Progress in Research on Apomixis and Its Transfer to Major Grain Crops

Conference paper

Abstract

Seeds are generally considered a product of sexual reproduction, and yet seeds are produced asexually by hundreds of species of higher plants. Apomixis--a term that originally described all types of asexual reproduction, including vegetative propagation--is now used to denote asexual reproduction by means of seeds. This type of reproduction has long been regarded merely as a botanical curiosity and, in his review, Stebbins (1950) stated that this process was controlled by complex interactions between recessive genes, leaving little hope for breeders ever making practical use of apomixis. The transfer of such a characteristic from a wild species to its cultivated relative was unthinkable.
