Topaz (apple)
Topaz is a cultivar of dessert apple that was developed in Czech Republic by the Institute of Experimental Botany for scab resistance. According to Orange Pippin it is "one of the best modern disease-resistant varieties, with fairly sharp flavour". See also *Applecrab Applecrabs are various hybrids between crabapples and apples.

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 var ...

Apple
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 mo ...

Czech Republic
The Czech Republic, or simply Czechia, is a landlocked country in Central Europe. Historically known as Bohemia, it is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the southeast. The Czech Republic has a hilly landscape that covers an area of with a mostly temperate continental and oceanic climate. The capital and largest city is Prague; other major cities and urban areas include Brno, Ostrava, Plzeň and Liberec. The Duchy of Bohemia was founded in the late 9th century under Great Moravia. It was formally recognized as an Imperial State of the Holy Roman Empire in 1002 and became a kingdom in 1198. Following the Battle of Mohács in 1526, the whole Crown of Bohemia was gradually integrated into the Habsburg monarchy. The Protestant Bohemian Revolt led to the Thirty Years' War. After the Battle of White Mountain, the Habsburgs consolidated their rule. With the dissolution of the Holy Empire in 1806, the Cro ...

Institute Of Experimental Botany
An institute is an organisational body created for a certain purpose. They are often research organisations (research institutes) created to do research on specific topics, or can also be a professional body. In some countries, institutes can be part of a university or other institutions of higher education, either as a group of departments or an autonomous educational institution without a traditional university status such as a "university institute" (see Institute of Technology). In some countries, such as South Korea and India, private schools are sometimes referred to as institutes, and in Spain, secondary schools are referred to as institutes. Historically, in some countries institutes were educational units imparting vocational training and often incorporating libraries, also known as mechanics' institutes. The word "institute" comes from a Latin word ''institutum'' meaning "facility" or "habit"; from ''instituere'' meaning "build", "create", "raise" or "educate". ...

Apple Scab
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.Jha, G., Thakur, K., & Thakur, P. (2009). The ''Venturia'' Apple Pathosystem: Pathogenicity Mechanisms and Plant Defense Responses. ''Journal of Biomedicine and Biotechnology'', 2009. doi:10.1155/2009/680160 The reduction of ...

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 ...

Opal (apple)
opal® is the brand name for apple cultivar 'UEB 32642'. The variety originates from a natural crossing of ' Golden Delicious' with 'Topaz'. Developed by the Institute of Experimental Botany in Prague, it is grown by FirstFruits Farms LLC in Washington and marketed by FirstFruits Marketing. It is also cultivated in Austria, Italy, Spain, Germany, Slovenja, France and the United Kingdom.

Rajka (apple)
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. Description Tree is moderately vigorous, standard type, produces spurs freely, precocious in cropping, highly productive, fruits do not fall prematurely, good pollinator with mid-season blossoming, resistant to scab and tolerant to powdery mildew. Fruits are medium to large, globose conical, medium stem length. Yellow under-color is covered on almost the entire skin surface with an attractive bright red over-color. There is some russeting in stem cavity which occasionally may extend out over base. Flesh yellowish, juicy with medium grained texture and distinctive pleasant aroma. Overall it is an early-winter, disease resistant, dessert variety with outstanding color, good rather sweet flavor and medium storage life. May be ...
