This invention relates to a new cultivar of apple tree which is characterized by resistance to apple scab and cedar apple rust, outstanding fresh fruit quality, smooth, slightly waxy skin, and a maturity approximately 7.5 to 8 weeks before `Delicious` and 4 to 4.5 weeks before `Prima.`

Apple tree `COOP 23`

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.

Apple tree

An apple tree having immunity to scab and attractive fruit of high quality as a late summer dessert apple.

A new and distinct cultivar of apple tree which is distinctly characterized by its high fruit quality and its resistance to Venturia inaequalis (Cke.) Wint., the causal agent of the apple scab disease. This new variety of apple tree, now designated as COOP 22, is a seedling of known parentage planted in 1965 in the PW Breeding Orchard of the Department of Horticulture at the Illinois Agricultural Experiment Station, Urbana, Ill., which site is a cultivated area. In the above mentioned orchard, its position was Row 40, Tree 116, having the designation PRI 2016-100 in the breeding records. After observation the selection was asexually reproduced by grafting on seedling apple roots. The grafted material has maintained the described characteristics after propagation.

COOP 22

A new and distinct cultivar of apple tree which is distinctly characterized by its high fruit quality, its resistance to infection caused by Venturia inaequalis (Cke.) Wint., the casual agent for the apple scab disease, due to the fact that this new cultivar carries the genetic factor V.sub.f, and closely resembles `Golden Delicious` but differs from `Golden Delicious` in that it is resistant to apple scab, has freedom from stem cavity russet, bears a waxier skin, and green-tinged lenticels at harvest. This new variety of apple tree, now designated as COOP 16, was discovered by applicants in September, 1973, at Lafayette, Ind., in a cultivated area. The tree is a seedling of known parentage planted in 1966 in Block C of the Hinsley Breeding Orchard at the Horticultural Farm of the Purdue University Agricultural Experiment Station, West Lafayette, Ind. In the above orchard, its position was Row 21, Tree 79, having the description PRI 2174-3 in the breeding records. After observation, the selection was asexually propagated by grafting on seedling apple roots. The grafted material has maintained the described characteristics after propagation.

Distinct cultivar of apple tree: COOP 16

This invention relates to a new cultivar of apple tree which is scab resistant, and which matures about eight weeks before Delicious and four and one-half weeks before Prima.

Apple tree (Coop 12)

This invention relates to an apple tree cultivar, said apple tree being scab resistant and having a fruit maturity about 1 week after Delicious and 41/2 weeks after Prima.

Apple tree (Coop 10)

This invention relates to a new cultivar of an apple tree which is scab resistant, and is characterized by a maturity 7 weeks before Delicious and 31/2 weeks before Prima.

Apple tree (Coop 13)

This invention relates to a new cultivar of apple tree which is scab resistant, and characterized by a maturity about 6 weeks before Delicious and about 21/2 weeks before Prima.

Apple tree (Coop 14)

1. A new and distinct apple tree substantially as shown and described particularly characterized by resistance to apple scab, smooth skin, excellent fresh fruit quality characterized by the ability to maintain quality without shrivelling in storage, and outstanding processing ability, said fruit maturing substantially at the same time as 'Golden Delicious'.
