PRELIMINARY STUDY ON THE APPLICATION OF GENE EDITING TECHNOLOGY IN RAPESEED QUALITY IMPROVEMENT
ABSTRACT
This paper explores gene editing technology, including its development, working principle, especially the CRISPR-Cas 9 system. This technique enables a customized modification of the genetic code through precise genetic mapping and DNA repair, which has important implications for agricultural genetic improvement. In terms of rapeseed quality improvement, gene editing technology shows great potential, improving oil content, optimizing quality characteristics, and enhancing the ability to resist pests and diseases, while reducing harmful substances. It also promotes the breeding and industrialization of new rapeseed varieties. Despite the technical precision, operation complexity, food safety, regulatory lag and costly challenges, this paper puts forward to strengthen training, multi-point editing technology, standardized process strategy, and suggested to strengthen the safety assessment, perfect laws and regulations and government funds, to ensure the safe, efficient and sustainable development of technology.
