CYTOPLASMIC male-sterility has been used in the commercial production of hybrid seed corn for a number of years. More recently it has been used in hybrid grain sorghum seed production. Since sudangrass (Sorghum vulgare var. sudanense Hitch.) has a perfect flower and is often self pollinated, a male-sterile line is essential for the commercial production of hybrid sudangrass seed. Although only one cytoplasmic male-sterile sudangrass has been reported, it is likely that cytoplasmic male-sterility occurs more frequently than has been realized, and a systematic search may lead to the location of more promising types. The mode of inheritance is always important in evaluating any source of sterility. With these facts in mind, an inheritance study on the interaction of cytoplasm with malesterility factors in sudangrass was conducted.
