Diversity in morpho-pomological attributes and biochemical profiling of bael (Aegle marmelos (L.) Correa) genotypes of North-Western India

Bael is a medicinal cum fruit tree with multipurpose utility and propagated mostly through seeds. The present study aimed to assess and analyse the morpho-pomological and biochemical traits of eighty seedlings grown bael genotypes comparison with two commercial cultivars (NB-5 and NB9) of bael. The significant differences were detected among the genotypes based on the measured morpho-pomological and biochemical traits. The morpho-pomological and biochemical traits of bael exhibited variation ranging from 6.17% to 133.65%. Trunk girth ranged from 29.50 to 63.40 cm and tree spread (N-S) varied 1.00-6.30 m. Fruit length ranged from 4.60 to 12.05 cm and fruit width ranged from 4.64 to 11.72 cm. Moreover, fruit weight ranged from 56.33 to 917.65 g and pulp percentage varied from 58.64 to 81.38%. Soluble Solid Content ranged from 25.90 to 36.77 0brix and ascorbic acid varied from 14.38 to 25.45 mg/100 g. Fruit length was positively correlated with fruit width, fruit weight, pulp percentage, seed length, seed diameter and number of seeds per fruit, while it was negatively correlated with fruit surface and total number of fruit per plant. Principal component analysis showed that 76.66% of the variability observed was explained by the 13 components. Ward cluster analysis using Euclidean distance classified the genotypes into two main clusters. These findings contribute to a better understanding of the diversity and relationships among the studied genotypes, aiding future breeding and selection programs for improved bael cultivation.
