(PRI 2720-18 = PRI 2050-2 x Golden Delicious) (Crosby et al. IM)

Brief Description

  • Fruit: 64 to 73 mm (2-1/2 to 2-7/8 in.); short conic to conic; skin is pale green-yellow at harvest with a slight pink blush on the sun exposed surface, maturing to pale yellow; thin and tender. Flesh is cream colored, crisp and breaking yet melting, medium grained juicy. Moderately to mildly acid, rich, fruity, full flavor. Retains texture and quality for 3 to 4 months in refrigerated storage.
  • Bloom Period: Late midseason.
  • Season of Maturity: October 15 to 20 at Lafayette Indiana.
  • Tree: Very desirable growth habit; moderate vigor, slightly upright, limited branching, sturdy wood, semi-spur type growth habit, fruit tends to be borne in clusters on relatively short spurs inside the canopy of the tree. Moderate to heavy producer with strong biennial fruit bearing tendency. Fruit thinning should be conducted annually.
  • Disease Resistance: Field immune to scab, highly resistant to powdery mildew, moderately resistant to cedar-apple rust, resistant to fire blight.
  • Problems: Fruit size smaller than 'Golden Delicious'; quality not as good as 'GoldRushâ. Checked lenticels detected in Mississippi in 1993.
  • General Recommendation: A Golden Delicious seedling maturing a week later with a unique fruity flavor and a high over-all level of disease resistance. Tendency to overcrop if not thinned. Storage life had been considered superior to 'Golden Delicious'; but quality not on a par with 'GoldRushâ (Co-op 38).
