Abstract

NP31 and NP32 sudangrass [Sorghum bicolor (L.) Moench] [formerly S. sudanense (Piper) Staph] (Reg. no.GP-239 and GP-240; PI 535775 and PI 535776), two populations developed cooperatively by the USDA-ARS and the Nebraska Agricultural Research Division, were released in April 1989. These populations are potential sources of low-dhurrin germplasm for public and private sudangrass breeding programs. NP31 also contains the ms₃ gene for genetic male sterility and NP32 may be a source of sudangrass B-lines.
