ASSESSMENT OF GENETIC VARIABILITY, CHARACTER ASSOCIATION AND PATH ANALYSIS IN TOMATO (S. LYCOPERSICUM L.) UNDER TARAI CONDITION OF UTTARAKHAND
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 34
Abstract
The research work was carried out to analyse the variability parameters, correlation and path coefficient for morphological characters and quantitative traits in twenty five tomato genotypes. Analysis of variation revealed significant differences between the genotypes for all the traits. High genotypic and phenotypic coefficient variation were observed for average fruit weight followed by number of fruit/plant and number of fruit cluster/plant and lowest for days taken to first fruit harvest. High genetic advance was obtained for fruit yield/ plant, yield/ hectare and plant height. fruit yield quintal / hectare was positively and significantly correlated with average fruit weight and fruit yield/plant. Maximum positive direct effect on fruit yield / hectare was imposed by number of primary branches / plant followed by days taken to 50% flowering and number of fruit cluster/plant. Whereas, at genotypic level, maximum positive direct effect on fruit yield/hectare was imposed by plant height followed by days to flower initiation and days taken to first fruit set. The genotypes viz., CLN-2123E (364.03 q/ha), EC-519800 (355.15 q/ha) and CLN-2870A (351.74 q/ha) were found better than to check PT-3 and superior for yield quintal / hectare.
