Variability Studies in Palayankodan Ecotypes (AAB Genomic Group) of Banana (Musa Spp.)

Six Palayankodan ecotypes of banana belonging to AAB genomic group were evaluated for genetic variability among quantitative traits. Genetic and phenotypic coefficient of variation, heritability and genetic advance were estimated for eighteen traits that included plant height, pseudostem girth, numb...

Genetic and phenotypic coefficient of variation, heritability and genetic advance were estimated for eighteen traits that included plant height, pseudostem girth, number of leaves per plant, leaf width, number of suckers per plant, days taken from planting to shooting, total crop duration; length, girth, weight and volume of finger; hand weight, bunch weight, number of fingers per bunch, number of fingers per hand, ripe-fruit weight, sugar/acid ratio and pulp weight.

The volume of finger with low values for GCV, PCV, heritability and genetic advance as per cent of mean implies that it is highly influenced by environment and should not be taken as a criterion for selection.
