Abstract

A new and distinct cultivar of apple tree is distinctly characterized by its high fruit quality, the attractive red color and good flavor of the fruit, and its resistance to Venturia inaequalis (Cke.) Wint., the causal agent of apple scab disease. This new cultivar of apple tree, now designated as COOP 21, is a seedling of known parentage planted in 1969 in the PA block of the apple breeding orchard at the Pomology Research Center at the Illinois Agricultural Experimental Station, Urbana, Ill., which site is a cultivated area. In the above-mentioned orchard, its position was Row 1, Tree 58, having the designation PRI 2259-100 in the breeding records. After observation, the selection was asexually reproduced by grafting on both seedlings and dwarfing roots. The grafted material has maintained the described characteristics after propagation.

Description

DESCRIPTION OF THE DRAWINGS
FIG. 1 is a photograph showing typical examples of fruit and foliage of COOP 21.
BACKGROUND OF THE INVENTION
The present new cultivar is a seedling produced from crossing the seedling N.J. 123249 as the seed parent and the seedling PRI 1235-100 as the pollen parent in 1966 at New Brunswick, N.J. This new cultivar carries a genetic factor, Vf, inherited from Malus floribunda 821, which causes it to be resistant to infection caused by Venturia inaequalis. The presence of this factor has been proven repeatedly by controlled inoculation tests in the Purdue University greenhouse of the seedling and its offspring produced from controlled crosses. A complete pedigree is shown below: ##STR1##
F2 26829-2-2 has the following parentage: ##STR2##
The new cultivar produces a moderately upright and vigorous tree similar to `Delicious`. It is field immune to apple scab and is only slightly susceptible to fireblight and powdery mildew.
The apple fruit has fine dessert and culinary quality quite similar to `Prima`, but is less acidic. Additionally, a higher proportion of the fruit surface has a bright red color. The characteristic texture and flavor are maintained up to four weeks at 34° F. The skin of the fruit is smooth and very glossy, having light tan dots spaced widely, but being more numerous near the apex. The skin is moderately tough.
