legume diversity have not been monitored. Based on interviews with smallholder farmers (n = 1296), we investigated the status of inter- and intraspecific legume diversity in major production areas of Ethiopia for five food legumes: common bean (Phaseolus vulgaris L.), field pea (Pisum sativum L.), faba bean (Vicia faba L.), groundnut (Arachis hypogaea L.) and fenugreek (Trigonella foenum-graecum L.). Legume species richness increased with altitude, relative household wealth, and land area planted to legumes. The highest numbers of varieties were found for common bean, followed by field pea, faba bean, groundnut and fenugreek. The average number of varieties planted per household was low (ranging from 1 to 2) and often much lower than the number reported in the same community or zone, which ranged from 2 to 18. For three out of the five species, the number of varieties significantly increased with total land area planted to legumes. Most varieties were rare, planted by less than 1/3 of farmers; however, informants accurately named varieties planted by others in the same community, demonstrating awareness of legume diversity at the community level. Given that the ability to plant multiple legume varieties is limited by land size, policies need to strengthen community-level conservation based on the diverse interests and needs of individual households.
