Description:
HA-DM13 (Pl17/PlArg/R12) is a F3-derived F4 maintainer selection from the cross of HA 458 and RHA 464. HA 458 (PI 655009) is an oilseed maintainer line harboring the downy mildew (DM) resistance gene Pl17 mapped to linkage group (LG) 4 of the sunflower genome. 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.
