Last i read it is available as a commercial variety only. It was developed by Cornell so they will control the licensing and distribution. You might contact them to see if the status has changed.

Meanwhile there are several PM resistant varieties available although the disease could still develop on any of them given the right conditions. Consider Dunja, Tigress or Plato.

I was also going to suggest Dunja, since I noticed it in the Johhny's catalog earlier today. Never have grown it, just noticed it was PM resistant.

Here is a list of some PM resistant varieties.
