Prima is a crisp textured, tart apple primarily used for eating fresh. This cultivar is one of many developed by PRI, a disease resistant apple breeding program, which is a cooperative among Purdue University, Rutgers University, and the University of Illinois.

The difference between apples and crabapples is the size of the fruit. If the fruit is 2 inches or greater, it is considered an apple; if less than 2 inches, it is considered a crabapple. While apple fruit trees are generally grown commercially and in quantity as a crop, they can also be grown in the home garden. Special attention to pollination, disease/pest vigilance, and pruning may be required for the trees to thrive and fruit in the home environment. Although apple fruit trees produce attractive flowers, hybridizing efforts focus on fruit characteristics such as taste, texture, and storage capacity and on disease resistance. Since apple cultivars are usually grafted onto a root stock, it is often possible to select a tree for the home garden that is smaller than its commercial counterpart. Apple trees produce best fruiting when they are between 10 and 30 years of age.
