Fifty-two seed sources of Pongamia pinnata were collected from different geographical regions of Haryana, Rajasthan and Uttar Pradesh. Morphological data on pods and seeds were taken to assess the genetic variability. Significant genetic variability between seed traits (length, breadth, thickness, 100-seed weight and oil content) and pod traits (length, breadth, thickness and IOO-pod weight) was recorded. Oil content in the seed ranged from 28.67; in RJ-lI to 47.02; in RJ-2. Higher magnitude of phenotypic coefficients of variation (PCY) than the corresponding genotypic coefficients of variation (GCY) for all the characters indicated the impact of environmental changes on the expression of traits. High heritability coupled with high genetic gain was recorded for IOO-pod weight indicating the importance of additive gene effects.
