| 摘 要： | 应用染色体组分析法,对几个中国特有普通小麦的起源问题作了初步探讨。结果表明:中国特有普通小麦与斯卑尔脱小麦有1—2对染体差异较大。中国特有普通小麦可分为新疆稻麦与云南铁壳麦、西藏半野生小麦、“四川白麦子”两个独立类群;类群间在B组有2对染体存在差异,其中1对可以确定为6B。两个类群可能起源于中国,分而于新疆及黄河中游地区的节节麦可能是D组供体。

| Abstract: | Genome analysis showes. that special kinds of hexaploid wheats (Triticum aestivum L. ) from China are quite different from the T. aestivum L. concv, spelta, and can be classfied into two independent groups, i.e.: (a) Tibetan weedrace of hexaploid wheat, Yunnan hulled wheat and Sichuan white wheat complex (including CS) and (b) Xinjiang rice wheat. There are 2 pairs of different chromosomes between groups, one of which was identified as 6B. In the cytogenetic point of view, the two groups of special hexaploid wheats probably originated in China, and the Aegilops tauschii Cosson which distributes in China, may be the D genome donor of the special hexaploid wheats. |
