This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as

PI 651650
When searching a range of accessions, use the Advanced Search tab with the Accession Identifier Range criterion.
The more information you provide, the better the search will be.

| 0 | PI 639162 | RHA 439 | Helianthus annuus L. | North Dakota, United States | NC7 |  | | 2005 | DEVELOPED | | | | | | Breeding material | A high-linoleic, sclerotinia head rot tolerant restorer germplasm line available for use by industry and public researchers to create hybrids, parental lines, or germplasms with improved sclerotinia head rot tolerance. The pedigree breeding method was used. Sclerotinia tolerance was selected by evaluating testcross hybrids that were artificially inoculated under irrigation. Height was 140 cm compared with a height of 138 cm for RHA 377. Days to flower was 63 d compared with 62 d for RHA 377. Has fertility restoration factors for the PET1 cytoplasmic male sterility and has upper-stem branching conditioned by a recessive gene. | 1675271 | PI 639162 |

The pedigree breeding method was used. Sclerotinia tolerance was selected by evaluating testcross hybrids that were artificially inoculated under irrigation. Height was 150 cm compared with a height of 138 cm for RHA 377. Days to flower was 67 d compared with 62 d for RHA 377. Has fertility restoration factors for the PET1 cytoplasmic male sterility and has upper-stem branching conditioned by a recessive gene. | 1675272 | PI 639163 |
| 2 | PI 639164 | HA 441 | Helianthus annuus L. | North Dakota, United States | NC7 |  | | 2005 | DEVELOPED | | | | | | Breeding material | Maintainer line derived from a cross between between the HA412 (PI 603993) and SD (received by germplasm exchange with Dr. Felicity Vear, Station d Amelioration des Plantes, INRA, Clermont-Ferrand, France). The pedigree breeding method was used in development. Sclerotinia tolerance of this line was selected by evaluating testcross hybrids that were artificially inoculated under mist irrigation. Height was 160 cm compared with a height of 145 cm for HA 412. Days to flower of HA 441 was 61 d compared with 56 d for HA 412. | 1675273 | PI 639164 |
