Definitions

  • the present new cultivar which is named Priscilla, is a seedling produced from crossing Starking Delicious as the seed parent and the seedling 6102 as the pollen parent in 1961 in Door County, Wis.
  • This new cultivar carries a genetic factor, V,, inherited from Malus floribunda 821 which causes it to be resistant to infection caused by Ventzm'a inaequalis. The presence of this genetic factor has been repeatedly proven by controlled inoculation tests in the Purdue greenhouse of the seedling and of its offspring produced from controlled crosses. The complete pedigree is shown below:
  • Starking Delicious (1659-2) Priscilla[ Golden McIntosh Delicious 943-28 M alus floribunda 821
  • the new cultivar produces a moderately spreading and vigorous tree. The tree is productive and produces annually. It is resistant to scab and shows field resistance to fire blight and powdery mildew.
  • the tree flowers with or just after McIntosh and along with Prima which is described in US. Plant Pat. No. P.P. 3,134.
  • the apple fruit has fine dessert quality, with crisp texture and pleasant flavor.
  • the characteristic flavor is maintained 2-3 months or more at 34 F. There is little tendency of the fruit to drop before maturity.
  • Corolla 4 cm. (1 /2 in.) diameter at anthesis.
  • Color Solferino purple, ranging from plate 26 (tight bud) to 26/2 to paler in open flower. Outside of petal pigmented in patches at anthesis.
  • Cavity Acute, deep, medium width, smooth.
  • Basin Shallow and narrow.
  • Calyx Persistent, curved to upright, closed.
  • Calyx tube Urn-shaped.
  • Carpels Elongated, mucronate, smooth.
  • Seed Acute, not tufted.
  • Tree Moderately spreading and vigorous. Frequently terminal growth is determinate ending in a flower bud, occasionally the following years growth is bifurcated.
  • our new cultivar apple is distinguished by its resistance to scab and its excellent dessert quality.
  • a new and distinct apple tree substantially as shown and described particularly characterized by resistance to apple scab, excellent fresh fruit quality as regards flavor and crisp texture and maturing approximately two (2) weeks before Delicious, one (1) week before Jonathan, or one and one-half (1 /2) weeks after Prima.
