The present investigation is regarding effect of seed source variation in cone and seedmorphology, germination and early seedling growth of Pinus wallichiana. Cones werecollectedfrom10differentseedsourcesinGarhwalHimalayanregion.
Among the seed sources, highest cone length, cone diameter, cone weight and seed percone were found in Harshil. Highest scale per cone was found in Gangotri and Harshil.Gangotri showed highest seed length without wing, seed width and seed thickness. Seedweight(100 seed), seedmoisture and plumule–radicle ratiowas foundmaximum inAuli.

With respect to variability the cone weight, seeds per cone, seed weight with or withoutwing, germination value, plumule length, radicle length, seedling length and plumule -radicle ratio showed better results as compare to others. Therefore, it is concluded thatGangotri and Harshil showed dominance with respect to different traitsamong all theseedsources.
