Six medium-season commercial maize (Zea mays L.) hybrids were evaluated in RCBD with three replications, as sole crop as well as all possible half diallel mixture combinations by mixing equal quantity of seed, during kharif, 2015 at college farm, College of Agriculture, Rajendranagar. The hybrids comprises of both public as well as private sector. Data were recorded for grain yield and its components. Among 15 combinations, two hybrid mixtures viz., DHM-117 + NMH-1247 and DHM-121 + NMH-1247 recorded high per se of 8-20 % and significant competitive ability over the sole high yielding genotype. The hybrids that yielded highest in pure stands contributed more to a mixture than would be expected based on their pure stand yield and the lower yielding hybrids contributed less than expected. Cross-pollination boost to seed yield is greater from two hybrids that have different parentage or sources.
