Genetic variability studies in banana I Mysore subgroup (AAB).

Abstract

Eleven accessions Mysore subgroup (AAB) of Musa, representing variability of different banana growing regions of the country were used in the present study, conducted at the National Research Centre on Banana (NRCB), Trichy, Tamil Nadu. This study revealed highly significant differences for most of the characters studied. Moderate GCV values were obtained for bunch weight, no. of leaves at harvest, total no. of fingers, no. of hands and no. of leaves at shooting. The characters bunch weight, breadth of leaf, no. of leaves at shooting, no. of leaves at harvest, no. of hands and total no. of fingers, showed high to moderate heritability and moderate GA. Among these traits, bunch weight should be emphasized during selection owing to its high genotypic coefficient of variability (GCV) values, heritability and genetic advance (GA).
