Estimation of genetic variability for Kabuli chickpea (Cicer arietinum L.) under timely and late sowing condition

Abstract

Fifty diverse Kabuli chickpea genotypes sown under timely and late sowing conditions (D0 & D1) during rabi season of 2016-17. Analysis of variance revealed that significant differences among the genotypes for all the characters under different sowing condition viz, timely (D0) and late (D1). High PCV and GCV were accounted for the traits number of primary branches per plant, seed yield per plant and 100-seed weight under timely and late sowing condition. The values of phenotypic coefficient of variation in both sowing conditions (D0 & D1) were higher than that of genotypic coefficient of variation for all the traits studied, indicating more influence of environment on the expression of these characters. Number of primary branches per plant, number of secondary branches per plant, plant height, reproductive phase duration, days to 50 per cent flowering, number of pods per plant, seed yield per plant and 100-seed weight noted for high heritability along with high genetic advance as percentage of mean. The high heritability values indicated that heritability may be due to higher contribution of genotypic component in these traits.
