摘要

[Objectives] This study was conducted to investigate the possibility of screening for herbicide resistance in the early stage of rapes growth. [Methods] Eight treatments were set for a herbicide concentration experiment. [Results] Rape sprouts were highly sensitive to the herbicide glyphosate, and even a very low concentration of glyphosate solution(187 mg/L) was sufficient to kill most of the rape seedlings, while the genetically modified herbicide-tolerant rape could tolerate higher concentrations of the herbicide. Low concentrations of glyphosate could be used for screening at the sprout stage, and the results of herbicide-tolerance screening were consistent with PCR testing. [Conclusions] This study lays a technical and material foundation for accelerating the cultivation of new herbicide-resistant rape varieties suitable for rapeseed production areas in the lower reaches of the Yangtze River.
