There have been many crosses made recently. Initial crossing as made at a breeding station in yalta Ukraine. Two varieties were released russhanka and the F2 hybrid nikitaskaya bordovaya. Recently crosses were made in the Midwest by some institute but I forgot the name. The seedlings are growing in Kentucky and a few have been setting fruit for the first time last summer. Those are not released yet... So looking like many hardy Asian persimmon crosses will be released in a few years.
