Abstract
Combining ability for grain yield and its components was studied using four cytoplasmic male sterile (CMS) lines and ten testers at Sorghum research unit, Dr. PDKV, Akola, Maharashtra. Mean sum of squares due to lines, testers and line × tester were highly significant indicating the existence of high variability for most of the characters. The estimates of general combining ability (GCA) and specific combining ability (SCA) variances indicated the presence of higher magnitude nonadditive gene action for most of the characters. The line ICS-516A and testers ICSR-44347, AKR-456 was found to be good general combiners for yield contributing traits. The F1 s ICS-40A x ICSR-44347 (5.990), ICS-516 A x ICSR- 44347 (5.196) and ICS-516A x AKR-456 (5.378) were identified with high significant and positive SCA for grain yield.
