| 0 | PI 639165 | HA 442 | Helianthus annuus L. | North Dakota, United States | NC7 |  | | 2005 | DEVELOPED | | | | | | Breeding material | A high-oleic maintainer germplasm line resistant to the imidazolinone herbicide, imazamox, and is available for use by industry and public researchers to create NuSun hybrids, parental lines, or improved germplasms with resistance to this herbicide. The pedigree breeding method was used. The oleic concentration was 851 g kg-1. Height was 125 cm compared with 123 cm for HA 434. Days to flower was 66 d compared with 63 d for HA 434. It is single-headed. | 1675274 | PI 639165 |
| 1 | PI 639166 | RHA 443 | Helianthus annuus L. | North Dakota, United States | NC7 |  | | 2005 | DEVELOPED | | | | | | Breeding material | A high-linoleic, downy mildew resistant restorer germplasm line resistant to the imidazolinone herbicide, imazamox, and is available for use by industry and public researchers to create hybrids, parental lines, or improved germplasms with resistance to this herbicide. The pedigree breeding method was used. It is resistant to the downy mildew races 730, 770, 733, and 304, and the metalaxyl-insensitive strains of downy mildew collected from sunflower production field in North Dakota in 1998. Height was 135 cm compared with 118 cm for RHA 426. Days to flower was 67 compared with 71 for RHA 426. Has genes for fertility restoration of the PET1 cytoplasmic male sterility and has upper stem branching conditioned by a recessive gene. | 1675275 | PI 639166 |
