(PRI 2058-2 = NJ. 125355 x 'Prima') (Williams et al. 1984)

Brief Description

  • Fruit: 64 to 70 mm (2-1/2 to 2-3/4 in.); variable, oblate-round or short-conic and slightly lobed, wide calyx cavity with open calyx; green-yellow to pale yellow ground color, bright glossy finish; washed 75 to 95% medium to dark, red to purple-red, very attractive; fine grained, pale yellow to cream colored, firm, very crisp and breaking flesh; mildly sub-acid, slightly spicy, slightly aromatic, moderately rich flavor at peak; juicy. Fruit hangs on the tree until over-ripe. Annual, moderate cropping.
  • Season of Maturity: One-half to one week before ĪDeliciousā.
  • Tree: Moderate vigor, slightly upright, spreading to rangy growth habit with limber branches; semi-spur type bearing habit with some bare wood at branch base.
  • Disease Resistance: Field immune to apple scab; highly resistant to powdery mildew; susceptible to cedar-apple rust; moderately resistant to fire blight.
  • Problems: Insufficient storage for season; although flesh texture is maintained for many months, after one and one-half to two months in refrigerated storage, flavor breaks down to undesirable aldehyde and becomes unpalatable; with a large crop, fruit tend to be small and flavor tends to be bland and insufficient; flavor peaks only after two to four weeks in refrigerated storage.
  • General Recommendation: Problems too severe for further consideration. Discarded at Lafayette.
