六十年代以来,用辐射和化学诱变剂诱发出的矮秆小麦新品种相继在生产上推广。实践证明,突变育种方法能够诱发小麦的矮秆抗倒伏变异,而且突变率高。用这个方法可以改造当地品种秆高易倒伏的缺点,而保持原品种的其它优良特征。它是一种较快速而有效的育种途径。 Since the 1960s, new varieties of dwarf wheat induced by radiation and chemical mutagens have been successively promoted in production. Practice has proved that mutation breeding methods can induce dwarf lodging resistance of wheat, and the mutation rate. This method can be used to transform the shortcomings of local breeds with high susceptibility to lodging while maintaining other excellent characteristics of the original breed. It is a faster and more effective breeding method.
