ABSTRACT

Thirty tomato genotypes were assessed in a randomized block design with three replications at S.V. Agricultural College, Tirupati, during rabi 2023-24, to assess the character associations between yield, Yield attributing and quality characters. The yield plant-1 recorded positive and significant correlation with days to 50 per cent flowering (0.33* and 0.27*), plant height (0.43** and 0.39**), fruit weight (0.30* and 0.23*), fruit diameter (0.35** and 0.28*), number of locules in fruit (0.26* and 0.22*) and seed test weight (0.60** and 0.37**) at genotypic and phenotypic levels respectively. The path coefficient analysis suggested that the characters like plant height, average fruit weight and seed test weight should be prioritized during selection to enhance the fruit yield plant-1 of tomato. Simultaneous selection for these characters would result in the improvement of yield plant-1.
