【 摘 要 】

Combining ability was studied among 24 crosses involving eight lines and three testers. The general andspecific combining ability variances were highly significant for all the characters studied. The parent VRI Gn 6proved to be a good general combiner for yield and yield components. Three crosses viz., VRI Gn 6 x GAUG10, VRI Gn 6 x VRI 2 and VRI 4 x UG 9 exhibited desirable sca effects and also recorded higher per seperformance. Most of the crosses involved parents with high x low gca effects which showed the involvementof non-additive gene action in controlling these characters.
