Abstract

In the present study 17 local genotypes were evaluated in three diverse locations during 2008-09 with observations recorded on maturity, morphological and yield parameters. Analysis of variance revealed that the genotypes exhibited highly significant genetic variability for all the traits viz., day to 50 per cent flowering, days to maturity, number of branches plant-1, number of pods plant-1, pod length, number of seed pod-1, 100-seed weight, seed yield plant-1 and protein content. The mean squares due to environments were also significant for all the traits indicating the environments selected were random and were different in agro-climatic conditions. Interaction of genotypes with the environment (G x E) were observed to be significant for all the traits except number of branches plant-1 and protein content. Based on the stability parameter of Eberhart and Russel model, SAUAR 28 was considered as stable and average responsive to the environments for yield and most of the component traits.
