Abstract:

Sixty candidate plus trees (CPTs) of Acacia nilotica were selected through intensive survey among six different provenances/ geographical area. Selection was based on the characters of economic interest viz. Straightness, self-pruning ability, clear bole height, low branching habit, disease resistance. Various pod and seed parameters were collected to estimate diversity among different CPTs from various provenances. It was observed that the CPTs were distributed among seven different clusters representing diversity among each other. It was observed that Cluster I was the largest having fourteen CPTs followed by cluster V. Average intra-cluster distance was found maximum in cluster I followed by cluster IV and cluster II while, the inter cluster varied from 2.681 to 5.734, the maximum being between cluster I and VII. The present study revealed that the hybridization between the more divergence genotypes of A. nilotica can produce genotypes with high hetrotic vigour.


Keywords: Acacia nilotica, Candidate Plus tree, Genetic Diversity and Mahalanobis D2 statistic.
