Seeds were collected from phenotypically superior trees of Bauhinia variegata at 35 geographical locations from the natural distribution area in Himachal Pradesh during March_April and sown in the nursery in the last week of June. After fifteen month's growth, data were recorded on plant height, collar diameter, internodal length, number of branches, number of leaves, leaf area, fresh and dry shoot weight, fresh and dry root weight. The leaf samples were collected and analyzed for mineral nutrients and proximate principles viz., N, P, K, Ca, Mg, dry matter, crude protein, crude fibre, ether extract, total ash and nitrogen free extract. All the traits showed significant differences in the phenotypic characteristics. Estimates of variability and genetic parameters showed that leaf area and plant height were under additive type of gene action. Significant and positive correlation between different characteristics indicated the possibility of indirect selection in the species.
