WineCrisp, formerly known as Coop31, is a modern disease-resistant variety developed by the Universities of Prudue, Rutgers and Illinois and introduced in the 1990s.
The parentage is complex, but unusually for a modern disease-resistant variety it incorporates Cox's Orange Pippin as one of its grandparents. Cox is known for the excellence of is flavor but is not particularly disease-resistant. Jonathan, an old American variety which is well-regarded for flavor is also featured in the parentage.
Resistance to scab is taken care of by the well-established technique of using the crab-apple Malus floribunda in the parentage, along with variations of Rome Beauty, an apple noted for its general disease resistance and good cropping.
Flavor, as well as disease-resistance, was clearly a goal in the development of WineCrisp. As the name suggests, this is a crisp apple with a fruity flavor.
Visually WineCrisp resembles Jonathan and Delicious.
