Prima Apple
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. Like other "PRI" apples it is of complex ancestry to ensure the utmost disease resistance and various cultivation advantages, along with a fresh vibrant flavor. Its ancestry includes the ' Rome Beauty', 'Melba', 'Golden Delicious' and 'Wealthy' apples, as well as the ''Malus floribunda'' crabapple for scab resistance. "PRI" is impressed in the cultivars name "PRI"ma. 'Prima' was originally very resistant to apple scab due to having the Vf gene. However scab has since evolved around that resistance, and 'Prima' apples are now heavily affected by apple scab in regions where the new apple scab has spread to. As such, 'Prima' is no longer a recommended apple variety for garden use without pesticides. It has a juicy flesh with a balanced mild sub-acid fla ...

Malus
''Malus'' ( or ) is a genus of about 30–55 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple, crab apples, wild apples, and rainberries. The genus is native to the temperate zone of the Northern Hemisphere. Description Apple trees are typically talI at maturity, with a dense, twiggy crown. The leaves are long, alternate, simple, with a serrated margin. The flowers are borne in corymbs, and have five petals, which may be white, pink, or red, and are perfect, with usually red stamens that produce copious pollen, and a half-inferior ovary; flowering occurs in the spring after 50–80 growing degree days (varying greatly according to subspecies and cultivar). Many apples require cross-pollination between individuals by insects (typically bees, which freely visit the flowers for both nectar and pollen); these are called self-sterile, so self-pollination is impossible, making pollinating insects essential.

Malus Domestica
An apple is an edible fruit produced by an apple tree (''Malus domestica''). 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 today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting. There are more ...

PRI Disease Resistant Apple Breeding Program
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. Formation During the early 20th century, C. S. Crandall carried out intensive studies of crosses between the cultivated apples and crab apples, with the goal of scab resistance. However, Crandall didn't see any fruits of his investigations. L. Fredric Hough, then a graduate student at the University of Illinois, studied Crandall's work. Hough published a paper in 1944, leading to a 1945 collaboration with Purdue University Pathology, pathologist J. Ralph Shay. Hough then relocated to Rutgers and the collaborative effort was extended there. The program The modified backcross breeding strategy used cultivated apple with recurrent parents from selected susceptible members of the wild ancestral genus ...

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Rome Beauty
The Rome apple (also known as Red Rome, Rome Beauty, Gillett's Seedling) is a cooking apple originating near Rome Township, Ohio, in the early 19th century. This apple remains popular for its glossy red color and for its utility in cooking. Characteristics The Rome is rounded, all red, and very glossy, with a thick skin and firm flesh. It is primarily used for baking, as its flavor develops when cooked, and it holds its shape well. It is commonly described as less desirable as an eating apple because of its subtle flavor that is not as sweet, flashy, or tart as some other varieties. It comes to market in late September and is considered a good keeper. Rome apples are widely grown and available, and are a staple variety in American commerce. Origins The story is given that in 1817 Joel Gillet (also spelled "Gillett" or "Gillette" by his descendants) found a seedling tree in a shipment from a nursery. His son planted the tree on the banks of the Ohio River in Rome Township near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melba (apple)
Melba is a Canadian cultivar of domesticated apple, which was developed by W. T. Macoun at the Central Experimental Farm, in Ottawa, Ontario by crossing a McIntosh with a Liveland Raspberry apple. It has a yellow skin washed with crimson colour. Flesh is extremely white, firm and crisp. Flavor is sweet with hints of tart. There is also a Red Melba mutation which is more red coloured, and is ripening later in season. This tree is very productive and can bear fruit at a young age, but has a biennial tendency Biennial bearing (or alternate) bearing is a term used in pomology to refer to trees that have an irregular crop load from year to year. In the "on" year too much fruit is set, leading to small fruit size. Excess weight in the main branches can be ... and early harvest. Need high skill gardening but highly rewarded.

Golden Delicious
'Golden Delicious' is a cultivar of apple. It is one of the 15 most popular apple cultivars in the United States. It is not closely related to 'Red Delicious'. History Golden Delicious arose from a chance seedling, possibly a hybrid of 'Grimes Golden' and 'Golden Reinette'. The original tree was found on the Mullins' family farm in Clay County, West Virginia, United States, and was locally known as Mullin's Yellow Seedling and Annit apple. In Clay County, George Deems was instrumental in preserving and perpetuating the original Stark's Golden delicious apple tree on A. H. Mullins property back in 1938. The famed tree came to the attention of the Stark Brothers a number of years before, when Mr. Mullins sent three apples to Mr. Stark one fine April. The Golden Delicious' long keeping qualities were soon abundantly evident to Mr. Stark, as well as to United States Pomologist Colonel Brackett, in Washington, and the nursery bought the tree and ground on which it stands from Mr. ...

Wealthy (apple)
The Wealthy is an American apple cultivar, and was the earliest to thrive in the Minnesota climate. Horticulturalist Peter Gideon first grew it in 1868, after years of trial and error with various apple varieties. History Before 1868, only crab apples grew reliably in Minnesota. Indigenous peoples in the area harvested other crops, but they did not grow apples. Early White settlers to Minnesota tried to grow apples using seeds and seedlings from their former homes to the east and the south, but their plants died, usually because of the region's harsh winters. In 1853, Peter Gideon moved to Minnesota for health reasons and took a homestead with his family on the shores of Lake Minnetonka, near Excelsior. He had learned fruit-growing as a child, and when he arrived on his new land, he planted a bushel of apple seeds he had brought with him from his former home in Illinois. In the years that followed, Gideon experimented with apple and fruit growing, planting thousands of trees, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malus Floribunda
''Malus floribunda'', common name Japanese flowering crabapple, Japanese crab, purple chokeberry, or showy crabapple, originates from Japan and East Asia. It may be a hybrid (biology)#In plants, hybrid of ''M. toringo'' with ''M. baccata'', in which case it would be written as ''Malus'' × ''floribunda''. Description ''Malus floribunda'' forms a round-headed, deciduous tree up to in height, with narrow leaves on arching branches. The flowers, appearing in spring, are white or pale pink, opening from crimson buds. The red or yellow fruit is about 1 cm in diameter, ripening in autumn. Resistance Tree has good disease resistance to apple scab and powdery mildew. The initiators of the PRI disease resistant apple breeding program have discovered that ''Malus floribunda'' has resistance to the apple scab and founded the program to introduce this ''VF gene'' into cultivated apples. Their work had been progressing with great success. Awards This crabapple species is considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Applecrab
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. Applecrabs are sometimes distinguished from apples if the fruit diameter is less than . Cold-hardy applecrabs Director of the Canadian Central Experimental Farm William Saunders (1836–1914) produced a number of such hybrids as part of an effort to develop good-quality eating apples for the Canadian prairies by crossing the domesticated apple cultivars with selected winter-hardy crabapple species. Cultivars include: * Malus 'Columbia', from one of Saunders' early experiments crossing ''M. baccata'' (from Siberia) with relatively hardy apples. * Malus 'Kerr', from crossing 'Dolgo' crabapple and 'Haralson' apple. * Malus 'Osman', from one of Saunders' early experiments crossing ''M. baccata'' with relatively hardy apples. * Mal ...
