(Results of more than 500 will not return images.)
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 651794

| 0 | PI 685015 | 'HA-BSR2' | Helianthus annuus L. | North Dakota, United States | NC7 | | Not Available | 2017 | DEVELOPED | | | | | | Breeding material | HA-BSR2 is a BC2F5 derived BC2F6 oilseed sunflower maintainer line developed for Sclerotinia basal stalk rot (BSR) resistance. The selected line HA-BSR2 was tested for resistance to BSR in inoculated field nurseries across seven environments from 2012 to 2015 in North Dakota and Minnesota, and consistently showed high levels of BSR resistance across all environments. Average disease incidence of basal stalk rot for HA-BSR2 was 4.4%, compared to an average of 36.1% for Cargill 270 (susceptible hybrid), 31.0% for HA 89 (recurrent parent), 19.5% for HA 441 (resistant inbred), and 11.6% for Croplan 305 (resistant hybrid). A whole genome scan was performed using a genotyping-by-sequencing approach to detect the presence of H. petiolaris segments in HA-BSR2. Polymorphic single nucleotide polymorphism markers revealed the presence of introgressed chromosome segments in HA-BSR2 located on linkage group (LG) 8 of the sunflower genome. HA-BSR2 is also homozygously resistant to downy mildew derived from HA 458. HA-BSR2 reached 50% bloom 74 d, grew to 111 cm in height, and seed of HA-BSR2 averaged 85.7% oleic acid from plants grown in a field nursery at Glyndon, MN during the summer of 2015. | 1954407 | PI 685015 |
| 1 | PI 685016 | 'HA-BSR3' | Helianthus annuus L. | North Dakota, United States | NC7 | | Not Available | 2017 | DEVELOPED | | | | | | Breeding material | HA-BSR3 is a BC2F5 derived BC2F6 oilseed sunflower maintainer line developed for Sclerotinia basal stalk rot (BSR) resistance. The selected line HA-BSR3 was tested for resistance to BSR in inoculated field nurseries across seven environments from 2012 to 2015 in North Dakota and Minnesota, and consistently showed high levels of BSR resistance across all environments. Average disease incidence of basal stalk rot for HA-BSR3 was 3.0%, compared to an average of 36.1% for Cargill 270 (susceptible hybrid), 31.0% for HA 89 (recurrent parent), 19.5% for HA 441 (resistant inbred), and 11.6% for Croplan 305 (resistant hybrid). A whole genome scan was performed using a genotyping-by-sequencing approach to detect the presence of H. argophyllus segments in HA-BSR3. Polymorphic single nucleotide polymorphism markers revealed the presence of introgressed chromosome segments in HA-BSR3 located on linkage groups (LGs) 8, 9, 10, and 11 of the sunflower genome. HA-BSR3 is also homozygously resistant to downy mildew derived from HA 458. HA-BSR3 reached 50% bloom 77 d, grew to 115 cm in height, and seed of HA-BSR3 averaged 67.1% oleic acid from plants grown in a field nursery at Glyndon, MN during the summer of 2015. | 1954408 | PI 685016 |

Average disease incidence of basal stalk rot for HA-BSR4 was 0.8%, compared to an average of 36.1% for Cargill 270 (susceptible hybrid), 31.0% for HA 89 (recurrent parent), 19.5% for HA 441 (resistant inbred), and 11.6% for Croplan 305 (resistant hybrid).

The selected line HA-BSR5 was tested for resistance to BSR in inoculated field nurseries across seven environments from 2012 to 2015 in North Dakota and Minnesota, and consistently showed high levels of BSR resistance across all environments. Average disease incidence of basal stalk rot for HA-BSR5 was 1.9%, compared to an average of 36.1% for Cargill 270 (susceptible hybrid), 31.0% for HA 89 (recurrent parent), 19.5% for HA 441 (resistant inbred), and 11.6% for Croplan 305 (resistant hybrid).

Polymorphic single nucleotide polymorphism markers revealed the presence of introgressed chromosome segments in HA-BSR5 located on linkage groups (LGs) 3 and 10 of the sunflower genome.
