Abstract:
In the present investigation eight parents were grown for making half diallel crosses [n (n-1)/2] among them and next year eight parents and 28 f1 hybrids were grown in CRBD with three replications for evaluation of yield and yield attributing traits to assess the combining ability was carried out by using the procedure given by griffing (1956) of method 2 model. Analysis of variance for combining ability revealed that the mean sum of squares associated with gea and sea were highly. Significant for all the characters except for plant height and it is noticed that additive as well as non- additive genes were operating in the expression of these traits, indicating existence of hudge amount of genetic variability in the experimental material. Parent TKG-22 was the best general combiner for high seed yield and early maturing along with most of the yield attributing traits. Parent JLS-120 was also identified as good general combiner for seed yield along with most of the yield contributing traits. Five cross combination Viz JTS-8xTKG-22, JTS-8xJLS-120, PT-2xJLS-120, RT-366xTKG-22 and MT-11-8-2xRT-368 identified as good specific combiner for seed yield and its contributing characters. Cross RT-366xRT-368 showed highly significant negative sea effects in desirable direction for early maturing.
