The breeding code XF4991 corresponds to the commercial sunflower hybrid PR64G46, developed by breeders at Pioneer. In official registers and variety registration documents, this code is used to identify the specific hybrid.
In open agronomic references, detailed plant characteristics, such as height, disease resistance indicators, or oil quality parameters, are provided exclusively under the commercial name PR64G46, as the working designation XF4991 is not intended for use by end consumers.
