Pomegranate (Punica granatum L.), belonging to the family Lythraceae, is one of the oldest and beloved fruit crops cultivated widely in several tropical and subtropical countries. In the recent past pomegranate cultivation is gaining immense popularity in India owing to its dietary and nutraceutical benefits. The present study was conducted with an objective of determining diversity present in the popular pomegranate genotypes of India for different morphological and biochemical traits and to detect the association between the genotypes using Principal Component Analysis (PCA) and Cluster Analysis (CA). Results suggest presence of considerable phenotypic and genetic diversity in the studied pomegranate genotypes. Fruit and aril traits like fruit weight, dry weight of 100 arils, fruit volume, fruit length, peel weight, aril weight and fruit diameter were found to be the most discriminating traits of the Indian pomegranate germplasm under study.
