ABSTRACT
An experiment was conducted during rabi 2016-17 at Agronomy Farm, S.K.N. College of Agriculture, Jobner with 48 genotypes of fenugreek in randomized block design with three replications to estimate the genetic variability, heritability, genetic advance and character association for nine quantitative characters. The analysis of variance showed mean squares due to genotypes were highly significant for all the characters indicated that considerable amount of genetic variability was present in the experimental material. In general, the PCV were higher than the corresponding GCV for all the characters studied, which indicated effect of environments on the character expression. High estimates of GCV and PCV were observed for pods per plant, seed yield per plant and plant height. The estimates of broad sense heritability were high for seeds per pod followed by plant height, pods per plant, pod length, days to maturity and seed yield per plant. Genetic advance as percentage of mean was high for pods per plant and seed yield per plant. High estimates of PCV, GCV, heritability and genetic advance were found for pods per plant and seed yield per plant indicating additive gene action in the inheritance of these characters. The association analysis revealed that seed yield per plant was positively and significantly correlated with plant height, pods per plant and 1000-seed weight. On the basis of the present study, it is suggested that in breeding programmes major emphasis should be given during selection for pods per plant and 1000-seed weight as these had good positive correlation with seed yield per plant.
Key word: Variability, Heritability, Genetic advance, Character association, Fenugreek.
