Wheat Taxonomy
During 10,000 years of cultivation, numerous forms of wheat, many of them hybrids, have developed under a combination of artificial and natural selection. This diversity has led to much confusion in the naming of wheats. Genetic and morphological characteristics of wheat influence its classification; many common and botanical names of wheat are in current use. ''Aegilops'' and ''Triticum'' Similarities and differences The genus ''Triticum'' includes the wild and domesticated species usually thought of as wheat. In the 1950s growing awareness of the genetic similarity of the wild goatgrasses ('' Aegilops'') led botanists such as Bowden to amalgamate ''Aegilops'' and ''Triticum'' as one genus, ''Triticum''. This approach is still followed by some (mainly geneticists), but has not been widely adopted by taxonomists. ''Aegilops'' is morphologically highly distinct from ''Triticum'', with rounded rather than keeled glumes. Hybridisation and polyploidy ''Aegilops'' is impo ...

Triticum Spelta
Spelt (''Triticum spelta''), also known as dinkel wheat is a species of wheat. It is a relict crop, eaten in Central Europe and northern Spain. It is high in protein and may be considered a health food. Spelt was cultivated from the Neolithic period onward. It was a staple food in parts of Europe from the Bronze Age to the Middle Ages. It is used in baking, and is made into bread, pasta, and beer. It is sometimes considered a subspecies of the closely related common wheat (''T. aestivum''), in which case its botanical name is considered to be ''Triticum aestivum'' subsp. ''spelta''. It is a hexaploid, most likely a hybrid of wheat and emmer. Description Spelt is a species of ''Triticum'', a large stout grass similar to bread wheat. Its flowering spike is slenderer than that of bread wheat; when ripe, it bends somewhat from the vertical. The spike is roughly four-edged. The axis of the spike is brittle and divided into segments; it shatters into separate segments when ful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triticum Aestivum
Common wheat (''Triticum aestivum''), also known as bread wheat, is a cultivated wheat species. About 95% of wheat produced worldwide is common wheat; it is the most widely grown of all crops and the cereal with the highest monetary yield. Taxonomy Numerous forms of wheat have evolved under human selection. This diversity has led to confusion in the naming of wheats, with names based on both genetic and morphological characteristics. List of common cultivars * Albimonte * Manital * Shirley * Hilliard Phylogeny Bread wheat is an allohexaploid a combination of six sets of chromosomes from different species. Of the six sets of chromosomes, four come from emmer (''Triticum turgidum'', itself a tetraploid) and two from ''Aegilops tauschii'' (a wild diploid goatgrass). Wild emmer arose from an even earlier ploidy event, a tetraploidy between two diploids, wild einkorn (''T. urartu'') and '' A. speltoides'' (another wild goatgrass).

Hexaploid
Polyploidy is a condition in which the cells of an organism have more than two paired sets of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two complete sets of chromosomes, one from each of two parents; each set contains the same number of chromosomes, and the chromosomes are joined in pairs of homologous chromosomes. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis; the sporophyte generation is diploid and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aegilops Speltoides
''Aegilops speltoides'' ( syn. ''Sitopsis speltoides'' ( Tausch) Á.Löve) is an edible goatgrass in the family Poaceae native to Southeastern Europe and Western Asia, which is often used for animal feed, and it has grown in cultivated beds. This plant is an important natural source of disease resistance in wheat, and it is known or likely to be susceptible to barley mild mosaic bymovirus. Genome ''Aegilops speltoides'' is a diploid of 2''n'' = 2''x'' = 14. ''A. speltoides'' is divided into two morphotypes, the dominant ' and the recessive In genetics, dominance is the phenomenon of one variant (allele) of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and ... '. References Sources Brunt, A.A., Crabtree, K., Dallwitz, M.J., Gibbs, A.J., Watson, L. and Zurcher, E.J. (eds.) (1996 onwards).

Hybridisation (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different variety (botany), varieties, subspecies, species or genus, genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera (genetics), chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show Heterosis, hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductive isolation, reproductively isola ...

Triticum Araraticum
''Triticum araraticum'' (Araratian wild emmer or Armenian wild emmer) is a wild tetraploid species of wheat. ''T. araraticum'' is one of the least studied wheat species in the world.E. D. Badaeva, R. L. Boguslavsky, N. S. Badaev and A. V. Zelenin. 1988. ''Intraspecific chromosomal polymorphism of Triticum araraticum (Poaceae) detected by C-banding technique''. Plant Systematics and Evolution. Vol. 169, No. 1/2 Genealogy The ''T. araraticum'' species appears to have arisen from the natural hybridization of T. boeoticum and Aegilops speltoides. ''T. araraticum'' is similar to the domestic T. timopheevii in several ways including physical appearance, cytoplasm type and DNA content.Jakubizner M. M. 1932. Wheats of Syria, Palestina, and Tranjordan, and their role in breeding and agronomy. WIR publ. p. 157-160 (in Russian) The relationship has led some taxonomists to classify ''T. araraticum'' as a subspecies of ''T. timopheevii''. In July 1988 different lines of ''T. araraticum'' ...

Triticum Dicoccoides
Emmer is a hybrid species of wheat, producing edible seeds that have been used as food since ancient times. The domesticated types are ''Triticum turgidum'' subsp. ''dicoccum'' and ''T. t. ''conv.'' durum''. The wild plant is called ''T. t.'' subsp. ''dicoccoides''. The seeds have an awned covering, the sharp spikes helping the seeds to become buried in the ground. The principal difference between the wild and the domestic forms is that the ripened seed head of the wild plant shatters and scatters the seed onto the ground, while in the domesticated emmer, the seed head remains intact, thus making it easier for people to harvest the grain. Along with einkorn, emmer was one of the first crops domesticated in the Near East. It was widely cultivated in the ancient world, but is now a relict crop in mountainous regions of Europe and Asia. Emmer is one of the three grains called farro in Italy. Etymology Emmer is first attested in 1908 in English as a loanword from German , var ...
