Abstract:
Forty one genotypes were used to study genetic variability, heritability and genetic advance in tomato (Solanum lycopersicum L.). The analysis of variance revealed highly significant variation among the genotypes for all the characters studied indicating considerable amount of variability among the genotypes. High genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were observed for average fruit weight, fruit volume, number of fruits per plant, number of locules per fruit, yield per plant, yield per plot, yield per hectare, ascorbic acid, pericarp thickness and titratable acidity. This indicates the existence of broad genetic base, which would be amenable for further selection. High heritability coupled with high genetic advance over mean were observed for fruit length, fruit diameter, average fruit weight, fruit volume, number of locules per fruit, number of fruits per cluster, number of fruits per plant, yield per plant, yield per plot, yield per hectare, TSS, ascorbic acid content of fruit, lycopene content, titratable acidity, pericarp thickness and firmness.
