Six popcorn varieties were crossed in a diallel mating scheme to obtain 15 F1 hybrids, with the purpose of analyzing the estimates of heterotic parametrization for agronomically important traits.
The genitors and hybrids were evaluated in randomized block design with three replications in Viçosa and Visconde do Rio Branco, in Minas Gerais State, Brazil, in three growing seasons.
Six traits were evaluated, including grain yield and popping expansion.
There were highly significant effects for treatments, varieties and mean heterosis for plant and ear heights, and for the others traits the s...
