Stability Analysis of Elite Chickpea Genotypes Tested under Diverse Environments

Twelve elite chickpea genotypes along with two check varieties were grown at four diverse locations in Punjab province to check their stability. The analysis of variance for seed yield at individual locations showed significant to highly significant differences between genotypes. Pooled analysis of variance over locations displayed highly significant differences between genotypes, locations and genotype x location interaction. Among 14 genotypes, the maximum mean seed yield over the locations was produced by the CC119/00 (1.229 t ha{-1}) and the highest mean seed yield producing location was NIAB (1.412 t ha{-1}). The cluster analysis effectively grouped the locations and genotypes into three clusters each viz. low, medium and high yielding ones. G x E interaction was of crossover in nature. Partitioning of total variance revealed significant differences among environments and genotypes for grain yield demonstrating the presence of considerable variations among genotypes as well as diversity of environments at various locations. The analysis of stability based on mean grain yield, regression coefficient and deviation from regression revealed that the genotypes; CC119/00, CC117/00 (Colchicine mutants), CM256/99, CH38/00 and K-70022 were most stable and adapted to the diverse environmental conditions of Punjab. Previously colchicine was only known to cause chromosome doubling but now it is also known to induce mutations. This is the first report of the systematic work on the mutants induced through colchicine treatments and demonstrated their yield superiority and stability over the locations. These genotypes are recommended for commercial cultivation and can also be effectively utilized in the recombination breeding programs to enhance genetic variability in kabuli chickpea.
