Narrative
HA-DM8 is a BC2F5-derived BC2F6 oil-type maintainer selection from the cross of HA 89*2//NMS HA 89/Helianthus argophyllus accession PI 494576. HA 89 (PI 599773) is an oilseed maintainer line susceptible to DM released by USDA and the Texas Agricultural Experiment Station in 1971, while the nuclear male sterile (NMS) HA 89 (PI 559477) is a mutation of HA 89, genetically similar to HA 89, but possessing a single recessive male sterile gene ms9 released by USDA in 1992. The wild annual Helianthus argophyllus accession (PI 494576) originally collected in Texas in 1984 was identified as resistant to the most virulent DM race 777 in 2005. HA-DM8 was developed using the backcross breeding method and DNA marker-assisted selection for the Pl35 DM resistance gene introgressed from wild H. argophyllus accession PI 494576. The cross between NMS HA 89 and PI 494576 was initially made in 2012 and the selected resistant F1 plants were backcrossed twice to HA 89. A total of 62 HA-DM8 plants, along with the recurrent parent HA 89 were tested with P. halstedii race 734 in the greenhouse, and no susceptible plants were observed, indicating that the BC2F5-derived HA-DM8 is homozygous resistance to DM. Four SNP markers, NSA_002131, NSA_002798, NSA_002851, and NSA_009758 diagnostic for Pl35 were used to test the 62 resistant HA-DM8 plants. All HA-DM8 plants showed Pl35 marker alleles different from the recurrent parent HA 89, confirming the presence of the Pl35 gene in HA-DM8. HA-DM8 is immune to the most predominant and virulent DM races currently identified in the United States and Europe. Plant height of HA-DM8 was 109 cm compared to 95 cm for HA 89, and flowers in 90 days after planting compared to 85 days for HA 89 in the field nursery at Glyndon, MN during the summer of 2019.

Description:
HA-DM8 is a BC2F5-derived BC2F6 oil-type maintainer selection from the cross of HA 89*2/NMS HA 89/Helianthus argophyllus accession PI 494576. HA 89 (PI 599773) is an inbred maintainer line susceptible to downy mildew. The H. argophyllus accession (PI 494576) was originally collected in Texas in 1984, and is resistant to new virulent races of downy mildew.
