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.
