Interpretive Summary: Twenty-two sorghum male-sterile genetic stocks were jointly released by the ARS; and the Agricultural Research Division, Institute of Agriculture and Natural Resources University of Nebraska. These genetic stocks are based on elite sorghum inbred lines and in a nuclear gene (ms3) that greatly simplifies crossing of lines by eliminating the need to manually remove the emale portion of the tiny and numerous sorghum flowers (anthers) to prevent pollination. They also permit the development of random mating populations that can be used in the improvement of sorghum. Both uses should enhance industry's ability to develop new superior sorghum hybrids.

Technical Abstract: Twenty-two forage sorghum [Sorghum bicolor (L.) Moench] male-sterile genetic stocks were jointly released by the USDA-ARS; and the Agricultural Research Division, Institute of Agriculture and Natural Resources, University of Nebraska. These genetic stocks are based on elite sorghum inbred lines, contain the ms3, and closely resemble their elite recurrent parents. These genetic stocks significantly broaden the existing base of elite inbred lines with ms3. They have immediate application for basic research involving ms3. They also may be used as a base to directly synthesize random mating populations, or for integration of superior genes from other genetic sources into agronomically proven lines using population breeding techniques.
