Determination of Correlation and Path Coefficients Analysis for Tomato (Solanum lycopersicum L.) for Yield and Quality Attributes

A study was conducted on 14 genotypes (10 Lines and 3 Testers and a check-‘Pant T1’) of tomato (Solanum lycopersicum L.) at the Vegetable Research Farm of the Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi-221005, during the Rabi season of 2019-20, 2020-21 and 2021-22. The research focused on examining correlations and path coefficients among 15 yield-contributing traits. The experimental design employed was a Randomized Block Design with three replications. The yield per ha was significantly positively correlated with fruit yield per plant (0.943 and 0.876), fruits per plant (0.705 and 710), fruit width (0.266 and 0.296), number of primary branches (0.264 and 0.280), average fruit weight (0.246 and 0.246), pericarp thickness (0.245 and 0.283) and TSS (0.204 and 0.210) at phenotypic and genotypic respectively. Whereas the number of fruits per plant (0.710) showed a significantly positive indirect effect with fruit yield (q/ha) and other traits as average fruit yield per plant (0.876), fruit width (0.296), pericarp thickness (0.283), primary branches per plant (0.280), average fruit weight (0.248), TSS (0.210) and plant height (0.188) are also showed positive indirect impact on fruit yield (q/ha) at genotypic level which specified that yield can be improved by enhancing these attributes.
