A research work on genetic variability, analysis was estimated in 21genotypes of fenugreek (Trigonella foenum-graecum L.) grown in a Randomized Block Design (RBD) with three replications during Rabi season of 2016-17 at the research farm of ICAR-National Research Centre on Seed Spices, Tabiji, Ajmer (Rajasthan). Analysis of variance were estimated for days to 50% flowering (2.37*), days to maturity(24.45**), plant height (110.82**), number of primary branches per plant (0.56*), number of secondary branches per plant (1.32*), number of pods on main axis (5.20**), number of pods per plant (98.96**), pod length (1.03*), number of seeds per pod (1.74*), test weight (2.06*), seed yield per plant (2.31*) and seed yield per plot (38997.63**). The highest estimates of PCV along with GCV were found for seed yield per plot (21.51), number of pods on main axis (13.39) and number of pods per plant (11.13) while, moderate to high PCV and GCV were found for the characters viz., plant height, number of primary branches per plant, number of secondary branches per plant seed yield per plant and reaming characters viz., test weight, pod length, number of seeds per pod were found low. The estimates of heritability was found very high for seed yield per plot (98.24) and number of pods on main axis (95.27)while, low for days to 50% flowering(46.21). The genetic advance was recorded highest for seed yield per plot (43.92) and number of pods on main axis (26.29) while, low in days to 50% flowering (1.92). Genotypic and phenotypic level revealed that the seed yield was significantly and positively correlated with plant height (0.657*), number of pods on main axis (0.442*), number of pods per plant (0.345*), number of primary branches per plant (0.439*) and days to maturity (0.446*). Path coefficient analysis of different characters contributing towards seed yield per plot showed that seed yield per plot (1.25) had highest positive direct effect followed by test weight (0.668), pod length (0.535) and number of seeds per pod (0.346).
