摘　　要：抗除草剂水稻品种的推广应用可解决田间杂草、杂草稻,提高杂交稻纯度等生产实践问题。本研究利用咪唑啉酮类除草剂,以70 g/hm2使用量,配制咪草烟的水剂,在水稻生长到2叶1心时进行喷雾除草,从7 403份水稻品种资源中,获得1份抗咪草烟的水稻新资源。Application of herbicide-resistant rice varieties is beneficial for improving the production problems of rice,including the disaster of the weed,weedy rice and the confounding of the faking hybrid seed.However,few herbicide-resistant rice germplasm had been found.In this study,the authors screened 7,403 rice collections varieties by imazapic(70 g/hm^2)spraying treatment at 2~3 leaves stage,and successfully obtained 1 new imazethapyr-resistance rice germplasm.
