Abstract

An improved cytoplasmic male sterile line and improved production of hybrid soybean plants which utilizes the control of a single nuclear restorer gene to impact sterility. A cytoplasmic male sterile soybean plant is provided, wherein fertility is restored through the introduction of a dominant allele at a nuclear restorer gene locus. Maintenance of the cytoplasmic male sterile soybean line is achieved through cross pollination with a male fertile isoline wherein the isoline has a fertile cytoplasm gene and recessive alleles at a nuclear restorer gene locus. The cytoplasmic male sterile line can be used as a female in the production of hybrid soybean plants when cross-pollinated with a male sterile restorer line having dominant restorer allele at the nuclear restorer gene loci. The resulting seeds are harvested from the female plant and can be planted to grow male fertile F1 plants.
