Triticum timopheevii

Triticum timopheevii (Zhuk.) Zhuk. - Timopheev's wheat - TRTI - Tracey Slotta %40 USDA-NRCS PLANTS Database

Triticum timopheevii is a species of wheat in the genus Triticum. It is commonly known as Timopheev's wheat and is primarily grown in the Caucasus region. This species is notable for its resistance to certain diseases and its adaptability to various climatic conditions.

Taxonomy and Nomenclature

Triticum timopheevii was first described by the Russian botanist Nikolai Vavilov in the early 20th century. The species is named in honor of the Russian agronomist Pavel Timofeev, who made significant contributions to the study of wheat.

Morphology

Triticum timopheevii is a tetraploid wheat species, meaning it has four sets of chromosomes. The plant has a robust culm and broad leaves. The spikelets are compact, and the grains are typically larger than those of common wheat (Triticum aestivum).

Distribution and Habitat

This species is predominantly found in the Caucasus region, including parts of Georgia, Armenia, and Azerbaijan. It thrives in mountainous and semi-arid environments, where it is cultivated for both food and forage.

Agronomic Importance

Triticum timopheevii is valued for its disease resistance, particularly against rusts and smuts. It is also known for its drought tolerance, making it a vital crop in regions with limited water resources. The species is often used in breeding programs to transfer these beneficial traits to other wheat varieties.

Uses

The grains of Triticum timopheevii are used to make bread, porridge, and other traditional dishes in the Caucasus region. The straw is also used as fodder for livestock.

Conservation

Due to its limited distribution and the increasing preference for high-yielding wheat varieties, Triticum timopheevii is considered a genetic resource that needs conservation. Efforts are being made to preserve its germplasm in seed banks and through in situ conservation in its native habitat.
