Heterosis in Barley1

  1. J. E. Grafius2

Synopsis

Synopsis

Evidence was presented that genes for yield per se do not exist in barley. Hence yield is an artifact. If there are no genes per se for yield, there can be no dominance effects due to yield genes, or for that matter no over-dominance of yield genes or heritability of yield. F1 vigor was shown to be due to epistasis. A large share of the F1 vigor in this experiment was shown to be fixable in a true breeding form.
