太谷核不育小麦是一个十分有用的遗传改良工具,现在已广泛用于我国的小麦育种实践。它的显性不育基因位于4D染色体上的事实,似乎限制了这个基因在硬粒小麦、圆锥小麦和六倍体小黑麦中的应用。这些物种4D单体附加系的产生,有可能打开小麦显性不育基因应用于这些物种的大门。
Taigu nuclear sterile wheat is a very useful genetic improvement tool, which is now widely used in the practice of wheat breeding in our country. The fact that its dominant sterility gene is located on chromosome 4D seems to limit the use of this gene in Durum, Cone and Hexaploid Triticale. The production of these 4D monomeric additional lines may open the door for the dominant gene of wheat to be applied to these species.

初秋的一天，天气还没有丝毫的凉意，在美国落基山麓一处人工滑冰场上，马上要进行一场滑冰比赛。看台上人头攒动、座无虚席，大家正在焦急地等待着，并七嘴八舌地议论着：“没有冰，在哪儿比赛呀？”话音未落，只见十几个工作人员走了过来，他们有的洒水，有的往运动场上打气，只是眨眼的功夫，奇迹便出现了，运动场上已结了一层厚厚的冰。滑冰比赛马上就可以进行，真是太神奇了。这究竟是怎么回事呢？原来，工作人员用气筒喷洒的是
