In the present study, 40 genotypes of neem were collected from different regions of Telangana, Tamil Nādu, Karnataka and Rajasthan to evaluate their genetic variability for seed traits. Significant variation was observed among all the genotypes for all the seed characters. The seed attributes viz., hundred seed weight, seed length and seed width contribute either independently or in conjunction with one another, in promoting high azadirachtin content. Hundred seed weight, germination percentage and azadirachtin percentage recorded higher GCV, PCV and genetic advance as percent of mean, whereas all the seed traits exhibited high heritability, which is indicative that selection based on these seed traits would be effective for the exploitation of genotypes yielding high azadirachtin content.
