PHENOTYPIC STABILITY FOR SEED YIELD IN GREEN GRAM (Vigna radiata) IN SODIC SOIL

Abstract

A set of five improved advanced, genotypes of green gram were evaluated in summer '92, rabi '92 and Summer '93 seasons in saline/sodic soil conditions (soil pH 8.6, 8.7 and 8.5). Pooled analysis of variances indicated significant differences among the genotypes and the environments. Moreover, the genotype environment interaction was highly significant indicating .differential performance of the genotype under varied environmental conditions. The genotype SSRC 9 showed higher yield and stability of yield performance. The genotype SSRC 7 and CO.5 had high yield stability, better adapted to rich environments, SSRC 6 showed average yield, high stability and better adapted to poor environments.

Keywords: Stability, GXE interaction, Linear Component, Green Gram
