The experiment comprising one hundred twenty four diverse genotypes, grown in augmented block design during Rabi 2016-17. The study revealed that the in general, genotypic correlation coefficients were higher in magnitude and similar in nature than the corresponding phenotypic correlation, suggesting therefore, a strong inherent relationship in different pairs of characters in fenugreek genotypes. Seed yield per plant had exhibited highly significant and positive phenotypic correlation with pods per plant, secondary branches per plant, primary branches per plant, and length of pods. The higher magnitude of positive direct effect on seed yield per plant was exerted by pods per plant followed by secondary branches per plant.While negative direct effect on seed yield per plant by either of the dependent traits was very low.
