Abstract
An efficient method of producing hybrid F1 soybean seeds is provided. A male sterile female parent line having a male sterile gene linked to a herbicide resistance gene is crossed with another male fertile soybean variety to produce hybrid soybean seeds.
Claims29
A method of producing hybrid soybean seed comprising:
- a) planting seed of a male sterile female parent line, having a male sterile gene linked to a herbicide resistance gene, adjacent to seed of a male fertile male soybean variety;
- b) allowing male sterile female soybean plants to cross-pollinate with male fertile soybean plants with the aid of pollen-carrying insects;
- c) spraying said plants with said herbicide to kill non-resistant pollen and plants;
- and
- d) harvesting F1 hybrid soybean seed.
A method for the efficient production of seeds capable of growing male fertile F1 hybrid Glycine max plants according to claimy 1, wherein a supplemental pollen source for said pollen-carrying insects is provided in addition to the pollen formed on said male fertile soybean plants of step a) in order to provide ample pollen to support said pollen-carrying insects.
A method of producing soybean F1 hybrid seed comprising:
- a) planting seed of a male sterile female parent, having a male sterile gene linked to a herbicide resistance gene, adjacent to seed of a male-fertile male soybean variety having resistance to a different herbicide;
- b) allowing male sterile female soybean plants to cross with male fertile male plants with the aid of pollen-carrying insects;
- c) spraying said plants after the end of the flowering period with said herbicide to which said female is resistant;
- d) harvesting F1 hybrid soybean seed.
A method to create a blend of hybrid and variety seed comprising:
- a) planting seed of a male sterile female parent line, having a male sterile gene linked to a herbicide resistance gene, adjacent to seed of a male fertile male soybean variety;
- b) allowing male sterile female soybean plants to cross-pollinate with male fertile soybean plants with the aid of pollen-carrying insects;
- and
- c) harvesting a blend of hybrid and selfed soybean seed.
