Agro-Morphological Variability Assessment of Common Bean (Phaseolus vulgaris L.) Genotypes in High Hill Jumla, Nepal

Common bean (Phaseolus vulgaris L.) is the most important leguminous crop widely grown from Terai to high hills of Nepal covering 10,529 hectare land producing 15550 mt with the productivity of 1477 kgha-1 and Jumla occupies almost 21% of the total bean cultivated area of the country. For the experiment, twelve genotypes of common bean were collected from different locations of Nepal. The experiment was conducted at Agricultural Research Station Vijayanagar, Jumla Nepal from July, 2016 to October, 2016 in Randomized Complete Block Design with three replications and twelve treatments. Different agro-morphological characters were observed and wide variability was recorded in growth habit, flower color, seed color, seed shape, seed length (0.76-1.7cm), pod color, pod length(9.1-14.3 cm), plant height (57.1-116.5 cm), days to flowering (38-52 days) and maturity (74-90 days), number of pods plant-1 (9-22 seeds), number of seeds pod-1 (4-8 pods), hundred grain weight (18.3-54.7gm) and yield (2339-4164KgHa-1). Significant differences were found among genotypes for days to flowering, pod length, no of seeds pod-1 and yield hectare-1.The coefficients of determination illustrate the positive and significant association of grain yield hectare-1 with number of seeds pods-1, therefore these traits should be considered for genetic improvement through breeding.
