Abstract
Variation in different seed morphological and fatty oil contents were studied among 25 seed sources from Punjab, Himachal Pradesh, Jammu & Kashmir and Uttranchal. Though statistically significant differences were found for fruit diameter, number of seeds in a fruit, seed length, seed width, seed thickness, weight of 100 whole seeds, weight of seed coat of 100 seeds and weight of kernels of 100 seeds among different sources, no seed source was found to be the best for all traits. Seed source S20 (U.P. Dunera, Gurdaspur Forest Division) gave the maximum oil content of 33.10 per cent, which however, was much lower as compared to Chhindwara source of Madhya Pradesh which is reported to yield 39.12 per cent oil (on whole seed basis). The study, therefore, cautions that provenance research should be done before undertaking large scale plantations to avoid any unsavoury situation.
