Abstract
Thirty-five genotypes and 3 varieties of chickpea were undertaken to determine the variability, interrelationship among yield and its components and their primary and secondary impact on seed quantity. The research work performed at FoA, Wadura Sopore, SKUAST-Kashmir in the rabi 2017-18. The treatment differences were statistically highly significant for all the traits along with higher magnitude of genotypic and phenotypic coefficient of variation indicating presence of good amount of variability. The character, plant height showed maximum difference preceding by pod number plant-1, days taken to maturity, 50% flowering, seed yield plant-1, 100 seed weight, number of secondary and primary branches plant-1 and seeds pod-1. Genotypic and phenotypic coefficient of variation have been seen maximum in case of seed yield plant-1 preceding by plant height, pod number plant-1, secondary branch number, seeds pod-1 and 100-seed weight. Pod number plant-1, plant height, days to maturity (99%) exhibited maximum heritability (b.s.) then secondary branches plant-1, days to 50% flowering (98%), 100-seed weight, seed yield plant-1 (96%). Seed yield plant-1 showed maximum genetic advance as mean% (54.17) then plant height (50.93) and pods per plant-1 (50.02). The seed yield plant-1 exhibited significant and positive correlation with pods plant-1, secondary branches plant-1, seeds pod-1 and 100-seed weight. By comprehending path coefficient maximum primary effect shown by pods plant-1 on seed yield plant-1 then seeds pod-1, 100-seed weight, primary branches plant-1.
Keywords: Chickpea, genetic variability, correlation, path analysis, pods plant-1, seed yield plant-1.
