Abstract

Analysis of variance for Brassica rapa genotypes evaluated using Eberhart and Russell (1966) revealed that all genotypes possess significant difference for yield related traits. Estimation of genetic parameters over locations revealed that the environments were significant. Mean squares due to G × E interaction were significant for all the traits. The component analysis of environment (G × 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 E + (G × E) for all the traits arose due to environments (Linear) and linear response of the regression of the cultivars to environment. Stability performance of all the traits showed significant mean squares for pooled deviation which means prediction of stability could be precise and reliable. The good performance of different traits and their stability across the environment indicated that the genotype KBS-49 and KBS-33 were stable for almost all traits.
