Selection of the parental combinations through multivariate analysis in dessert banana genotypes for hybridization programme
Abstract:
In the present investigation 22 dessert banana genotypes were evaluated under coastal plain zone of Odisha during the year 2013-14 and 2104-15 in a randomized block design with three replications. Observations were recorded on growth parameters and yield attributing traits. Analysis of variance indicated significant differences among the genotypes in respect of all the growth parameters and yield attributing traits. The PCV and GCV (phenotypic and genotypic coefficient variation) were higher for finger weight, bunch weight and number of fingers. Bunch girth and finger weight had very high broad sense heritability (h2). Finger weight recorded the highest genetic advance followed by bunch weight. All the genotypes, on the basis of total variability were grouped into twelve distinct clusters. Maximum number of cultivars was accommodated in Cluster 1 followed by Cluster 7. Inter cluster distance was the highest between cluster 12 and cluster 7. Bunch girth made the maximum contribution to divergence (45.02 %) followed by finger weight (39.83 %).
