Character Association Study on Fruit Yield of Tomato (Solanum lycopersicum L.)

Fruit yield is a quantitative character, which is influenced by a number of yield contributing characters in tomato. To increase the genetic yield potential, maximum utilization of the desirable characters for synthesizing of any ideal genotypes is essential. The present investigation was carried out to determine simple correlation of fruit yield and 29 yield contributing and quality characters. The experiment was conducted at the experimental farm of the department of Vegetable science of VCSG Uttarakhand University of Horticulture and Forestry with 22 different tomato (Lycopersicon esculentum L. ) genotypes. Two yield parameters fruit yield per plant and fruit yield per ha. (0.745) are positive and significantly correlated. Fruit yield per plant is also positive significantly correlated with days to fifty per cent flowering (0.475), fruit density (0.427), tritratable acidity (0.522), fruit infected with insect (0.956) whereas, it is negative and significantly correlated with acidic acid (-0.450), fruit damage with insect (-0.466) and plant infected with disease (-0.945). However, fruit yield per ha is also positive and significantly correlated with number of node first flower (0.495). Therefore these characters can be explore directly to enhance fruit yield in tomato.
