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

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 670043 | HA-R10 | Helianthus annuus L. | North Dakota, United States | NC7 | | | 2014 | DEVELOPED | | | | | | Breeding material | HA-R10 is a BC3F3-derived BC3F4 confection maintainer line resistant to the most predominant North American races of rust (caused by Puccinia helainthi Schw.). The rust resistance gene in HA-R10 was transferred from oilseed HA-R2 by backcross and pedigree selections. This gene was named R5 and mapped to linkage group 2 of sunflower. The evaluation of rust resistance and DNA markers linked to the R5 gene on HA-R10 indicates that this line is homozygous for the gene R5. Plant height of HA-R10 was 100 cm compared to 103 cm for CONFSCLB1 in the Fargo, ND, field nursery during the summer of 2012. | 1917125 | PI 670043 |
| 1 | PI 670044 | HA-R11 | Helianthus annuus L. | North Dakota, United States | NC7 | | | 2014 | DEVELOPED | | | | | | Breeding material | HA-R11 is a BC4F3-derived BC4F4 confection restorer line resistant to the most predominant North American races of rust (caused by Puccinia helainthi Schw.). The rust resistance gene in HA-R11 was transferred from oilseed HA-R3 by backcross and pedigree selections. This gene was named R4 and mapped to linkage group 13 of sunflower. The evaluation of rust resistance and DNA markers linked to the R4 gene on HA-R11 indicates that this line is homozygous for the gene R4. Plant height of HA-R11 was 89 cm compared to 83 cm for CONFSCLR5 in the Fargo, ND, field nursery during the summer of 2012. | 1917126 | PI 670044 |
