Abstract
Seeds were collected from 42 seed sources and a part of the seeds were used to study seed length, seed width, 100-seed weight, germination, germination value, and germination energy index under laboratory condition. Seeds were sown in the nursery in randomized block design with four replications during June 1999. After six months of growth in the nursery, data were recorded on 10 randomly selected seedlings per treatment for field germination, seedling height, collar diameter, needle length, dry shoot weight, total carbohydrates, total sugar, starch, reducing sugar, non reducing sugar, phenols and amino acids. The study revealed that all seed traits, laboratory germination traits, morphological traits and all biochemical traits showed significant variation. Highest heritability estimates in conjunction with high genetic gain of field germination are more reliable in predicting the resultant genetic progress through selection.
