(PRI 2712-4 = PCF 2-134 x PRI 669-205 (669NJ5)) Patent applied for.
- Fruit: 76 mm or more (3+ in.); round to short-conic; green-yellow to yellow ground color; moderate to bright finish; slightly splashed, washed 75 to 90% light to medium red to orange; moderate grained, pale yellow to cream colored, extremely firm, very crisp and breaking flesh; sweet to mildly sub-acid, slightly spicy, fruity, rich, pleasant flavor, juicy. Open calyx tube. Somewhat bland at harvest, flavor improves greatly after one to two months in storage. Retains quality in refrigerated storage for seven months or more. Co-op 25 is one of the longest storing selections to originate from the PRI program. Fruit hangs on the tree very well. Observed to be susceptible to apple maggot in late-season unsprayed blocks.
- Season of Maturity: One to one-half week before 'Delicious'.
- Tree: Moderate vigor, spreading with 90 degree crotch angles, somewhat thin, slightly weeping branches with moderately bare-wooded bases; fruit tend to be borne on long spurs, with some slight tendency for tip-bearing, and some tendency for fruit to be borne in clusters; slight biennial tendency.
- Disease Resistance: Field immune to apple scab; moderately resistant to powdery mildew; highly resistant to cedar-apple rust; highly susceptible to fire blight.
- Problems: Mediocre growth habit (partially overcome by ability of fruit to hang very well); tendency for reduced fruit size and reduction in flavor with a heavy crop; high fire blight susceptibility. Low level of moldy-core observed under the absence of fungicidal sprays.
- General Recommendation: Suggested for advanced testing in Oregon, Washington, U.S.; British Columbia, Canada, and other areas where fire blight is not a major concern.
- Availability: trees will be available from licensed nurseries under the name Scarlett O'HaraTM, which is a trademark of the Purdue Research Foundation
