摘要:

【目的】研究小麦品种衡观35抗茎基腐病EMS突变及其鉴定。【方法】利用不同浓度的甲基磺酸乙酯(EMS),对小麦品种衡观35进行诱变,以未经诱变的衡观35为感病对照,以石优17为中度抗病对照。人工接种假禾谷镰刀菌,对诱变材料进行抗性鉴定,经温室加代获得抗茎基腐病M3代材料。【结果】适于衡观35突变的EMS浓度为0.4%,并且从106株M3衡观35材料中获得7株期表现免疫的突变株,突变体材料苗期和成株期整体病情指数比感病对照分别降低34.93%和34.62%。【结论】EMS突变小麦衡观35,适宜的突变浓度为0.4%,共从供试突变品种M3代中筛选获得了7份免疫的抗小麦茎基腐病的资源。

Abstract:

【Objective】 Study EMS mutants of wheat hengguan 35 and identification of the mutants resistant to fusarium crown rot.【Methods】 In this study, different concentrations of ethyl methanesul fonate (EMS) were employed on wheat seeds of cultivar Hengguan 35.The untreated Hengguan 35 was used as the susceptible control, and Shiyou 17 was used as the moderately resistant control.Through artificial inoculation of Fusarium pseudograminearum, the resistance of the mutagenized material was identified, and the M3 generation material resistant to FCR was obtained by adding generation in the greenhouse.【Results】 The EMS concentration suitable for Hengguan 35 mutation was finally determined to be 0.4%, and seven mutants showing immunity at the plant stage were obtained from 106 M3 Hengguan 35 materials.The overall disease index of the mutant materials at seedling and adult stages was 34.93% and 34.62% lower than those of the susceptible control, respectively.【Conclusion】 After EMS mutation of wheat Hengguan 35, an appropriate mutation concentration of 0.4% was determined. A total of 7 immune resistant wheat FCR were screened from the M3 generation of the tested mutant varieties.
