Levels of hybrid vigor for earliness, height, three components of yield, and grain yield were examined in the F1 and F2 generations of a diallel cross of seven varieties selected from hard red, soft white, and soft red winter wheats. Entries planted in hills showed little interaction with seeding rates of 3 to 15 plants per 930 cm2 (1 ft2), but the degree of hybrid vigor tended to be greater for hill seeding than for normal seeding.
