摘　　要：化学诱变因其点突变比例和突变频率高、特异性强等特点,被广泛应用于诱发育种。近年来,用此方法获得的突变材料,成为基因组学等研究的重要基础,进而成为研究热点。文章介绍了化学诱变的特点与发展历史,总结分析了诱变材料、诱变剂种类以及诱变方法如浓度、时间、温度等对诱变效率的影响,综述了化学诱变技术在国内外蔬菜育种研究中的进展及成果。Chemical mutagenesis is widely used in induced breeding because of its high point mutation probability,high mutation frequency,and strong specificity.In recent years,the materials based on chemical mutagenesis become popular in the field of genomics and other researches.This study introduced the characteristics and development history of chemical mutagenesis,summarized the influence of the mutation materials,mutagen types and mutation methods,such as concentration,time,and temperature on the mutation efficiencies.The progress of chemical mutagenesis technology in vegetable breeding worldwide and its achievements were presented as well.
