  • Red delicious apple tree--Jenred cultivar
    Patent number: PP5472
    Abstract: A new and distinct spur-type Red Delicious apple variety is provided which originated as a limb mutation of the apple tree of U.S. Plant Pat. No. 2,816. The fruit of the new variety is conic shaped and highly attractive since at maturity it is fully covered with conspicuous dark red stripes over a bright red ground color. Unlike fruit formed on the parent, the fruit of the new variety colors approximately 15 days earlier, and colors more fully in years when environmental conditions do not favour the coloring of Red Delicious apples.
