Abstract

'Prima' is a new, red apple cultivar introduced from a cooperative breeding program carried out by the Agricultural Experiment Stations of Illinois, NEw Jersey, and Indiana, and informally cooperative with a number of other states and countries. The program was initiated in 1945 by J.R. Shay, the of Purdue University, and L.F. Hough, then of the University of Illinois. As the name implies, 'Prima' is the first cultivar to be released under this cooperative effort. The prefix PRI in the name is an acrostic formed from the three institutions involved, viw., Purdue, Rutgers, Illinois. The apple was formerly designated as Co-op 2 and by its breeding number 1225-100 (3). The selection at present is widely planted unnder the Apple Breeders Cooperative program.
