Description:
HA-R16 (R13b/R12/PlArg) is a F3-derived F4 restorer selection from the cross of RHA 397 and RHA 464. RHA 397 (PI 597374) is an oilseed restorer line harboring the rust resistance gene R13b mapped to linkage group (LG) 13 of the sunflower genome. RHA 464 (PI 655015) is an oilseed restorer line harboring the rust gene R12 mapped to LG11 and a downy mildew gene PlArg mapped on LG1.
