STABILITY ANALYSIS IN MUNG BEAN [VIGNA RADIATA (L) WILCZEK] FOR NUTRITIONAL QUALITY AND SEED YIELD

Pooled analysis of variance indicated highly significant differences for genotypes (G), environment (E) and G × E interaction. The partitioning of G x E interaction into linear and non-linear components indicated that both predictable and unpredictable components shared the interaction. Three stability parameters (Mean, b and S2di) were computed to judge the suitable and superior genotype. The deviation from regression for majority of the genotypes was highly significant revealing the unpredictable response of these genotypes and better suitability for sites with better environments. On the basis of these parameters, three genotypes MH 565, SML 668 and ML 776 with higher performance for seed yield, protein, iron and zinc content and highly significant deviation from linearity may be recommended for better environment.
