0PI 655009HA 458Helianthus annuus L. North Dakota, United StatesNC7ACHENES2008DEVELOPEDGenetic materialBC3F5-derived BC3F6 maintainer genetic stock. Resistant to the North American races 730, 733, and 770 and to the French race 304. Inheritance studies indicated that the resistance was controlled by a single, dominant gene and preliminary molecular marker comparisons indicated that this resistance gene was different from both the PI6 and PI8 genes. Averaged 865 g kg-1 oleic fatty acid in seed from plants grown in the Fargo, ND field nursery during the summer of 2005.1786204PI 655009

Resistant to the North American races 730, 733, and 770, but is susceptible to the French race 304.

2PI 655011HA 460Helianthus annuus L. North Dakota, United StatesNC7ACHENES2008DEVELOPEDGenetic materialBC3F3-derived BC3F4 maintainer genetic stock. Resistant to the North American races 730, 733, and 770 and to the French race 304. Averaged 888 g kg-1 oleic fatty acid in seed from plants grown in the Fargo, ND field nursery during the summer of 2005. The first maintainer genetic stock released to combine the high oleic fatty acid characteristic with the PI8 downy mildew resistance.1786206PI 655011
