Abstract:

Genetic diversity was studied in 58 genotypes of oil palm germplasm in Andhra Pradesh and Telangana locations of India. Morphological traits were recorded and subjected to Mahalanobis D2 cluster analysis and principal component analysis (PCA). These 58 genotypes were grouped into eight clusters which show greater genetic diversity in the genotypes. Cluster 7 is the largest one that has 12 genotypes. Intra and Inter cluster distance of clusters was analyzed by D2 and principal component analysis (PCA). According to D2 analysis maximum intra cluster distance was observed in Cluster 5 and minimum in Cluster 4. Maximum D2 inter cluster distance was observed between Cluster 1 and Cluster 6. Similarly in PCA analysis maximum inter cluster distance was observed between Cluster 2 and Cluster 6. These clusters are having greater genetic distance and hybridization of these genotypes with desired traits can develop superior hybrids.


Keywords: Genetic diversity, Clusters, D2 analysis, PCA, Oil palm genotypes.
