Ten restorer lines were crossed in diallel fashion excluding reciprocals to obtain 45 crosses to elucidate the information on the combining ability posses by them for seed yield, yield components and oil content. 45 crosses were evaluated on 11 different quantitative characters. Among 10 restore lines ID-3/147 R was found best general combiner for seed yield per plant and oil content, while cross 298R x  ID-3/147 R was found best cross combination for seed yield per plant and 274R x BC-3-1R for oil content. The cross combination BC-3-1R x ID-3/147 R found promising seed yield and its contributing characters including oil content. The parental genotype ID-3/147 R found involve in most of promising crosses which revealed its potential to transfer desirable characters in progeny /good combiner.
