Crosses between inbreeds form different heterotic groups result in vigorous F1 hybrids with significantly more heterosis than F1n hybrids from inbreeds within the same heterotic group or pattern. Heterotic groups are created by plant breeders to classify inbred lines, and can be progressively improved by reciprocal recurrent selection.
