Abstract

The current study was designed to assess variances between genotypes and within genotypes, estimate genetic parameters, and identify promising genotypes for future utilization from the pooled population of the cross 16P2 × Kashi Hemanth in tomato (Solanum lycopersicum L.). The evaluation was done in the farmers' field at Kanaykanahalli village, Belurtaluq, Hassan district during 2020-2022. Analysis was done for 29 ABLs along with five checks in RBD design. Traits such as plant height, number of branches, number of fruits per plant, average fruit weight, yield per plant, fruit length, fruit width, number of locules, pericarp thickness, TSS, firmness, and lycopene exhibited high heritability and genetic advance as per cent mean. These findings put forward the contribution of additive gene effects to the heritability of these parameters, suggesting significant potential for improvement through selection.

Conclusion

The ratio between genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) exhibited minimal variations implying that environmental factors had limited influence on the expression of most traits. Traits such as plant height, number of branches, number of fruits per plant, average fruit weight, yield per plant, fruit length, fruit width, number of locules, pericarp thickness, TSS, firmness, and lycopene exhibited high heritability and genetic advance as per cent mean, suggesting significant potential for improvement through selection.
