Co-op 34

(PRI 1571-2 = PRI 612-1 x Monroe) (Crosby et al. 1993).

Fruit: 64 to 73 mm (2-1/2 to 2-7/8 in.); round or short-conic to conic; oblong on young trees Skin is washed, 60 to 80% light to medium red over a pale green-yellow ground color at harvest. Ground color matures to pale or light yellow; slightly tough, moderately thick skin. Flesh is white to cream, slightly crisp, firm, medium grained. Sprightly to moderately acid at harvest, reduced to moderately acid in storage; slightly spicy, moderately full-flavored (similar to 'Jonathan), moderately juicy. Retains texture and quality for three months in refrigerated storage.

Tree: Standard, round-top, spreading growth habit, moderately sturdy branches, with 90 degree crotch angles; similar to 'Jonathan'. Exhibits a high degree of branching and smaller diameter wood than desirable, but not excessive. A small amount of bare wood tends to develop at the base of branches. Annually moderate to heavy producer, with little biennial tendency.

Disease Resistance: Field immune to scab, moderately resistant to powdery mildew, highly resistant to cedar-apple rust, highly resistant to fire blight.

General Recommendation: Good annual cropping of attractive, mostly conic-shaped fruit with similar quality and flavor to 'Jonathan' with very good overall disease resistance. Appears to be adapted to the U.S. Midwest and other 'Jonathan' growing areas.
