ABSTRACT

Common bean (Phaseolus vulagris L) is the second most important source of human dietary proteins and the third most important source of calories. Common bean seeds contain 20-25% proteins, much of which is made up of the storage Protein phaseolin. A field experiment was conducted on farmer’s field of Gimbo district Kafa zones in the Southwest Ethiopia region (SWER). The objective of the study was to select the best-performing common bean varieties to increase productivity and production of common beans in the target areas. The treatments involved were nine improved varieties of common bean: Ibadu, Gegeba, Tatu, Omo-95, Remeda, Nasir, Tafache, SER-119, SER-125, and Local. The experiment was carried out using a randomized complete block design (RCBD) with three replications at Gimbo district in 2021 and 2022 under rain fed condition. ANOVA revealed significant differences among the varieties (P< 0.001) for days to flowering, days to maturity, plant height, the number of pods per plant, the number of seed per pod and grain yield.  However, the variety x year’s interaction was no significant for all traits which implies the durability of varieties in each year. Among the tasted varieties Gegeba (77.66 days) was early maturing type. Variety, Tatu was observed as dwarf type (37.46 cm tall) which used for logging sensitive areas. The highest grain yield quintal per hectare was harvested from variety SER-119 (32.25qtl/ha), followed by varieties, Ibado (30.69 qtl/ha), Nasir (30.59 qtl/ha) and SER-125 (30.09 qtl/ha). Therefore, varieties SER-119, Ibado, Nasir and SER-125 was recommend as promising varieties for the study areas and areas with similar agro ecologies.
