Abstract

SummaryBanana with different genomic groups has a greater varietal diversity. New varieties are also developed which have unique tastes, and tolerance to biotic or abiotic stresses. Eleven varieties belonging to different genomic groups are evaluated for their nutrients, secondary metabolites, techno‐functional characteristics, antioxidant activities, glycemic indices, and shelf life. Bioactive profiling was also carried out using Gas Chromatography–Mass Spectroscopy (GCMS). Results revealed that plantain and cooking bananas recorded higher fruit weight than dessert bananas. Pulp to peel ratio was higher in the dessert variety Ney Poovan and dual‐purpose variety Popoulu compared to cooking varieties indicating the presence of a thicker skin. Higher resistant starch (39% dry weight) and lower glycemic index (45%–50%) were observed in Kaveri Saba and Monthan. Total phenolics in ripe bananas were significantly higher than in unripe stages. GCMS results showed the predominance of esters and hydrocarbons among banana varieties and the presence of unique volatiles like linoelaidic acid, 9,12‐octadecadienoic acid in Kaveri Sugantham. PCA and cluster analysis indicated that the biochemical parameters also varied with the genomic groups. The study creates new business opportunities for varieties beyond cv. Grand Naine both in the domestic and export markets.
