The present study on genetic variability and correlation studies on Nendran ecotypes of banana (Musa spp.) was carried out at Instructional Farm, College of Agriculture, Vellayani, Thiruvanthapuram, Kerala to study for their genetic variability and correlation among the nendran ecotypes of banana. The genotypic and phenotypic coefficient of variation, heritability, genetic advance and correlation coefficient were estimated for seventeen traits which included plant height, number of suckers per plant, number of leaves per plant, leaf width, days taken from planting to shooting, bunch weight, bunch length, hand weight, number of fingers per bunch, number of fingers per hand, length, girth, weight and volume of finger, ripe fruit weight, sugar:acid ratio and pulp weight. A remarkable variability was observed among the collections for these characters. All the characters showed the highest estimates of broad sense heritability whereas genetic advance as percentage of mean recorded higher in traits such as volume of finger, finger weight, ripe fruit weight, pulp weight and number of fingers per bunch. The value of high PCV, GCV, heritability and genetic advance makes it a prime character for the direct selection. Weight of finger, bunch weight, volume of finger and number of fingers per bunch showed high genetic advance and high heritability are the other important characters which have to be considered for selection of the ecotypes.
