Abstract

Studies were undertaken to asses the magnitude of genetic divergence among the progenies of 58 plus trees from the whole distributional range of chir pine in Himachal Pradesh (India) at the age of 5 years to identify the promising selections to be used in future improvement programme. Five growth characters, viz., plant height, collar diameter current year growth, intermodal length and spur dry weight were used to identify the cluster pattern on the basis of Mahalanobis D2 statistics. Based on D2 values, 58 sources were grouped into 11 clusters. The study revealed lack of parallelism between genetic divergence and eco-geographical distribution of the plus trees.
