Estimation of genetic variability, correlation and divergence studies on seed yield and its attributing characters in fenugreek (Trigonella foenum-graecum L.)

Ninety nine germplasm of fenugreek (Trigonella foenum-graecum L.) along with five checks were evaluated in augmented block design in five blocks at ICAR-NRCSS, Ajmer (Rajasthan) during 2019-20. Analysis of variance revealed significant variability for most of the traits. High heritability was obtained for plant height (97.02), primary branches/plant (77.94), secondary branches/plant (80.54), number of pods/plant (99.55), number of seed/pod (91.12), test weight (90.55), seed yield (99.98).Number of pods per plant and seed yield had high heritability with high genetic advance. Seed yield showed significant positive association with primary branches per plant, secondary branches per plant, no. of pods/plant, and no. of seed /pod and 1000 seed weight. The genetic diversity among tested genotypes was assessed. The genetic divergence grouped into five clusters. The maximum inter cluster distance was observed between I & V (388.24) followed by cluster III & V (387.11).
