Abstract:
The experimental material in the present study consisted of 60 germplasm lines of chickpea and four checks. These lines were evaluated in augmented design for variability, heritability and genetic advance during rabi 2021-22. The analysis of variance unveiled presence of significant variations among the genotypes for all twelve traits. The variability estimates calculated had higher PCV values over GCV. The highest PCV value was recorded for seed yield per plant. High PCV coupled with high GCV along with less difference in between GCV and PCV indicated the presence of wider adaptability for these traits in the genotypes studied and less influence of environment in the expression of traits. All the traits under investigation were found to be highly heritable, as majority of them showed high values of heritability (broad sense) estimates. Highest value of heritability estimate was recorded for seed yield per plant. High heritability coupled with high genetic advance as percent of mean indicated operation of additive gene action and the ample scope for improvement in these traits through simple selection.
