Narrative
HA-DM7 is a BC2F3-derived BC2F4 oilseed maintainer selection from the cross of HA 89*2/NMS HA 89/Helianthus argophyllus accession PI 494578. HA 89 (PI 599773) is an inbred maintainer line susceptible to downy mildew (caused by Plasmopara halstedii) released by USDA and the Texas Agricultural Experiment Station in 1971. The nuclear male sterile (NMS) HA 89 (PI 559477) induced by streptomycin treatment of HA 89 possesses a single recessive ms9 male sterility gene released by the UDSA and the North Dakota Agricultural Experiment Station, Fargo, ND in 1990. The H. argophyllus accession (PI 494578) was originally collected in Texas in 1984, and is resistant to new virulent races of downy mildew. HA-DM7 was developed by the backcross breeding method and DNA marker-assisted selection for the Pl20 downy mildew resistance gene introgressed from wild H. argophyllus (PI 494578). The cross between NMS HA 89 and PI 494578 was made in 2012 and the selected resistant F1 plants were backcrossed twice to HA 89. The BC2F3-derived HA-DM7 is homozygous for the Pl20 gene verified by DNA markers and greenhouse downy mildew screening. HA-DM7 is immune to the most predominant and virulent races of downy mildew currently identified in the United States and Europe. Plant height of HA-DM7 was 149 cm compared to 121 cm for HA 89 and flowers 75 days after planting compared to 65 days for HA 89 in the field nursery at Glyndon, MN during the summer of 2017.
