Study on Per Se Performance and Heterosis for Green Cob Yield and Its Attributing Traits in Sweet Corn (Zea Mays L. Saccharata)

Abstract

Heterosis is the potential tool to achieve sustainability in crop production. Identifying appropriate parental combinations is a prerequisite for deriving the highest level of heterosis, which is of immense value for commercializing hybrids. In the present experiment, fifty hybrids were generated by crossing ten lines with five testers using line × tester mating design in sweet corn. Fifty hybrids and their respective parents were evaluated along with the standard check sugar 75. Based on per se values, the lines L 1 , L8, L 7 and L 10 and tester T 1 and T 5 were considered superior for green cob yield, while in the case of hybrids, L
