Genetic Association and path coefficient analysis among yield and yield related traits in Tomato (Solanum lycopersicon MILL.)
Abstract
The proposed research study was conducted at the experimental field of Department of Horticultural Research and Development, National Agricultural Research Centre, Islamabad. The aim of this study was ̔ ̔Genetic association and path coefficients analysis among yield and yield related traits in Tomato (Solanumlycopersicon MILL)̕̕.̕Total eight parents and 15 F1s were evaluated in proposed experiment. Correlation analysis showed that plant height, number of branches plant-1, number of clusters plant-1, number of flowers cluster-1, number of fruits cluster-1, single fruit weight and fruits setting percentage cluster-1exhibited significant correlation with yield plant-1 at genotypic level and highly significant at phenotypic level and these traits could be used as selection criteria for improvement of yield plant-1.Path analysis revealed that plant height, number of branches plant-1, number of clusters plant-1, number of flowers cluster-1, single fruit weight and fruits setting percentage cluster-1 were directly contributing to yield improvement.
