The goal of this work was to find F1 hybrids that may be used to boost grain production, protein, and oil in maize by utilising heterosis (Zea mays L.). For thirteen critical features in Line x Tester mating design, the amount and nature of heterosis was researched at College of Agricultural Farm; Rajendranagar. Six lines and four testers resulted in twenty-four crossings. It was done in an irrigated environment with three replications using a randomised block design. The findings of this investigation revealed that non additive gene activity occurs for grain yield, oil, and protein. With a value of 31.95 percent, B-QPM-117x B-QPM-128 was the only hybrid with positive and extremely significant standard heterosis for grain yield over DHM-105. As a result, this cross can be a good substitute for the DHM-105 check. Only hybrid B-QPM-114x B-QPM-118 demonstrated the highest positive standard heterosis for oil content with a value of 0.71 percent and grain yield per plot with a value of 20% over the check Mandhuri, however it was not significant. Over this check, however, all other crosses showed negative and significant standard heterosis for oil and protein contents. This hybrid has the potential to increase oil content. Five hybrids showed positive and significant performance for grain yield in heterobeltiosis studies. In addition, three hybrids showed significant and positive heterobeltiosis for protein content.
