ABSTRACT |
The genetic parameters were studied to elucidate the genetic variability, heritability
and genetic advance in tomato (Solanum lycopersicum L.). Evaluation of nineteen
genotypes of tomato was done in augmented block design due to limited
germplasm. The genotypes exhibited a wide range of variability for all the
characters studied. Phenotypic coefficient of variation (PCV) was higher than
genotypic coefficient of variation (GCV) for all the characters studied. High
heritability combined with high genetic advance was observed for the characters plant height, number of clusters per plant, number of flowers per cluster, number of fruits per cluster, number of fruits per plant, fruit length, fruit weight, fruit yield per plant, ascorbic acid, acidity, shelf life and TSS. High heritability combined with
high genetic advance indicates that additive gene action plays a major role in
governing these traits and these traits can be improved by simple selection. |
