Abstract:
In the present study 31 genotypes were evaluated for stability performance across four diverse locations using Eberhert and Russel model. Analysis of variance revealed that all genotypes possessed significant difference for various yield related traits. Estimation of genetic parameters over locations revealed that the environments were significant. Mean squares due to G X E interaction were significant for all the traits. The component analysis of environment (G X E) revealed significant mean squares for all the traits. Mean squares of linear and non-linear components revealed that environments (linear) were significant for all the traits and the significant mean squares for environment + (G x E) for all the traits arose due to environments (Linear) and linear response of the regression of the cultivars to environment. The good performance of different traits and their stability across the environment indicated that the genotype WB-416, WB-195, WB-1139, WB-360, WB-30 and WB-1136 were stable for many traits. These genotypes would be useful for commercial exploitation or can be exploited as elite gene pool for future breeding programmes.
