There are some significant cases of heterosis and of inbreeding depression, but
the percentages are extremely small in comparison with similar characters in
crossbreeding species. Robinson, Mann, and Comstock (1954) reported slightly

This was least in straw diameter (20% excess in Ft diploids, 24% in F1 tetraploids
) and most in the composite characters: straw weight (200% in F1 diploids, 144%
in Fi tetraploids), kernel yield on the largest ear (132% in F1 diploids, 324%, ...
