Cooking bananas belong to ABB genome of 45 genotypes were evaluated at Coimbatore for yield and yield attributing characters. Diversity analysis, variability and correlation studies were made. The results evinced that the highest mean bunch weight was recorded in Bagner (17.90 kg) followed by Nalla bontha (17.07 kg), Bargner (17.06 kg), and Pacha monthan (16.91 kg). The finger weight ranged from 231.701g in Pacha Bontha batheesa to as low as 70.41g in Nattu Peyan. Number of fingers were the highest in Octaman (113.89) followed by Chakkiya (109.11). Diversity analysis indicated the functional dissimilarities among genotypes and temporal evolution of genotypes from the wild to the higher hierarchies. Monthan and Buthibale are having genetic similarities. Bagner and Barsain are highly diversed from other entries. Correlation and regression analysis indicated that finger girth is the highly contributing character for bunch weight. The information on yield, phylogenetic relationship, correlation and regression studies on economic traits with yield, help in selection of better and diverse genotypes to utilize in breeding programme. These selected genotypes can be used in breeding programme after assessing male and female breeding potential.
