Identification, Elucidation and Deployment of a Cytoplasmic Male Sterility System for Hybrid Potato.

ABSTRACT: Recent advances in diploid F₁ hybrid potato breeding rely on the production of inbred lines using the S-locus inhibitor (Sli) gene. As a result of this method, female parent lines are self-fertile and require emasculation before hybrid seed production. The resulting F₁ hybrids are self-fertile as well and produce many undesirable berries in the field. Utilization of cytoplasmic male sterility would eliminate the need for emasculation, resulting in more efficient hybrid seed production and male sterile F₁ hybrids. We observed plants that completely lacked anthers in an F₂ population derived from an interspecific cross between diploid S. tuberosum and S. microdontum. We studied the antherless trait to determine it
