The Oil Palm Research Institute of Ghana collected 79 dura oil palms from natural groves in seven Ghanaian regions in 2003 with the intention of infusing superior accessions into its breeding stock and retaining those with interesting agronomic traits for posterity, and eighteen (18) agro-morphological traits were studied. To measure the variability within the accessions, the data was subjected to estimates of coefficient of variation. Using R Statistical tools, Principal Component and Cluster Analyses were used to establish the relationship between accessions. Bunch number (28.3), average bunch weight (20.46), fresh fruit bunch (28.43), and single fruit weight (22.37) all had modest coefficients of variance, suggesting that those traits could be enhanced by selection. Five principal components with Eigen values greater than one were found, accounting for 74.82 percent of the total variance. The PC 1 had tributaries in the vegetative, yield, and yield part traits. Eleven accessions had phenotypically diverse phenotypes, and a crossing chart could be started among them to take advantage of their heterosis potential. Cluster analysis revealed two major groups, each of which was further divided into sub-groups, with dissimilarity indexes of 58 percent and 60 percent, respectively. The first cluster contained 49 accessions, while the second contained 30. Six pairs of accessions were found to have similar phenotypes, which may contribute to the formation of dura core collections. Seven high-performing accessions were chosen for their possible infusion into current breeding stocks for five traits of interest in the oil palm industry.
