William's Pride

Co-op 23

(PRI 2845-1 = PRI 1018-101 x NJ. 50) Introduced as 'Williams' Pride' (Janick et al. 1988) U.S. Plant Patent No. 6,268

Brief Description

  • Fruit: 67 to 76 mm. or more (2-1/2 to 3+ in.); variable size; round to conic, variable shape; lime green to pale yellow ground color, washed and faintly striped, bright, 70 to 99% medium to dark red or purple-red, conspicuous, slightly sunken lenticels; medium to coarse grained, cream colored, firm, very crisp and breaking flesh; moderately to mildly sub-acid, slightly spicy, full rich flavor, juicy; excellent summer dessert quality. Moderate to large fruit size. Fall quality in the middle of the summer. Annual cropping, with slight biennial tendencies. Retains quality and crisp flesh texture for 6 weeks or more in refrigerated storage.
  • Season of Maturity: Seven to eight weeks before 'Delicious'.
  • Tree: Vigorous, spreading, 90" crotch angles, very spurry wood. Similar in growth habit to 'Empire', but not quite as spurry. Moderately large tree size.
  • Disease Resistance: Field immune to apple scab; field immune to cedar-apple rust; high level of resistance to fire blight; good level of resistance to powdery mildew.
  • Problems: Severe watercore may be a significant problem in some seasons. Slight bitter pit observed in a few seasons. Severe bitter pit was observed on young trees with their first crop on MM-111 rootstock, on very sandy soil, under heavy nitrogen and irrigation. Fruit borne in clusters on short spurs, may tend to be pushed off as they swell, giving some loss to dropped fruit. Slightly coarse flesh texture. Uneven ripening will require two or more pickings.
  • General Recommendation: Suggested for advanced commercial testing on soils where nutrient deficiencies do not predispose trees to bitter-pit, as well as small scale and home grower plantings. Produced large, high quality fruit, ripening with the earliest red apple cultivars and relatively long storage-life for early entry and extended use in the summer apple market. Not recommended on MM-111 rootstock, on bitter-pit prone soils, or under high nitrogen fertilization.
