Registration of three maintainer (HA 456, HA 457, and HA 412 HO) high-oleic oilseed sunflower germplasms. Crop Science. 46:2728. Interpretive Summary: Three maintainer (HA 456, HA 457, and HA 412 HO) high-oleic oilseed sunflower germplasms were developed and released by the USDA-ARS, Fargo, ND, and the North Dakota Agricultural Experiment Station, Fargo, ND. These germplasms have been selected for their high oleic acid content, agronomic characteristics, and oil quantity. HA 456 is an F6-derived F7 maintainer line advanced by pedigree selection from the cross HA 434/S-16 YU. The S-16 YU breeding line was obtained through a germplasm exchange with Dr. Dragan Skoric, Institute of Field and Vegetable Crops, Novi Sad, Serbia, in 1992. HA 457 is an F6-derived F7 maintainer line advanced by pedigree selection from the cross HA 434//HA 821/Dussol. Dussol (Ames 22499) is a short-statured maintainer line released by INRA, Clermont-Ferrand, France, in 1995. HA 412 HO is a BC4F3 germplasm line derived from the pedigree HA 412*5/HA 434. The objective of this backcross was to convert the traditional oil line (high-linoleic acid) HA 412 to a high-oleic acid line to be used to produce NuSun(R) or high-oleic hybrids with Sclerotinia head and stalk rot tolerance. The recurrent parent HA 412 (PI 603993) is a Sclerotinia head and stalk rot tolerant line released by USDA and the North Dakota Agricultural Experiment Station in 1995. Plants of HA 456, HA 457, and HA 412 HO grown in the 2004 breeding nursery at Fargo, ND, averaged 838, 835, and 834 g kg-1 oleic acid, respectively, compared to 847 g kg-1 for HA 434. HA 456, HA 457, and HA 412 HO are single-headed. These germplasms are available for use by industry and public researchers to create hybrids, parental lines, or germplasms with a mid-oleic (NuSun®) (>550 and <700 g kg-1 oleic acid) or high-oleic (>800 g kg-1) fatty acid concentration in the oil. Technical Abstract: Three maintainer (HA 456, HA 457, and HA 412 HO) high-oleic oilseed sunflower (Helianthus annuus L.) germplasms were developed and released by the USDA-ARS, Fargo, ND, and the North Dakota Agricultural Experiment Station, Fargo, ND. These germplasms have been selected for their high oleic acid content, agronomic characteristics, and oil quantity.

The objective of this backcross was to convert the traditional oil line (high-linoleic acid) HA 412 to a high-oleic acid line to be used to produce NuSun(R) or high-oleic hybrids with Sclerotinia [caused by Sclerotinia sclerotiorum (Lib.) de Bary] head and stalk rot tolerance. The recurrent parent HA 412 (PI 603993) is a Sclerotinia head and stalk rot tolerant line released by USDA and the North Dakota Agricultural Experiment Station in 1995. Plants of HA 456, HA 457, and HA 412 HO grown in the 2004 breeding nursery at Fargo, ND, averaged 838, 835, and 834 g kg-1 oleic acid, respectively, compared to 847 g kg-1 for HA 434.
