A new apple variety distinguished by resistance to apple scab; crisp flesh and excellent dessert quality; attractive color (almost completely red); ripens in the middle of September in West Lafayette, Ind.; size varies from 2.75 to 3 inches in diameter; and good storage ability (can be stored up to six months at 1&#xb0; C.).

Apple tree named 'CO-OP 39'

A new apple variety of distinguished by a small size fruit; resistance to apple scab; fruit having extremely crisp flesh and excellent flavor; and fruit that ripens in mid-September, but does not readily fall from the tree.

Apple tree named 'Co-op 33'

A new apple variety distinguished by good storage ability, good to excellent dessert quality, and a resistance to apple scab, cedar rust, and fireblight, with a moderate resistance to powdery mildew.

Apple tree named 'Co-op 29'

This invention is a new and distinct cultivar of apple tree (Malus Xdomestica Borkh). It was discovered in the course of an attempt to develop improved apple cultivars with high fruit quality and resistance to Venturia inaequalis (Cke.) Wint., the casual agent of the scab disease of apple. The tree is a seedling of known parentage planted in Apr. 15,1975 in the HF Block of an apple breeding orchard on the Hinsley tract of the Purdue Horticulture Research Farm, West Lafayette, Ind., in row 34. Because the trees in this row were spaced very closely its tree number was not recorded. When selected it had the designation PRI 2946-1 in the breeding records and was tested under the designations HFRow 34 and Co-op 32.

Apple tree `Co-op 32`

The cultivar of the present invention, designated `Co-op 38`, is a new and distinct cultivar of apple tree (Malus.times.domestica Borkh.). It was discovered in October of 1980 at West Lafayette, Ind., in the course of an attempt to develop improved apple cultivars with high fruit quality and resistance to Venturia inaequalis (Cke.) Wint., the causal agent of the scab disease of apple. The tree is a seedling of known parentage planted in May of 1973 in the HE Block of the apple breeding orchard on the Hinsley tract of the Purdue Horticulture Research Farm, West Lafayette, Ind. In the above mentioned block, its position was Row 4, Tree 16, having the designation PRI 2750-6 in the breeding records.

Apple tree `Co-op 38`

The cultivar of the present invention, designated `Co-op 30`, is a new and distinct cultivar of apple Tree (Malus.times.domestica Borkh.). It was discovered in October of 1978 at West Lafayette, Ind., in the course of an attempt to develop improved apple cultivars with high fruit quality and resistance to Venturia inaequalis (Cke.) Wint., the causal agent of the scab disease of apple. The tree is a seedling of known parentage planted in May of 1972 in the CL Block of the apple breeding orchard on the old Clark Farm tract of the Purdue Horticulture Research Farm, West Lafayette, Ind. In the above mentioned block, its position was Row 4, Tree 38, having the designation PRI 2693-1 in the breeding records.

Apple tree named Co-Op 30`

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.
