摘　　要：应用紫外线和叠氮化钠对小麦种子进行诱变,在含有不同浓度草甘膦中进行种子筛选。在40mL/L草甘膦筛选条件下,经过紫外线照射不同时间(0.5h、1h、1.5h)诱变筛选出22粒小麦种子,经5mmol/L叠氮化钠浸泡不同时间(1h、2h、3h),筛选出19粒种子。将所筛选出的种子苗期进行40mL/L草甘膦筛选,筛选出4株抗草甘膦的小麦植株。The wheat seeds were mutated with ultraviolet rays or NaN3 and selected in glyphosate with different concentration. 22 Seeds were obtained with ultraviolet rays （0.5 h, 1 h, 1.5 h） mutation and 19 seeds with 5 mmol/L NaN3 （1 h, 2 h, 3h） mutation in 40 mL/L glyphosate. The selected seeds were planted and the seedlings were treated with 40 mL/L glyphosate, then obtained 4 glyphosate-resistant wheat plants.
