The experiment was conducted in Department of Horticulture, Agriculture College, Dharwad during the year 2017-18. Fifty crosses were evolved by crossing 10 females (lines) with five males (Testers) in line x tester fashion and were evaluated along with the parents and commercial check in randomized block design. Data was been subjected to line x tester analysis. Analyses of variance were found significant for crosses with respect to yield and quality parameters studied. All the parameters under investigation have recorded significant gca and sca effects in both direction indicating presence of both additive and non-additive components. | Combining ability studies on yield and quality related traits and reaction to bacterial wilt resistance in tomato
