The present investigation was carried out under AICRP on Vegetable Crops at Horticultural Research cum Instructional Farm, Department of Vegetable Science, IGKV, Raipur (C.G.) during rabi 2016-17. The 22 tomato (Solanum lycopersicum L.) genotypes were evaluated to estimate the nature and magnitude of associations of different characters with fruit yield (q/ha). The experiment was conducted using Randomized Block Design (RBD) with three replications. An overall observation of correlation coefficient analysis revealed that average fruit wt. (0.792, 0.735), fruit diameter (0.751, 0.705), number of fruits per cluster (0.636, 0.520), number of flowers per cluster (0.620, 0.520), fruit yield per plant (0.584, 0.559), ascorbic acid (0.441, 0.355) and number of fruits per plant (0.415, 0.352), exhibited the significant positive correlation with fruit yield (q/ha). Hence, direct selection for these traits may lead to the development of high yielding genotypes of tomato. In case of path analysis fruit diameter (11.003), fruit yield per plant (5.646), plant height (5.363), days to first fruit harvest (4.913), number of fruits per cluster (3.052), number of branches per plant (1.206) had highest positive direct effect on fruit yield (q/ha) hence, indicating their true positive and significant association with fruit yield (q/ha). This indicated that these traits play important role in yield improvement. This implies that direct selection for these characters might be effective and there is a possibility of improvement in fruit yield.
