Genetic analysis of yield and yield attributing traits of Cape gooseberry genotypes

Abstract

The present investigation was conducted aiming to assess the genetic analysis and observed that the two genotypes, namely NCOH CAP S-9 & NCOH CAP S-13 produced maximum fruit yield per plant (0.51 kg) due to heaviest average fruit weight and number of fruit per plant. Number of branches per plant and fruit weight showed moderate GCV while, number of fruits per plant and yield per plant exhibited high value of GCV i.e. 40.11 and 48.75 have better scope of improvement. Low heritability (0.92 %) accompanied with high genetic advance (29.05) revealed that the trait, number of fruits per plant is governed by additive gene effects and therefore selection based on phenotypic performance may prove useful. The estimates of broad sense heritability values ranging from 0.34 % to 0.97 % indicated more contribution of dominance and epistatic variances for all the traits under study. Estimates of genotypic, phenotypic and environmental correlation coefficients among the eight characters of local populations under study showed significant positive relation with fruits per plant and fruit weight. Plant height was significantly associated with the branches per plant, fruit length, fruit diameter and total soluble solids. Fruit length was significantly associa ted with the fruit diameter.
