Summary
Selection of stable and high yielding genotypes is important not only for increasing the agricultural production but also for use in regular breeding programmes. Twenty seven French bean genotypes were evaluated in three different agroecological zones of Himachal Pradesh comprising four environments to study their stability inperformance by following the model of Eberhart and Russell (1966) during summer2008 and 2009. Analysis of variance, means, regression co-efficient (bi) and deviation from regression (s2di) of the individual genotypes were estimated to evaluate the stable performance of the genotypes. The mean squares due to genotypes,environments and genotype-environment interaction were significant for most of the characters studied, which suggests variability among the genotypes for variouscharacters over the environments. Genotype × environment interaction was also foundsignificant for a majority of the traits. The stability analysis showed significance of linear component of variation for important traits including fresh pod and seed yield.On the basis of regression coefficient and mean values, the genotypes ‘Arka Suvidha’,‘DWDFB-1’, ‘DPDFB-1(M)’, ‘DPDFB-2(M)’, ‘IVRFV-1’, ‘IVFB-1’, ‘MFB-2’ and‘MFB-3’ showed stability below average (bi>1) for fresh pod yield, which indicatedtheir specific adoption to favourable environments. Genotypes ‘DWDFB-53’, ‘MFB-4’ and ‘Aparna’ were found to be desirable and stable for high fresh pod yield under unfavourable environments stability above (bi<1) average. Genotype ‘MFB-2’ was observed to be the most stable for seed yield per plant and days to seed maturity over the environments.
