Abstract: An experiment was conducted at Research Farm, RVSKVV, College of Agriculture, Gwalior (M. P.). In kharif season 2014 eight parents were grown (received from College of Agriculture, Tikamgarh JNKVV Jabalpur, Madhya Pradesh) for making half diallel crosses [n (n-1)/2] among them and then next year in kharif season 2015 eight parents and 28 F₁ hybrids were grown in RBD with 3 replications for evaluation of yield and yield attributing traits. Five plants from each parent and hybrid were selected randomly for collection of data of different yield contributing characters such as days to peak flowering, days to maturity, plant height, number of primary branches per plant, number of capsules on main axis, total number of capsules per plant, number of seeds per capsule, capsule length, 1000 seed weight and seed yield per plant. Analysis of variance for combining ability revealed that the mean sum of squares associated with GCA and SCA were highly significant for all the characters, and it is noticed that additive as well as non-additive genes were operating in the expression of these traits. Parent RT – 367 was the best general combiner for high yield and early maturity along with most of the yield contributing characters. Parent RT – 368 was also identified as good general combiner for seed yield per plant. Three cross combinations RT -367 X RT -368, LT-210 X RT -367 and JLS-302-11 X AT -249 identified as good specific combiner for seed yield and its contributing characters. Cross LT-210 X RT -367 showed highly significant negative SCA effects in desirable direction for early flowering and early maturity traits.
