Abstract

An investigation consisted of 50 chickpea genotypes including 4 checks viz., JG64, ICC10685, ICC4567 and NBeG47 was conducted during the rabi season of year 2022-23 at Seed Research and Technology centre, Rajendranagar, Telangana. The objective of the study was to estimate magnitude of different parameters of genetic variability for yield and its attributes. The observations were recorded for thirteen different yield and its contributing characters and the results obtained  indicated that in general the phenotypic coefficient of variance was found to be higher as compared to genotypic coefficient of variance for all studied traits. High heritability along with high genetic advance (% mean) was obtained for characters like number of seeds per plant, number of filled pods per plant, seed yield per plant, number of pods per plant, number of primary branches, 100 seed weight, number of secondary branches, and plant height at normal sown conditions, which determines the presence of additive gene action for these characters and in late sown conditions the characters like number of seeds per plant, number of filled pods per plant, seed yield per plant, number of pods per plant, number of primary branches, 100 seed weight, number of secondary branches, and plant height and harvest index had shown high heritability along with high genetic advance. So, it determines the presence of additive gene action for these characters. So, that selection for these characters is beneficial in the breeding programmes.
