Genetic divergence in Acacia catechu Willd

Nine tree attributes were used to evaluate the performance of forty seed sources of Acacia catechu in a selection trial. On the basis of D² analysis, all the seed sources were grouped into fifteen clusters. The pattern of distribution of seed sources in different clusters indicated that genetic divergence did not agree to the geographical differentiation. Seed source S38 of cluster X recorded higher cluster mean values and therefore was recommended for selection. Seed sources from cluster XIV and XV may be utilized as parents in the hybridization program to release greater variability and/or to get heterosis in the following generation. D² analysis served as a useful tool to understand the nature of genetic distribution of population within the species.
