Abstract:

The specific combining ability variances was much greater than those of general combining ability variances for all the characters except pod yield per plant, which indicated the preponderance of non additive gene action. Among the lines, Prasuna had shown significant positive gca effect for kernel yield per plant. Narayani was found to be good combiner for pod yield per plant as it showed significant and positive gca effect. Among the testers, ICGV-91114 was found to be superior as it showed significant and positive gca effect for number of mature pods per plant, shelling per cent, kernel yield per plant and pod yield per plant. These parents could be used in breeding programme for yield improvement through pedigree breeding. The best specific cross Greeshma×Dharani was found to be desirable for kernel yield per plant. The cross Narayani×Dharani had showed significant sca effect for pod yield per plant. These crosses would be used for further selection to obtain high yielding seggregants.
