摘　　要：甲基磺酸乙酯(EMS)作为化学诱变剂,由于具有诱变率高的特点,已被广泛应用于玉米诱变育种,成为玉米种质创新和自交系改良的有效工具之一。本文对EMS诱变玉米花粉的作用机理、诱变处理技术、诱变后代所产生的突变性状,及EMS诱变在玉米育种中的应用进行了概述。Ethylmethane sulphonate （EMS）, an effective chemical mutagen, has widely been used in mutation breeding of maize. EMS mutation method, has character of high mutation rate, has been an effective tool in maize germplasm creation and improvement. The mechanism of EMS mutagenesis maize pollen, mu- tation processing technology, characteristics of mutagenic offspring and its application in maize breeding were briefly introduced in the paper.
