Co-op 32

(PRI 2946-1 = Co-op 10 x Camuzat) (Crosby et al. 1993) Introduced as 'Co-op 32' = PristineTM In 1994. U.S. Plant Patent No. 9,881.

Brief Description

  • Fruit: Variable size 60 x 73 mm (2-3/8 to 2-7/8 in.); oblate-round to round; skin pale green-yellow to cream colored at harvest, maturing to deep yellow, with moderate orange blush on sun-exposed surface. Smooth, glossy, non-russeted finish with inconspicuous lenticels, very attractive. Thin s1dn develops greasy cuticle after 6 to 8 weeks in refrigerated storage. Flesh is pale yellow, crisp and slightly breaking yet melting, medium to fine grained. Mildly acid to sweet, slightly spicy, moderately rich, full flavored. Retains excellent quality and texture at least 4 to 6 weeks in refrigerated storage but remains edible for at least 12 weeks, quite remarkable for an apple of this season. Shows some scald and bruising in storage.
  • Bloom Period: Mid to late mid-season.
  • Season of Maturity: July 20 to August 3 at Lafayette, Indiana.
  • Tree: Moderate vigor, round-top, spreading, good crotch angles, little blindwood, semi-spur type bearing habit with limber wood that has tendency to droop under a heavy crop load. Moderate cropping, some biennial tendency.
  • Disease Resistance: Field immune to scab, resistant to powdery mildew, slightly resistant to cedar-apple rust, moderately resistant to fire blight.
  • Problems: Size can be a problem if crop is too heavy; droopy fruiting branches; bruising and scald show up in storage.
  • General Recommendation: Excellent quality and appearance for its season, significantly better than 'Lodi' or 'Yellow Transparent' suggest a strong niche market for this early apple.
