小麦属物种的分类,世界上学者们的见解不尽相同。目前,我国一般采用苏联道罗费耶夫的方法。道罗费耶夫(1979年)根据长期对世界各地的大量小麦遗传资源细胞学、遗传学等的研究结果,将小麦分为两个亚属即小麦亚属和野生一粒亚属。小麦亚属的基础是A~u染色体组的携带者乌拉尔图小麦,所有含A~u染色体组的种,叶片上都有短而柔软的绒毛;而野生一粒亚属的基础是A~b染色体组的携带者野生一粒小麦,凡具有A~b染色体组的种,叶片上有较长而粗糙的刚毛。在亚属内划分为系(或组),系下分若干物种。小麦亚属内分为3个系19个种,即乌拉尔图系(乌拉尔图小麦),二粒系(野生二粒小麦、栽培二粒小麦、伊斯帕汗小
The classification of wheat genus species, the views of scholars in the world vary. At present, our country generally adopts the method of the Soviet Union Droeyev. Droeyev (1979) divides the wheat into two subgenuses, Triticum and Genus, based on the long-term findings of the numerous cytogenetic and genetic studies of wheat genetic resources around the world. Wheat subgenus is based on the A ~ u chromosome group carriers Ural Figure wheat, all with A ~ u chromosome group species, the leaves have short and soft villi; and a wild subgenus is based on A ~ b Chromosome group of carriers of a wild wheat, who have A ~ b genome group species, leaves longer and rough bristles. In subgenus is divided into departments (or groups), the Department of several species under the points. The wheat subgenus is divided into three families of 19 species, namely the Urals diagram (Ural diagram wheat), two lines (wild two wheat, two wheat cultivated, Ispa Khan small
