Interpretive Summary: Four sunflower germplasms high in linoleic acid content were developed and released by the USDA-ARS, Fargo, ND, and the North Dakota Agricultural Experiment Station, Fargo, ND. HA 413 and HA 414 are oilseed maintainer germplasms, and RHA 415 and RHA 416 are oilseed restorer germplasms. These germplasms produced hybrids which averaged 6 to 8 % higher in linoleic acid content than normal check hybrids presently grown in the United States and were more stable across different environments. The germplasms were derived by crossing USDA inbred lines with plants selected from a high linoleic acid sunflower population obtained from the Department of Primary Industries, Queensland, Australia. The advantage of high linoleic hybrids over the traditional check hybrids was 8.3 % in North Dakota and 19.2 % in Texas, indicating stability of linoleic acid content in these hybrids over environments. The four sunflower germplasms are adapted to all sunflower production areas of the United States.
