Study of character association in the tomato genotypes

Author(s):
Taru Dumi, Vipin Kumar and Archi Gupta
Abstract:
Tomato is a very important vegetable crop grown all over the world. Study was done on 36 genotypes of tomato for correlation and path coefficient for different characters. Study of correlation between different quantitative characters provides a thought of association that would be effectively exploited to formulate selection strategies for improving yield components. Correlation coefficient studies indicated that genotypic correlation coefficient was higher than phenotypic correlation coefficients for most of the characters. Fruit per hectare expressed highly significant and positive correlation with fruit weight, number of fruits per plant and number of primary branches and plant height and days to first fruit set showed positive correlation which implies that these characters were the prime contributing factors to fruit yield. The path coefficient technique helps in estimating direct and indirect contribution of various components in finding out the total correlation towards yield. The highest positive direct effect on weight of fruits per hectare was observed on fruit weight followed by days to first fruit maturity and number of primary branches.
