Genetic evidence strongly suggests that tetraploid wheats originated from a natural cross of a variety of the species T. boeoticum, which contributed the A genome, and a member of the emmer group of wheat, which contributed the B genome. Although the species' origin of the B genome has not been established definitely, there is evidence that Aegilops (Ae.) speltoides was its source. Durum, Persian and Polish wheats are present-day examples of tetraploid wheats. 1, record 1, English, - tetraploid%20wheat

Les indications génétiques recueillies laissent fortement croire que les blés tétraploïdes ont eu pour origine le croisement naturel d'une variété de l'espèce T. boeoticum, qui a apporté le génome A, et un membre du groupe emmer, qui a apporté le génome B. Bien que l'origine de l'espèce du génome B n'ait pas été établie clairement, on peut croire qu'il s'agit des speltoïdes Aegilops (Ae.). Les blés durs persans et polonias sont des exemples actuels de blés tétraploïdes. 1, record 1, French, - bl%C3%A9%20t%C3%A9traplo%C3%AFde

El trigo es un complejo poliploide, cuya importancia y uso a lo largo de la historia ha ido cambiando considerablemente. Las teorías más aceptadas actualmente en cuanto a su origen y evolución, sugieren que todas las especies de Triticíneas proceden de una especie ancestral de siete pares de cromosomas, que ha dado lugar a tres grupos según su nivel ploidico: trigo diploide, tetraploide y hexaploide... En lo referente al trigo tetraploide, la especie silvestre es T.turgidum ssp. dicoccoides L. La domesticación de este trigo tetraploide silvestre dio lugar a T. turgidum ssp. dicoccum, del que evolucionaron posteriormente otras subespecies de trigos duros, T. turgidum ssp. durum MacKey, T. turgidum ssp. turgidum L. y T. turgidum ssp. carthlicum A. et D. Löve. Otra especie tetraploide es T. timophevii Zhuk que incluye tanto a formas silvestres (T. timophevii ssp. araraticum) como cultivadas (T. timophevii ssp.timophevii). 2, record 1, Spanish, - trigo%20tetraploide
