RESEARCH on heterosis in barley, Hordeum vulgare L., has been accelerated by Wiebe's plan for production of hybrid barley utilizing a gene-phytocide reaction. It is too early to predict whether or not it will be possible to exploit heterosis in the production of barley. The possibility of hybrid barley, however, makes research on combining ability and heterosis imperative. Little is known about heterosis and combining ability pertaining to grain yield and nothing has been reported on forage yield of barley hybrids. Suneson and Immer have reported that grain yields of some barley hybrids exceed their respective better-yielding parents. Hagberg working with 17 barley hybrids observed no heterosis for grain yield. He did report evidence of heterosis for total plant weight of F! hybrids which could indicate that hybrid vigor could be manifested in forage production.
