Abstract

NP36 and NP37 grain sorghum [Sorghum bicolor (L.) Moench] (Reg. no. GP-244 and GP-245; PI 535780 and PI 535781), two random-mating populations of grain sorghum, were developed cooperatively by the USDA-ARS and the Nebraska Agricultural Research Division and were released in April 1989. Both populations were selected for reduced dhurrin content, and they have potential value as sources of A- and B-lines of grain sorghum for use in producing low-dhurrin sorghum-sudangrass hybrids. NP37 also contains the bmr-6 gene for brown midribs and, therefore, may be useful in producing sorghum-sudangrass or forage sorghum hybrids with brown midribs.
