Diversity of common bean (Phaseolus vulgaris L., Fabaceae) landraces in parts of southern and eastern Ethiopia

Abstract

The study identified the status of landrace (farmers' variety) diversity of common bean (Phaseolus vulgaris L.) in a participatory field research conducted in selected zones southern and eastern Ethiopia. Data were collected by interviewing common bean growers, direct field observations and ethnobotanical information retrieval. Germplasm accessions (169) and voucher specimens (39) of common bean were collected at locations ranging from 1500-2500m a.s.l. These were sorted into 133(78.7%) landraces and 36(21.3%) introduced improved varieties. The highest diversity (2.34) of landraces (12) was found in Agarfa while the lowest (0.67) at Boloso Sore where only two landraces dominated the fields. The dominant landraces were ADI TIKKO, DIMA, BORA, DUME, WAJJO, ZOOLOKOMA and BUSHAY in West Hararge, Bale, Arsi, Sidama, Wolayita and Siltie, respectively. This dominance is associated with market and use values. Farmers need to be encouraged and supported by stakeholders to consciously monitor the conservation of common bean landraces for all their worth, which include use values, agroecological intensification, income generation potential, role in breeding and other domestic purposes. In addition to this, governmental and non-governmental organizations should consider the conservation of common bean landraces under both in-situ and ex-situ strategies.

On-farm management and participatory evaluation of pigeonpea (Cajanus cajan [L.] Millspaugh) diversity across the agro-ecological zones of the Republic of Benin

“…This situation may contribute to under or over-estimation of the diversity within species [40,25,41,9]. To avoid redundancies and optimize the efficient conservation and sustainable use of pigeonpea diversity, it is important to conduct morphological and molecular characterizations to avoid redundancies and establish equivalence between the local names [28,42,43].…”

Diversity and genetic potential of various morphological traits among common bean (Phaseolus vulgaris, Fabaceae) landraces

“…The materials used in this study were 24 common beans (Phaseolus vulgaris L.) landraces ( Table 1). The landraces were collected from different geographic locations of Oromia and Southern Nations, Nationalities and Peoples (SNNP) regions of Ethiopia (Bareke et al 2018).…”

“…Wide-ranging shapes of common bean seeds grown in many parts of continent occupy an important part of the diversity of agricultural crops (Ivanovska et al 2012). The food, agricultural and ecological values of common bean (Phaseolus vulgaris L.) are tremendous (Bareke et al 2018). It is one of the most important and widely distributed pulses that have the broadest range of genetic resources and its grain used to direct human consumption (Singh 1999;Sperotto and Ricachenevsky 2017).…”

“…This diversity reflects the wide range of ecological and human environments under which the crop has evolved over a long period of time (Singh et al 1991;Francesc et al 2017). Common bean is an important legume crop in Ethiopia, a country in which the legume family holds the highest number of species (about 10% of the flora) containing many leguminous crop species known for rich inter and intraspecific diversity (Bareke et al 2018). Among the grain legumes cultivated in Ethiopia, common beans are regarded as the most important crop for food security and wealth creation (Asfaw and Blair 2014).…”

“…In Ethiopia, there is considerable potential of common bean genetic diversity which needs renewed conservation efforts for the region (Asfaw et al 2009;Bareke et al 2018). For conservation and breeding priorities landraces characterization is very important.…”
