Abstract:

Fifty nine genotypes of tomato were used to study the association and path coefficient analysis of fourteen yield related quantitative traits during the year 2014 and 2015 (January to June). Fruit yield was found significantly and positively correlated with number of fruits per plant (0.630, 0.558) followed by average fruit weight (0.291, 0.215) while it was significantly and negatively correlated with days to first fruit ripening (-0.539, -0.382) and days to 50% flowering (-0.399, -0.248) for both the years respectively. Path analysis confirmed that the number of fruits per plant had highest positive direct effect (0.753, 0.855) on fruit yield followed by average fruit weight (0.661, 0.464). The average fruit weight and number of fruits per plant exhibiting significant positive correlation and direct effect on fruit yield, emerged as the important components that contributed to fruit yield. Hence, these characters should be given due weightage during the selection of genotypes as selection primarily based on these traits may result in the development of high yielding varieties.
