Interpretive Summary: Two maintainer (HA 434 and HA 435) and three restorer (RHA 436 to RHA 438) high-oleic oilseed sunflower germplasm lines were developed cooperatively and released by the USDA-ARS, Fargo, ND, and the North Dakota Agricultural Experiment Station, Fargo, ND. These germplasms are available for use by industry and public researchers to create hybrids, parental lines, or improved germplasms with a mid-oleic (NuSun) or high-oleic fatty acid composition. HA 434 was derived from a cross between a high yielding, high oil content line developed by USDA and a line derived from the original source of high oleic fatty acid, Pervenets, which was developed in Russia. This line incorporates the high-yielding capacity and high oil content with the high oleic characteristic. HA 435 was developed by a mutagenesis program designed to alter the fatty acids of sunflower. Only one plant out of approximately 6800 tested had a high oleic content after the mutagenesis application. The plant was advanced to later generations and selected for high yield and high oil content. RHA 436 to RHA 438 were developed by crossing a line with resistance to all known races of downy mildew found in North America with a high oleic restorer line with high yield and high oil content. The resistance to downy mildew was derived from a wild species of sunflower, Helianthus argophyllus. These lines provide increased genetic diversity to sunflower industry and public improvement programs.

Technical Abstract: Two maintainer (HA 434 and HA 435) and three restorer (RHA 436 to RHA 438) high-oleic oilseed sunflower (Helianthus annuus L.) germplasm lines were developed cooperatively and released by the USDA-ARS, Fargo, ND, and the North Dakota Agricultural Experiment Station, Fargo, ND. These germplasms are available for use by industry and public researchers to create hybrids, parental lines, or improved germplasms with a mid-oleic (NuSun) or high-oleic fatty acid composition.
