Triticum araraticum 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. 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. The relationship has led some taxonomists to classify "T. araraticum" as a subspecies of "T. timopheevii". In July 1988 different lines of "T. araraticum" were studied using the C-banding method revealing
Crop weed Crop weed Crop weeds are weeds that grow amongst crops. Examples of crop weeds include chickweed, barnyard grass, dandelion, striga and fallopia japonica. Despite the potential for some crop weeds to be used as a food source, many can also prove harmful to crops, both directly and indirectly. Crop weeds can inhibit the growth of crops, contaminate harvested crops and often spread rapidly. They can also host crop pests such as aphids, fungal rots and viruses. Cost increases and yield losses occur as a result. Striga, one of the main cereal crop weeds in Sub-Saharan Africa, commonly causes yield losses
