Estimate of genotypic and phenotypic correlation and path coefficients in tomato (Solanum lycopersicum L.)

The current study was conducted on the tomato crop (Solanum lycopersicum L.) during the autumn and winter of 2024-2025, with the aims of estimate correlation coefficient among quantitative traits and to work out the path coefficient analysis for different traits. The experimental material for the study consisted of 25 genotypes including one check (Kashi Aman), laid in Randomized Complete Block Design with three replications. Observations were recorded on twelve quantitative characters. The most important trait, total fruit yield per plant had exhibited highly significant and positive phenotypic correlation with average fruit weight (0.832), number of fruits per plant (0.753), equatorial diameter (0.655), number of fruits per cluster (0.618) and polar diameter of fruit (0.354).Path coefficient analysis revealed that higher magnitude of positive direct effect on total fruit yield was exerted by average fruit weight (0.656), number of fruits per plant (0.538) and number of fruits per cluster (0.486). While, negative direct effect on total fruit yield per plant was exerted by days to 50 percent flowering (-0.053) and locules per fruit (-0.023).Therefore, based on the information above, it can be concluded that choosing for these features will improve the crop for higher yields and contributing traits.
