Description:
HA-R17 (R13b/R15) is a F3-derived F4 restorer selection from the cross of RHA 397 and HA-R8. 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. HA-R8 (PI 607511) is an oilseed restorer line harboring the rust gene R15 mapped to LG8.
