摘要：為創(chuàng)制結(jié)球菊苣新種質(zhì)，本研究建立了結(jié)球菊苣EMS誘變技術(shù)體系。結(jié)果表明，在EMS濃度0.8%、處理6 h時(shí)，相對(duì)發(fā)芽率接近半致死率，誘導(dǎo)效果最好，種子發(fā)芽生長狀況良好，被確定為結(jié)球菊苣EMS誘變最佳處理?xiàng)l件。研究結(jié)果為結(jié)球菊苣突變體庫構(gòu)建及新品種選育提供參考依據(jù)。

Abstract： In order to create new germplasm of leaf chicory， this article established an EMS mutagenesis technology system for leaf chicory. The results showed that at an EMS concentration of 0.8% and treatment for 6 h， the relative germination rate was close to the half lethal rate， and the induction effect was the best. The seed germination and growth conditions were good， and it was determined as the optimal treatment condition for EMS mutagenesis of leaf chicory. This study established an EMS mutagenesis technology system for leaf chicory， and the research results provide a reference for the construction of a leaf chicory mutant library and the breeding of new varieties.

Keywords： leaf chicory; EMS; mutagenesis technology
