An inbred sunflower line, designated CN1229R, the plants and seeds of the inbred sunflower line CN1229R, methods for producing a sunflower plant, either inbred or hybrid, produced by crossing the inbred sunflower line CN1229R with itself or with another sunflower plant, and hybrid sunflower seeds and plants produced by crossing the inbred line CN1229R with another sunflower line or plant and to methods for producing a sunflower plant containing in its genetic material one or more transgenes and to the transgenic sunflower plants produced by that method. This invention also relates to inbred sunflower lines derived from inbred sunflower line CN1229R, to methods for producing other inbred sunflower lines derived from inbred sunflower line CN1229R and to the inbred sunflower lines derived by the use of those methods.
