Narrative
HA-DM16 (Pl38Pl38) is an improved oilseed derivative of Rf PRA-417 (PI 596749) with resistance to downy mildew (DM). Rf PRA-417 is a BC1F2 bulk from an interspecific cross of cytoplasmic male sterile (CMS) HA 89*2/PRA-417 released as a male fertility restorer line in 1991. The CMS HA 89 was developed by substituting the nuclear genome of HA 89 into the background of a wild annual species H. petiolaris (CMS PET1). PRA-417 is a wild H. praecox subsp. runyonii accession. Initial DM screening with P. halstedii race 734 revealed that Rf PRA-417 was segregating for DM infection. Six resistant plants from the Rf PRA-417 population of 58 plants tested were selected and self-pollinated to the next generation. The progeny tests of the selected plants revealed that three, 19-06-3, 19-06-4, and 19-06-5 (BC1F3) were homozygously resistant to DM infection. The DM R gene Pl38 from the wild H. praecox PRA-417 has been genetically mapped to sunflower chromosome 2. The BC1F3-derived HA-DM16 is homozygous for the Pl38 gene verified by DNA markers and immune to the most prevalent and virulent P. halstedii races, 700, 707, 714, 730, 734, 770, and 776. Plant height of HA-DM16 was 158 cm compared to 135 cm for HA 89, and flowered in 68 days after planting the same as HA 89 in the field nursery at Glyndon, MN during the summer of 2021
