Genetic variability, correlation and path analysis in fenugreek (Trigonella foenum-graecum L.)

Abstract

Genetic variability, heritability, correlation and path analysis were estimated among 28 fenugreek genotypes for 11 quantitative traits. The highest genotypic and phenotypic coefficients of variation were observed for dry matter content and dry weight at flower initiation. High heritability was observed for dry matter content and plant height. The highest genetic advance as percentage of mean was recorded for dry matter content and dry weight at flower initiation. The biological yield (0.819**), No. of pods per plant (0.715**), plant height (0.415**), dry matter content (0.389**), dry weight at flower initiation (0.376**) and 1000-seed weight (0.297**) exhibited positive and significant correlation with the seed yield per plant. Path coefficient analysis revealed that dry matter content had highest direct effect on seed yield followed by plant height and No. of seeds per pod.
