Also known as: Co-Op 38. Co-Op 17 x Golden Delicious. Developed by PRI (Purdue, Rutgers, Illinois Co Op) in 1994.
The apple is conic-round, medium large, and a deep uniform greenish yellow. Flesh is hard, very crisp and breaking, flavor intense and memorable. Both sugar and acid levels are high (soluble solids seldom below 17%), the balance slightly favoring tartness at harvest, then mellowing in storage. The complex flavor profile makes it extremely valuable in cider production. Length of storage almost without parallel, in excess of six months, good texture out of a household refrigerator as late as July or August.
GoldRush is field immune to scab, highly resistant to powdery mildew, susceptible to cedar-apple rust, moderately resistant to fire blight. Frut ripens late October through mid November, but extremely high sugar levels help protect from freezing. The tree will survive temperatures down to -22 degrees, and should be safe for up to USDA plant hardiness zone 5. GoldRush's disease resistance and easy growing habits make it a solid choice for organic growers.
Ed Fackler, fruit consultant in Indiana says: "It's one of the easiest things to grow in my life.The tree sets a heavy crop but is easy tothin to achieve good-sized fruit. The tree is naturally small. This is just a moron-proof apple." A royalty of $1.00 is added to the base price of this tree.
