Abstract:
Pinus wallichiana A.B. (Blue Pine) is one of the India's five native species of Pinus, grows in a variety of climatic, topographical and edaphic conditions in the Western Himalaya. To understand the extent and variation pattern, P. wallichiana populations are evaluated for cone, seed and seedling characters. The results showed that the significant variation in different parameters. The study revealed that all studied traits were inherited additively, except for scale/cone and seed moisture percentage. Additionally, the significant correlation observed between germination traits of seedlings with the altitude, highlights the profound influence of provenance. Therefore, the research findings contribute to designing plantation, improvement and conservation strategies for a species, it signifies a crucial step toward sustainable management practices.
