According to the US Apple Association website it is one of the fifteen most popular apple cultivars in the United States. Apples can be preserved by short, medium or long-term storage.

Abelian variety of CM-type Abelian variety of CM-type In mathematics, an abelian variety "A" defined over a field "K" is said to have CM-type if it has a large enough commutative subring in its endomorphism ring End("A"). The terminology here is from complex multiplication theory, which was developed for elliptic curves in the nineteenth century. One of the major achievements in algebraic number theory and algebraic geometry of the twentieth century was to find the correct formulations of the corresponding theory for abelian varieties of dimension "d" > 1. The problem is at a deeper level of abstraction, because it is much harder to
