Abstract: The present investigation was undertaken to study the interrelationship and path coefficient analysis for grain yield and its components in niger germplasm lines. The current experiment was carried out using 54 niger germplasm lines along with three standard checks at University of Agricultural Sciences, Bengaluru, GKVK, during Kharif 2017, material was sown by using augmented design with nine blocks. The character association analysis in niger germplasm lines revealed that plant height, number of primary and secondary branches, Days to 50 % flowering,number of capsule per plant, number of seeds per capsule, capsule diameter and test weight had significant and positive correlations with seed yield per plant. Path coefficient analysis revealed that plant height, number of secondary branches, number of capsule per plant, capsule diameter and test weight had a high positive direct effect on seed yield.
