Variability and correlation analysis in fenugreek (Trigonella foenum-graecum L.)

Abstract

Thirty genotypes of fenugreek (Trigonella foenum-graecum L.) were evaluated for genetic variability, correlation and path coefficient analysis at College of Horticulture, Mandsaur (Madhya Pradesh) during rabi 2012-13. The highest genotypic and phenotypic coefficient of variances were observed for dry weight per plant at flower initiation (g) followed by straw yield per plant. The highest genetic advance was observed for dry matter content per plant (g) followed by number of pods per plant, biological yield per plant (g) and plant height (cm). The highest heritability was observed for protein content (%) followed by number of pods per plant, dry weight per plant at flower initiation (g), and chlorophyll content in leaves. Seed yield per plant showed significant and positive correlation with dry matter content per plant (g), biological yield per plant (g) and 1000 seed weight (g). Path coefficient analysis indicated the highest positive direct effect of biological yield (g) on seed yield per plant (g) followed by dry matter content per plant (g) and number of seeds per pod. It was concluded that improvement of seed yield in fenugreek is possible through selection for dry weight per plant at flower initiation (g), protein content (%), biological yield per plant (g), number of seeds per pod and 1000 seed weight (g).
