Participatory variety selection of common bean (Phaseolus vulgaris L.) genotypes in the major bean producing areas of Ethiopia

Abstract

This study was conducted to identify suitable parental genotypes for breeding for resistance to bruchid and to identify the farmers’ preferred traits in common bean. For this study, 144 diverse common bean genotypes were planted in an alpha lattice design, with 3 replications at 3 locations. Participatory variety selection was done using 20 farmers at each location. Farmers identified a number of criteria for selecting suitable varieties. Yield and yield-related traits were ranked as the most important selection criteria by all farmers at all locations. However, women ranked culinary traits as the top criteria, while men were more interested in marketable traits. From the 144 genotypes, farmers selected the 10 best genotypes in all the locations. The majority of the genotypes selected at Melkassa and Alemetena were small white-seeded released varieties and breeding lines. However, all the genotypes selected at Arsi Negele were predominantly landraces of small red-seeded beans. Traits such as earliness and resistance to storage insect were important in Melkassa and Alme tena but received less attention in Arsi Negele. The integration of the farmers’ selection preferences with the breeders’ criteria can improve the efficiency of plant breeding by developing crop varieties that better fit the specific needs of the farmers.
