Abstract:
Stability was studied for seed yield and their component characters in fifty five genotypes of cluster bean under four environmental conditions during Summer and Kharif 2014 at two locations (Akola and Amravati). The variance due to genotype × environment (linear) was found to be highly significant against pooled deviation for six traits viz., internodal length, number of dry pod cluster^-1, days to first picking of dry pod, length of dry pod, width of dry pod and seed to husk ratio and the non linear component (pooled deviation) was also highly significant for all the traits except internodal length, length of dry pod and width of dry pod. The environment + (genotypes X environment) was highly significant for all the characters except plant spread and number of dry pods cluster plant^-1 against pooled deviation indicating distinct nature of environments and the effects due to environments (linear) was highly significant for all the characters. Based on stability parameters and over all mean, six genotypes viz., IC-421839, IC-324032, IC-329036, IC-421816, IC-421815 and IC-421834 were stable in performance for dry pod yield hectare^-1 and the genotypes namely IC-421834, IC-421839, IC-421815, IC-324032 and IC-421798 were stable in performance for seed yield plot^-1 (20 plants).
