Abstract

Jamun, a nutritionally and medicinally valuable underutilized tropical fruit, has received limited genetic characterization, particularly with respect to integrated morphological and biochemical diversity across different agro‐ecological zones. Such underexplored variability hampers systematic breeding and conservation efforts. The present study aimed to address this gap by assessing the genetic diversity and trait associations among 60 Jamun genotypes from the western dry tracts of West Bengal, India. Based on 26 morpho‐biochemical descriptors, sustainable variability was recorded in traits such as fruit weight, pulp content, total soluble solids, anthocyanin content, and antioxidant capacity. Principal component analysis identified key traits contributing to the observed variation, with the first three components explaining over 70% of the cumulative variance. Cluster analysis further grouped the genotypes into five distinct clusters, revealing strong inter‐ and intracluster variability. Significant positive correlations were observed between total soluble solids, anthocyanin content, and antioxidant activity, highlighting their potential for nutraceutical enhancement. These findings provide critical insights into the genetic architecture of Jamun , offering a valuable framework for selecting superior genotypes for targeted breeding, germplasm conservation, and value‐added product development. This study underscores the significance of integrated multivariate analysis in unlocking the hidden potential of underutilized fruit species like Jamun , promoting sustainable horticultural development.
