Co-op 37

(PRI 2750-7 = Co-op 17 (PRI 1689-100) x Golden Delicious) (Crosby et al. 1993)

Brief Description

  • Fruit: 67-76 mm (2-5/8 x 3 in.); short conic to conic; skin is green-yellow at harvest, with a slight orange blush on the sun-exposed cheek; maturing to yellow. Smooth, glossy finish with little russet and inconspicuous lenticels; moderately thick and tender. Flesh is pale yellow to cream colored, firm, very crisp and breaking yet melting, juicy, medium to fine grained. Moderately acid, rich, slightly aromatic, full flavored, and juicy. Retains quality and texture 4 to 5 months in refrigerated storage.
  • Bloom Period: Late mid-season.
  • Season of Maturity: October 10 to 20 at Lafayette, Indiana.
  • Tree: Moderately vigorous, standard, round top; semi-spur bearing habit. Moderate bearing with some biennial tendencies.
  • Disease Resistance: Field immune to scab, highly resistant to powdery mildew, susceptible to cedar-apple rust; resistant to fire blight.
  • Problems: Fruit size smaller than 'Golden Delicious'. Tough skin, large core.
  • General Recommendation: A 'Golden Delicious' seedling maturing a week later with a full, rich flavor, crisp and breaking yet melting flesh type, and a good overall level of disease resistance. Storage life superior to 'Golden Delicious' but quality not on a par with 'GoldRush' (Co-op 38).
