Outcrossing of opaque‐2 and floury‐2 single crosses of corn, Zea mays L., to the same mutant but unrelated genotype, significantly increased kernel weight and weight of grain per ear of opaque‐2 and floury‐2 single crosses, and this increase was greater than in the normal counterparts. When sibbed, opaque‐2 and floury‐2 kernels had heavier germs than the normal kernels. Outcrossing also increased weight of endosperm in opaque‐2, floury‐2, and normal kernels; and germ weight in opaque‐2 and normal kernels. Protein and lysine content were apparently not affected by outcrossing.
