Abstract

Tomato (Solanum lycopersicum L.) is high value crop, also called as protective food due to its high nutritional and biochemical compounds. Correlation and path analysis was carried out for 147 tomato recombinant inbred line population. Correlation studies suggested that the association of fruit yield per plant was positive and significant with plant height (0.595), branches per plant (0.657), fruits per cluster (0.500), clusters per plant (0.717), average fruit weight (0.244) and fruits per plant (0.891). Path analysis revealed that among eleven characters studied only two characters viz., average fruit weight (0.415) and fruits per plant (0.817) showed very high positive and direct effect on yield per plant. This study helps to understand the mutual relationship among various traits thereby assist in selecting the character contributing to the yield.
