Description Fenugreek is an important Rabi season seed spice crop in India.99 fenugreek germplasm with five checks wereevaluated in Augmented Block Design duringRabi 2019-20 at NRCSS, Ajmer experimental research farm. The-1 -1characters studied were plant height (cm), number of primary branches plant , number of secondary branches plant ,-1 -1number of pods plant , test weight (g) and seed yield plant (g). Data were analyzed statistically for genetic variability,correlation and path analysis for selection of superior genotypes from fenugreek germplasm.The analysis of varianceshowed significant variability for almost all the morphological characters in germplasm lines examined, except-1secondary branches plant . Thephenotypic coefficient of variance (PCV) expressed in terms of percentage werecomparatively high for all the characters than genotypic coefficient of variance (GCV). This study revealed that PCVand GCVwere comparatively high for seed yield plant , number of pods plant , number of primary branches plant andnumber of secondary branches plant . Heritability estimates were found high for seed yield plant , number of podsplant , test weight and number of primary branches plant . High estimates of heritability indicating less influenced byenvironment and direct selection for these yield contributing traits would be effective for future improvement in yield.Estimates of genotypic correlation coefficient is higher than their corresponding phenotypic correlation coefficient for-1all the characters under this study. Seed yield plant had significant and positive correlation with number of branches-1 -1 -1plant , number of secondary branches plant , number of pods plant and test weight at both genotypic and phenotypiclevel. The result of the present investigation on path coefficient analysis also revealed that number of pods plant-1(0.6211) had highest direct effect on seed yield followed by test weight (0.2132), number of primary branches plant(0.0685), plant height (0.0469) and number of secondary branches plant (0.0364). Therefor in order to increase seedyield, more emphasis should be given on positive and direct effect, selection of these characteristics would be morerewarding for fenugreek germplasm.
