Genetic divergence in Acacia catechu Willd.

Published on

Nine tree attributes were used to evaluate the performance
of forty seed sources of Acacia catechu in a selection
trial. On the basis of 02 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 variabilit~ and/or to get
heterosis in the following generation. 0 analysis served
as a useful tool to understand the nature of genetic
distribution of population within the species.

Keywords: Acacia catechu, seed source, genetic divergenc, 02 statistic.
