I have had inside knowledge of quite a few parent stocks used in making F-1 hybrids over the last 40 years. Potato leaf female lines were starting to be the norm and many times when I selfed the hybrids I found proof of the alleged or given parent(s). Early Cascade is another line has a female potato leaf parent. I will likely go to my grave with pedigree data since I don't want to disclose proprietary info.
