Abstract
The utilization of heterosis in F1 hybrids is generally the ultimate aim in forage breeding since such hybrids usually are more productive than cross-pollinated, selfpollinated, or synthetic varieties. In breeding .sudangrass, Sorghumv ulgate var. sudanense Hitchc., attention has been directed toward reducing the hydrocyanic acid content, increasing sweetness, and improving yield, disease resistance, leafiness, and other agronomic characteristics. Several workers (1, 4, 8) have presented evidence for increasing forage production by utilizing hybrid vigor in sudangrass. Recently, Burton (2) suggested the use of 1 hybrids in sudangrass; however, this has not been feasible due to the lack of a good source of male-sterility in this species. The research described here investigated the possibilities of developing a hybrid sudangrass. Procedures for obtaining and increasing a cytoplasmic male-sterile sudangrass, the requirements for maintaining .sterility, and the utilization of the sterile in the production of F1 hybrid sudangrass seed are described. The performance of an F~ hybrid also.............
