摘要

Pterocarpus angolensis is one of the most valuable timber trees in Tanzania currently extensively exploited. This study was conducted to obtain baseline information on its genetic diversity and population structure in order to formulate effective conservation plans. Random amplified polymorphic DNA (RAPD) markers were used to assess the genetic diversity in Pterocarpus angolensis DC. collected from six natural populations in eastern part of Tanzania. A total of 42 individual plants were analysed using 11 most informative RAPD primers which amplified 73 scored DNA bands showing 75.3% polymorphism. Cluster analysis is used unweighted pair group method with arithmetic average (UPGMA) formed three major clusters which illustrated that most individuals from a given population tended to cluster together and were therefore more genetically similar than individuals from different populations. Most of the genetic variations were found to be high within population 77.13% and low among populations 22.86%. The genetic diversity information of P. angolensis populations reported in this study is very important component for efficient conservation and effective management of its genetic resources.
