 ABSTRACT

The genetic parameters were studied to elucidate the genetic variability, heritability and genetic advance in cherry tomato (Solanum lycopersicum L. var. ceraciformae). Evaluation of thirty six genotypes of cherry tomato was done in randomised complete block design. 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. In the present study, very high heritability (>90%) coupled with very high genetic advance as per cent over mean (>40%) was recorded for the characters viz., plant height at 30 DAT, pericarp thickness, average fruit weight, number of fruits per plant, number of seeds per fruit, thousand seed weight, lycopene content. High heritability with high genetic advance as per cent mean (GAM) was observed in number of primary branches at 60 and 90 DAT, polar diameter, equatorial diameter. Therefore, additive component is predominant here. Thus, there is ample scope for improving these characters through direct selection.

Key words: Cherry tomato; GCV; PCV; heritability, genetic advance and GAM.
