Description:
HA-R14 (R4/R12/PlArg) is a F3-derived F4 maintainer selection from the cross of HA-R3 and RHA 464. HA-R3 (PI 650754) is an oilseed maintainer line harboring the rust resistance gene R4 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 to LG1.
