Genetic analysis for yield components in tomato land races

Abstract

The PCV and GCV were high for fruit weight, number of fruits per plant, fruit yield per plant, number of fruits per cluster and number of seeds per fruits. High estimates of heritability along with genetic advance as percentage of mean for fruit weight followed by number of fruits per plan: fruit yield per plant, number of fruits per cluster and seeds per fruits indicated that the role of additive gene action for these traits. Correlation studies revealed significant positive correlations between fruit yield and fruit weight and that of fruit weight with fruit diameter and length at phenotypic level indicting mutual association of these traits. The genotypic evocation coefficients for all the combinations of the traits were higher or quite close to respective phenotypic values, this indicated strong inherent potential as well, therefore, selection on the basis of phenotypic could be quite effective for getting tile desired combination of traits.
