Abstract:

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. Among the lines and tester evaluated DMT-3 and PRDS were identified has best general combiners respectively indicating additivity for the parameters. Yield per plant has recorded significant high sca effect in DMT-4 x PRDS which is also found significant for fruits per plant and average fruit weight. Overall significant sca effect was recorded in L-27 x Arka Saurabh for maximum parameters. Fifty crosses evolved by parental combination of resistant x resistant and resistant x susceptible for bacterial wilt showed high resistant to the disease indicating the dominant gene governing the resistance.
