dc.description.abstractThe present investigation entitled “Stability Analysis of Chickpea (Cicer arietinum L.) Genotypes Under Different Environments” was undertaken with view to estimate stability parameters for seed yield and its important components and to identify most stable genotype under different environments. Twenty genotypes were sown on four different sowing dates in a Randomized Block Design with two replications for measuring stability of genotypes for different characters. The data was subjected to statistical analysis as per Eberhart and Russell (1966) model. In general, genotypic differences were found significant for all character indicating the presence of genetic variability in the material. G x E interaction was found to be significant for the characters viz., days to first flower, days to 50% flowering, number of days to first pod initiation, primary branches per plant (No.), seeds per pod, seed yield (g/plant) and harvest index. Linear component of G X E interaction was found significant for the characters viz., days to first flower, days to 50% flowering, days to first pod initiation, Plant height (cm), primary branches per plant, days to maturity, seeds per pod and harvest index. The genotype JG-14 recorded average stability for days to first flower initiation. The genotype VIJAY recorded average stability for days to 50% flowering. The genotypes RVG-203 and PDKV-KANCHAN exhibited average stability for days to first pod initiation. The genotypes SAKI-9516, DIGVIJAY, PHULE G -0819-43, AKG-70, JG-14 and PKV HARITA recorded average stability for primary branches per plant. The genotype JAKI-9218, PDKV-KANCHAN, PHULE G-0819-43, BDNG-804, PHULE G-13107 and JG-14 recorded average stability for seeds per pod. The genotypes JAKI-9218, PDKV-KANCHAN, PHULE G-13107, PHULE G -0819-43, BDNG-804, JG-14 and PKV HARITA showed average stability for seed yield per plant (g). The genotypes PHULE G-13107, BDNG-804 and JG-14 showed average stability for harvest index. Under late sown irrigated condition, the genotypes JAKI-9218, PDKV-KANCHAN, PHULE G-13107, PHULE G-081943, BDNG-804, JG-14 and PKV HARITA recorded average stability for seed yield (g/plant) hence adaptable to all four types of environments. The genotypes AKG-70 showed above average stability for seed yield (g/plant). None of the genotype was found stable for all the characters under study.en_US
