通过细胞突变体筛选创造抗 (耐 )除草剂作物新品种的操作技术 ,包括基础材料的筛选、抗药性遗传规律研究、突变体筛选、后代培育等过程 ,适用于小麦、玉米、谷子、大豆等作物 ,一般 4～ 5a可望选育出抗除草剂的品种或新种质。根据这个思路 ,用这项技术选育抗莠去津小麦新种质的实践 ,现已获得能够抗 (耐 ) 10 0～ 2 0 0mg/L莠去津的小麦细胞突变体和再生植株 ,并得到 2 0 0多份对莠去津具有抗 (耐 )性的无性系 ,目前正在进一步回交转育和鉴定中 Screening of Cell Variants to Create New Varieties of Anti-Herbicide Resistant Crops Techniques including screening of basic materials, genetic studies on drug resistance, screening of mutants, breeding of offspring, etc. are suitable for use in wheat, corn, millet, soybeans, etc. Crops, generally 4 ~ 5a is expected to breed resistant varieties or new germplasm. According to this idea, the technology of breeding atrazine new wheat germplasm practice has been able to (resistant) 10 0 ~ 200mg / L atrazine in wheat cell mutants and regenerated plants, and Over 200 clones resistant to atrazine have been obtained and are currently being backcrossed and identified
