ABSTRACT:
This invention relates to a novel semi-dwarf hybrid sunflower (Helianthus annuus var. macrocarpus (DC.) Ckll. (herein H. annuus) seed and a method of producing the hybrid seed. The hybrid sunflower seed upon growth yields a semi-dwarf sunflower plant having a reduced internode length. The hybrid seed is produced by cross pollinating a pair of parent plants P.sub.1 and P.sub.2 wherein, in at least one parent substantially all pollen is nonfunctional and at least one parent has gametes with nuclei carrying at least one dominant gene for reduced internode length.
