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/hm2) spraying treatment at 2 ~3 leaves stage, and successfully obtained 1 new imazethapyr-resistance rice germplasm.
