| 0 | PI 698193 | 'HA-R14' | Helianthus annuus L. | North Dakota, United States | NC7 | | Not Available | 2021 | DEVELOPED | | | | | | Cultivar | HA-R14 is a F3-derived F4 maintainer selection from the cross of HA-R3 and RHA 464. HA-R3 (PI 650754) is an oilseed maintainer line resistant to rust released by USDA and the North Dakota Agricultural Experiment Station in 1985. The rust resistance gene (R gene) in HA-R3 was named R4 and mapped to linkage group (LG) 13 of the sunflower genome. RHA 464 (PI 655015) is an oilseed restorer line released by USDA-ARS and the North Dakota Agricultural Experiment Station in 2010 resistant to all North America rust and downy mildew (DM) races identified so far. The DM and rust resistance genes in RHA 464 were named PlArg and R12 and mapped to LGs 1 and 11 of the sunflower genome, respectively. HA-R14 was developed by the pedigree breeding method and DNA marker-assisted selection for pyramiding of the rust R-genes R4 from HA-R3 and R12 from RHA 464 and the DM R gene PlArg from RHA 464. The F3-derived HA-R14 is homozygous for both the rust R genes, R4 and R12, and the DM R gene PlArg verified by DNA markers, and is resistant to all known races of North American sunflower rust and all known races of the pathogen causing DM. | 2113460 | PI 698193 |
| 1 | PI 698194 | 'HA-R15' | Helianthus annuus L. | North Dakota, United States | NC7 | | Not Available | 2021 | DEVELOPED | | | | | | Cultivar | HA-R15 is a F3-derived F4 maintainer selection from the cross of HA-R2 and RHA 464. HA-R2 (PI 650753) is an oilseed maintainer line resistant to rust released by USDA and the North Dakota Agricultural Experiment Station in 1985. The rust resistance gene in HA-R2 was named R5 and mapped to LG2 of the sunflower genome. RHA 464 (PI 655015) is an oilseed restorer line released by USDA-ARS and the North Dakota Agricultural Experiment Station in 2010 resistant to all North America rust and downy mildew (DM) races identified so far. The DM and rust resistance genes in RHA 464 were named PlArg and R12 and mapped to LGs 1 and 11, respectively. HA-R15 was developed by the pedigree breeding method and DNA marker-assisted selection for pyramiding of the rust R-genes R5 from HA-R2 and R12 from RHA 464 and the DM R gene PlArg from RHA 464. The F3-derived HA-R15 is homozygous for both the rust R genes, R5 and R12, and the DM R gene PlArg verified by DNA markers, and is resistant to all known races of North American sunflower rust and all known races of the pathogen causing DM. | 2113461 | PI 698194 |
| 2 | PI 698195 | 'HA-R16' | Helianthus annuus L. | North Dakota, United States | NC7 | | Not Available | 2021 | DEVELOPED | | | | | | Cultivar | HA-R16 is a F3-derived F4 restorer selection from the cross of RHA 397 and RHA 464. RHA 397 (PI 597374) is an oilseed restorer line resistant to rust released by USDA and the North Dakota Agricultural Experiment Station in 1997. The rust resistance gene in RHA 397 was named R13b and mapped to LG13 of the sunflower genome. RHA 464 (PI 655015) is an oilseed restorer line released by USDA-ARS and the North Dakota Agricultural Experiment Station in 2010 resistant to all North America rust and downy mildew (DM) races identified so far. The DM and rust resistance genes in RHA 464 were named PlArg and R12 and mapped to LGs 1 and 11, respectively.

| 3 | PI 698196 | 'HA-R17' | Helianthus annuus L. | North Dakota, United States | NC7 | | | 2021 | DEVELOPED | | | | | | Cultivar | HA-R17 is a F3-derived F4 restorer selection from the cross of RHA 397 and HA-R8. RHA 397 (PI 597374) is an oilseed restorer line resistant to rust released by USDA and the North Dakota Agricultural Experiment Station in 1997. The rust resistance gene in RHA 397 was named R13b and mapped to LG13 of the sunflower genome. HA-R8 (PI 607511) is an oilseed restorer line resistant to rust released by USDA and the North Dakota Agricultural Experiment Station in 2001. The rust resistance gene in HA-R8 was named R15 and mapped to LG8. HA-R17 was developed by the pedigree breeding method and DNA marker-assisted selection for pyramiding of the rust R-genes R13b from RHA 397 and R15 from HA-R8. The F3-derived HA-R17 is homozygous for both the rust R genes, R13b and R15, verified by DNA markers, and is resistant to all known races of North American sunflower rust | 2113463 | PI 698196 |
