小麦属(Triticum)的分类,最早是Lnne于1764年进行的,以后许多学者曾作过修订和创新。近十五年来,随着种属间遗传关系的逐渐明晰,分类体系也发生了巨大的改变。当研究者指出小麦属的四倍体和六倍体具有异质、异源多倍体的实质,以及除A染色体组以外所有染色体组都来源于山羊草属(Aegilops)以后,似乎有必要把小麦属和山羊草属合并到同一分类系统中去。Kihara等 Triticum was first classified by Lnne in 1764, and many scholars later revised and innovated it. In the recent fifteen years, with the gradual clarity of the genetic relationships among the species, the classification system has undergone tremendous changes. When the researchers pointed out that the tetraploids and hexaploids of the genus Triticum are heterogeneous, the nature of the allopolyploid, and all the genomes other than the A genome, are derived from Aegilops, it seems necessary Wheat and goat grass merge into the same classification system.
