The varieties of wheat created through these methods are in the hundreds (going as far back as 1960), more of them being created in higher populated countries such as China. [150] Bread wheat with high grain iron and zinc content has been developed through gamma radiation breeding, [ 152 ] and through conventional selection breeding. [ 153 ]
These variety names are now largely abandoned, but are still sometimes used for distinctive types of wheat such as miracle wheat, a form of T. turgidum with branched ears, known as T. t. L. var. mirabile Körn. The term "cultivar" (abbreviated as cv.) is often confused with "species" or "domesticate". In fact, it has a precise meaning in botany ...
The Watkins Landrace Wheat Collection is a unique resource due to the historical nature of being collected in the 1930’s before widespread globalisation of trade, and before intensive selective breeding in wheat to develop high-yielding elite varieties, which resulted in a significant loss of genetic diversity, including resilience traits.
A cultivar must meet certain criteria in order to be recognised by UPOV as a named variety. In a few lists, variety means something else: a taxonomic rank below that of species (a kind of subspecies). If the species' binomial name is followed by the word var. and another name, that is a botanical variety, not a cultivar.
Ears of compact wheat. Modern wheat varieties have been selected for short stems, the result of RHt dwarfing genes [14] that reduce the plant's sensitivity to gibberellic acid, a plant hormone that lengthens cells. RHt genes were introduced to modern wheat varieties in the 1960s by Norman Borlaug from Norin 10 cultivars of wheat grown in Japan ...
A friend of his sent him seed from Glasgow in 1842. It is a good yielding wheat, high in quality; an excellent milling wheat. It was grown in Canada from 1860 to 1900, and was the industry standard. Ladoga, 1888. A variety originally from Russia. Early maturing, and the parent of Preston and Stanley. Hard Red Calcutta, 1890. A variety from ...
Triticum compactum or club wheat is a species of wheat adapted to low-humidity growing conditions. T. compactum is similar enough to common wheat (T. aestivum) that it is often considered a subspecies, T. aestivum compactum. It can be distinguished by its more compact ear due to shorter rachis segments, giving it its common name.
