Description:
HA-DM12 (Pl8/PlArg/R12) is a F3-derived F4 restorer selection from the cross of RHA 340 and RHA 464. RHA 340 (PI 518778) is an oilseed restorer line harboring the downy mildew (DM) gene Pl8 mapped on LG13. RHA 464 (PI 655015) is an oilseed restorer line harboring the DM gene PlArg mapped to LG1 of the sunflower genome and the rust gene R12 mapped to LG11, respectively.
