NP25 sudangrass [Sorghum bicolor (L.) Moench] (Reg. no. GP-180), a low-dhurrin, random-mating population that carries the ms3 gene for genetic male sterility, was developed cooperatively by USDA-ARS and the Nebraska Agricultural Research Division and released in April 1984. Plants of NP25 are leafy and fine-stemmed, 160 to 170 cm in height with dry stalks (white midrib), tan plant color, sienna glumes, and brown pericarp. NP25 restores fertility to hybrids when crossed to male steriles with A1 cytoplasm.
