I was reading a partial abstract about breeding for red or purple flesh in potatoes, and it stated that purple-fleshed progeny were obtained from red x white crosses where the white-fleshed parent harbored the P pigment gene in juxtaposition with the nulliplex recessive state of the I gene (i.e.,iiii). 
Do any of the online potato vendors like Ronniger's have a white potato with such a gene juxtaposition? It seems exciting to be able to breed a purple potato from a red x white. Can a purple potato be grown from a red x red?
Btw, the Purple Viking must have some interesting genetics in order to have both red and purple skin. I wonder what types of progeny would result crossing Viking Purple with Skagit Valley Beet or Azul Toro or perhaps crossing Viking Purple with Cranberry Red.
