Divergence, heritability, jackfruit, variability


The present study was conducted with 24 jackfruit genotypes selected from six different districts of Assam, India to investigate the extent of variability and diversity among the selected genotypes. Wide variability was observed for desirable traits like fruit weight, number and weight of flakes/kg of fruit weight, TSS, ascorbic acid, total carotenoid, total flavonoid content and total antioxidant activity. The heritability for quantitative and qualitative traits ranged from 84.26% to 99.94%. Fruit weight showed significant positive correlation with leaf width, fruit length, fruit diameter and weight of flakes/kg of fruit. The highest contributor to genetic divergence among quantitative characters was fruit weight (52.50%), followed by number of flakes/kg of fruit (17.32%), among qualitative characters, it was reducing sugar (85.27%), followed by TSS (10.84%). Further, these twenty-four genotypes were grouped into three clusters for quantitative characters and five clusters for qualitative characters.
