Malus domestica 'GoldRush'
GoldRush is a very fine, high quality disease resistant golden apple with a pretty blush. It is one of the latest harvesting apples, so may not ripen properly in many northern areas. However, letting it hang as long as possible and storing for a while before eating will allow it to mellow. It is very firm, crisp and juicy. Tart at harvest it will develop a very rich, well balanced flavor after a few weeks of storage. It stores very well.
GoldRush was called Co-op 38 when in the disease resistant, cooperative apple breeding program run by Purdue, Rutgers, and Illinois. It was named and introduced in 1973.
