Abstract

The present study was conducted to identify the nature and magnitude of genetic variability, correlation and path coefficient analysis among forty eight fenugreek genotypes under normal and moisture stress conditions in a randomized block design with three replications. The pooled analysis of variance indicated a significant interaction between genotypes and environments for majority of the traits. The analysis of variance for individual environments indicated the existence of significant variability for all the characters, justifying the selection of genotypes for the study. The values of phenotypic coefficient of variation were higher than the genotypic coefficient of variation indicated effect of environment on expression of all characters. The satisfactory estimates of coefficients of variation were recorded for pods per plant and seed yield per plant. High heritability coupled with high genetic advance as a percentage of mean was observed for pods per plant in both environments. The correlation and path coefficient analysis showed that pods per plant had a positive correlation with a high direct effect on seed yield. The results indicated that selection may be worthwhile for pods per plant due to lesser influence of environment and predominance of additive gene action in the genotypes for increasing seed yield.
