Technical Abstract: In most regions of the world, potato cultivars are tetraploid. However, complexities due to tetraploid genetics have slowed breeding progress and limited the implementation of breeding strategies commonly used in other major crops. We are developing diploid genetics resources, including partially inbred mapping populations and recombinant inbred lines, using the dominant self-incompatibility inhibitor, Sli. In addition, we have created diploid interspecific hybrids with yields comparable to tetraploid cultivars. This has led us to pursue the idea of breeding cultivars at the diploid level. Toward this end, we have introgressed the Sli gene into diploid specialty clones to create populations for a participatory breeding project in which growers can select custom cultivars for their operations.
