The Haralson is a cultivar of apple that is medium-sized and has a round-conic shape.
Apple scab is a common disease of plants in the rose family (Rosaceae) that is caused by the ascomycete fungus Venturia inaequalis. While this disease affects several plant genera, including Sorbus, Cotoneaster, and Pyrus, it is most commonly associated with the infection of Malus trees, including species of flowering crabapple, as well as cultivated apple. The first symptoms of this disease are found in the foliage, blossoms, and developing fruits of affected trees, which develop dark, irregularly-shaped lesions upon infection. Although apple scab rarely kills its host, infection typically leads to fruit deformation and premature leaf and fruit drop, which enhance the susceptibility of the host plant to abiotic stress and secondary infection. The reduction of fruit quality and yield may result in crop losses of up to 70%, posing a significant threat to the profitability of apple producers. To reduce scab-related yield losses, growers often combine preventive practices, including sanitation and resistance breeding, with reactive measures, such as targeted fungicide or biocontrol treatments, to prevent the incidence and spread of apple scab in their crops.
The Braeburn is a cultivar of apple that is firm to the touch with a red/orange vertical streaky appearance on a yellow/green background. Its color intensity varies with different growing conditions.
Jonagold is a cultivar of apple that is a cross between the crisp Golden Delicious and the blush-crimson Jonathan; the name Jonagold is a portmanteau of these two variety names. It was developed in 1943 in New York State Agricultural Experiment Station of Cornell University's College of Agriculture and Life Sciences, selected as N.Y. 43013-1 in 1953, officially released in 1968 by Roger Way.
Honeycrisp is an apple cultivar developed at the Minnesota Agricultural Experiment Station's Horticultural Research Center at the University of Minnesota, Twin Cities. Designated in 1974 with the MN 1711 test designation, patented in 1988, and released in 1991, the Honeycrisp, once slated to be discarded, has rapidly become a prized commercial commodity, as its sweetness, firmness, and tartness make it an ideal apple for eating raw. "...The apple wasn't bred to grow, store or ship well. It was bred for taste: crisp, with balanced sweetness and acidity." It has larger cells than most apple cultivars, a trait which is correlated with juiciness, as theoretically a higher number of cells rupture when bitten, releasing more juice in the mouth. The Honeycrisp also retains its pigment well and has a relatively long shelf life when stored in cool, dry conditions. Pepin Heights Orchards delivered the first Honeycrisp apples to grocery stores in 1997. The name Honeycrisp was trademarked by the University of Minnesota, but university officials were unsure of its protection status in 2007. It is now the official state fruit of Minnesota. A large-sized honeycrisp will contain about 113 calories.
Northern Spy also called 'Spy' and 'King', is a cultivar of domesticated apple that originated on the farm of Oliver Chapin in East Bloomfield, New York, in about 1840. It is popular in upstate New York.
An apple is a round, edible fruit produced by an apple tree. Apple trees are cultivated worldwide and are the most widely grown species in the genus Malus. The tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found. Apples have been grown for thousands of years in Asia and Europe and were introduced to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition.
The Golden Orange apple is an apple cultivar that was first developed in Italy in the 1970s by crossing PRI 1956-6 and Ed Gould Golden apples.
The 'Summerfree' is an apple cultivar first developed in Italy in the 1990s by crossing 'PRI 1956-6' and 'Ed Gould Golden' apples. Resistant to apple scab, it has a spreading habit with moderate vigor, the fruit are large with an average weight of 175 g, the skin is smooth, it ripens one to two months before 'Gala', and it has good storage ability.
Applecrabs are various hybrids between crabapples and apples. They are bred for varying reasons, including disease resistance and use in cold climates because they are often hardier than apple trees and their fruit has the good eating qualities of apples.
Rajka is a hybrid cultivar of domesticated apple from the Czech Republic, specifically for eating. Rajka was crossed and developed by the Institute of Experimental Botany from the Champion and Katka apples for scab resistance, hence possible to grow organic.
Pristine apple is a hybrid cultivar of 'Co Op 10' x 'Camuzat' domesticated apples, which are descendants of the 'McIntosh' apple and the 'Starking Delicious'. This cultivar was developed and patented in the United States by the PRI disease resistant apple breeding program, in Indiana, United States in 1994, for its resistance to apple scab. It is susceptible to cedar-apple rust.
The PRI disease resistant apple breeding program is a joint project of the Purdue University, Rutgers University, and the University of Illinois, to breed apple cultivars to be resistant to apple scab. The initialism stands for the three involved universities: Purdue, Rutgers and Illinois.
'Ariane' is a modern cultivar of domesticated apple that was recently developed in France for scab resistance.
'Birgit Bonnier' is a modern cultivar of domesticated apple which have some resistance to apple scab and mildew.
Court Pendu Plat is an extremely old French cultivar of domesticated apple that was first recorded in 1613. The cultivar definitely dates back to earlier than the 17th century, and was probably cultivated by the Romans. It is known for its intense flavor which mellows with storage.
Red Astrachan is a Russian or Swedish cultivar of domesticated apple, which is an early season apple, juicy, tart and mealy texture with pleasant flavour, and use for eating, cooking and cider. It is medium-sized, crimson colored. As all the early season apples, it is not good for storage. It is known by several other names including 'Abe Lincoln', 'American Red', and 'Waterloo'.
The 'Prima' apple is one of the modern disease resistant cultivars of domesticated apple which was bred by the PRI disease resistant apple breeding program in 1958. The disease resistance against apple scab has since been broken.
'Honeygold' is a cold-hardy cultivar of domesticated apple, which was developed to suit for the northern cold areas. It was developed by the Minnesota Agricultural Experiment Station's Horticultural Research Center of the University of Minnesota. They were crossing a Golden Delicious with a Haralson in order to obtain a Golden Delicious style fruit with the cold hardiness of the Haralson, a goal which was successfully achieved.
The MN55 cultivar apple developed by David Bedford, a senior researcher and research pomologist at the University of Minnesota's apple-breeding program, and James Luby, PhD, professor, Department of Horticultural Sciences, Horticultural Research Center, is a cross between Honeycrisp and MonArk (AA44), a non-patented apple variety grown in Arkansas.
