摘要
The present invention relates to the production of hybrid wheat and triticale plants and seeds via the employment of genetically-controlled cytoplasmic male sterility (CMS) and genetically-controlled fertility restoration. The genetically-controlled cytoplasmic sterility mechanism according to the present system and method utilizes genes conferring CMS in the presence of Aegilops squarrosa cytoplasm, and for restoring fertility to wheat and triticale plants having Aegilops species cytoplasm. The invention also relates to the use of specific, induced mutant sources of tolerance to herbicides for destroying the seed producing ability of the male fertility restorer parent after pollination has completed, to achieve essentially 100% hybrid seed reproduction from a mixture of a CMS male sterile line and a pollen fertility restorer line.
