Interpretive Summary:

Technical Abstract: The autotetraploid nature of the potato crop hinders breeding progress. In this paper, I describe the advantages of moving to a diploid inbred-hybrid system. This will allow us to reduce the genetic load in potato while assembling desirable combinations of genes. This effort requires us to generate dihaploids and then inbreed them using a mutation in the self-incompatibility system.
