Priscilla

Co-op 4

(PRI 1659-1 = 'Starking 'Delicious' x PRI 610-2) Introduced as 'Priscilla' (Williams et al. 1972) U.S. Plant Patent No. 3,488

Brief Description

  • Fruit: 64 to 76 mm (2-1/2 to 3 in.); oblate conic to short conic with pointed calyx; green yellow to pale yellow or cream ground color; very bright finish, slightly striped, splashed, 70 to 95% medium red; medium grained, pale yellow colored, unusually crisp and breaking flesh at harvest; moderately aromatic, licorice aroma, mildly acid to sweet, and rich in flavor; moderately juicy; very good dessert quality. Moderate fruit size. Annual cropping. Fruit hangs on the tree until over-ripe. Retains quality for two to three months or more in refrigerated storage if properly handled.
  • Season of Maturity: Two weeks before 'Delicious'.
  • Tree: Moderate vigor; standard bearing habit, somewhat thin branched; medium size.
  • Disease Resistance: Field immune to apple scab; high level of resistance to fire blight; high level of resistance to cedar-apple rust; good level of resistance to powdery mildew.
  • Problems: Small fruit size if not properly thinned; over-cropping; does not color well inside canopy; licorice aroma; longevity in storage variable, inadequate in some years, short shelf life out of storage; tendency for calyx end cracking when over-mature; varietal mix-up caused major nursery to supply an inferior scab resistant cultivar as 'Priscilla' for six years during the early 1980s. Although scab resistant, the bogus 'Priscilla' significantly damaged the cultivar's image.
  • General Recommendation: Suggested for small scale commercial plantings and for specialty markets where the unique flavor can be used as an advantage and fruit is not stored for extended periods.
