摘要: 为了加快木薯优良品种选育进程,笔者简述了近年来国内外木薯诱变育种的研究进展。重点归纳了木薯诱变材料的选择、诱变方法、诱变方式、木薯诱变效应及突变体的鉴定、筛选及嵌合体的分离策略等方面,同时提出了目前木薯诱变育种存在的突变随机性和嵌合体等问题及解决方案。指出如何建立一套高效的诱变育种技术将是一个关键的问题。另外笔者认为诱变育种技术与离体技术、生物技术结合将是今后木薯研究的重点.

Abstract: In order to speed up the process of cassava varieties breeding, the author briefly reviewed the advances in research on mutation breeding of cassava at home and abroad. Various factors such as selection of explants , mutagenesis method, mutation of the way, mutagenic effect of cassava, the identification of mutant, screening of mutants and the isolation of chimeric strategy were emphatically analyzed. It also has some problems of Mutation of randomness , chimeras and solution. So how to establish a high efficient system for mutation breeding of cassava is the key problem. And Mutation breeding technology and the combination of in vitro culture technology and biotechnology will be the research emphases in future.
