Such diploid inbred plants are at the heart of Solynta’s strategy to revolutionize potato breeding. They will make it possible to combine traits in commercial varieties with unprecedented certainty, ease, and speed. And the plants will simplify efforts to add desirable traits directly from wild relatives while eliminating their many drawbacks, such as small tubers or poor flavor. Undesirable traits can be bred out of the descendants of a diploid cross through a standard technique called backcrossing.
This seems up @Art’s area of research. I think he was focused on corn…
