Forty five hybrids obtained by crossing fifteen lines with three testers were evaluated to study heterosis and combining ability for grain yield and its component traits. Out of 45 crosses, 42 crosses over better parent and 28 crosses over standard check (DHM 117) significantly out yielded for grain yield. The crosses BM 5050 × BML 10, BM 3511 × BML 7, BM 1234 × BML 10, BM 1234 × BML 13 and BM 5050 × BML 7 had high mean performance and standard heterosis over check DHM 117 for grain yield per plant & other yield contributing characters. Combining ability analysis reveals predominance of non-additive gene action was recorded for all the characters. Among the female lines, BM 5050, BM 1234, BM 3511 and BM 3521 and in testers viz., BML 10 & BML 7 were found to be good general combiners for grain yield and yield component traits. The most promising specific combiners for grain yield and other traits were BM 5050×BML 10, BM 3511×BML 7, BM 1234×BML 10, BM 1234×BML 13 and BM 5050×BML 7. These hybrids can be further tested over locations before releasing as commercial hybrids.
