Forty-five single cross hybrids of high oil maize were derived using ten parents and evaluated in a randomized block design replicated thrice at Agricultural Research Station (Maize), Amberpet, Hyderabad, during Kharif 2001. Combining ability analysis was carried out to determine their SCA effects for different agronomic, yield and quality parameters namely, days to 50 per cent tasselling, days to 50 per cent silking, days to 50 per cent maturity, plant height (cm), ear height (cm), 100- seed weight (g), grain yield per plot (kg), oil content (%) and protein content (%). The results revealed the predominant role of additive gene action for the traits viz., plant height, oil content and protein content and non-additive gene action for rest of the characters including grain yield. Among the hybrids, four crosses viz., QPM-36 x HOL-65, AML-18 x HOL-65, AML-18 x QPM-48 and QPM-33 x M-210, showed highly significant SCA effects for oil and protein contents along with grain yield and also found promising on basis of per se performance. Hence, these hybrids were recommended for their future multi location evaluation to confirm their consistency before commercial utilization.
