Delblush -- has already gained commercial acceptance in Europe where it is known as Tentation. Ripens a tad later than Golden Delicious. Tree availability is like to be limited.
Enterprise -- is a first generation scab-resistant apple from the PRI breeding program. Although attractive, it matures late, has a thick skin, and flavor is not altogether pleasant. Despite being around for awhile, it has gained very limite acceptance -- there are better choices. Tree is very vigorous.
