Prima Apple

History: Prima is one the apples developed from the collaborative PRI disease-resistant breeding program run by Purdue University, Rutgers University, and the University of Illinois. It was introduced in 1958 but unfortunately is no longer fully scab resistant due to the fungus evolving to overcome the resistance since then.

Why We Grow It: Another great apple for organic production and excellent for the backyard or farmer’s market sales! This apple is sweet, juicy, and flavourful and boasts several disease resistances, although it should be noted that it is still susceptible to some.
