Description |
Fifty genotypes of chickpea were evaluated in three different environments for the nature of variability and stability for eleven traits viz., days to 50% flowering, days to maturity, plant height , number of branches per plant, number of pods per plant, number of seeds per pod, biological yield, seed yield per plant, harvest index (%), 100 seed weight and protein content ( %). Analysis of variance revealed significant differences among the genotypes for all the characters studied. The highest GCV and PCV were observed for number of branches per plant followed by 100 seed weight, number of pods per plant, seed yield per plant, biological yield per plant. The highest heritability value was registered for protein content (%), plant height, days to 50% flowering, seed yield per plant, biological yield per plant. Genetic advance as % of mean was highest for 100 seed weight in E1 and E2 followed by seed yield per plant for number of pods per plant in E3 followed by number of branches per plant, harvest index and seed yield per plant. In the present study high heritability estimates accompanied with high genetic advance were observed for 100 seed weight in all the three environments. These genotypes were grouped into eight clusters each in first two environments (E1, E2) and into nine clusters in environment three (E3). On overall basis genotypes HC-3, HK-3, HK06-169, HK06-151, H05-10, H06-07, H06-32 and H07-23 were observed quite divergent in all the environments and could be used in hybridization programme for obtaining superior recombinants. Pooled analysis indicated wide differences between environments and differential behaviour of genotypes in different environments. Stability analysis showed that a major portion of genotype × environment (G × E) interaction was accompanied by linear component for days to 50% flowering, days to maturity, number of branches per plant, number of pods per plant, number of seeds per pod, biological yield, seed yield per plant, 100 seed weight, whereas, non-linear portion predominantly contributed towards plant height, number of branches per plant, harvest index and protein content (%). Environment two (E2) was observed to be best for most of the yield attributing traits. Based on stability parameters genotypes H06-79, H04-31, HK05-151, HK06-162, HK06-170, HK06-171, HK-2, HK-3, H06-32 were found stable in better environmental conditions, genotype HC-3 for poor environment and genotypes H05-10, HK06-152, HK06-155 across the environments. |
