生物育种技术促进甜菜种质资源创新研究进展OA

To strengthen the national sugar security line and solve the core industrial problem of sugar beet germplasm resource innovation,this article systematically conducts a comprehensive review on sugar beet biotechnology breeding.It summarizes the application status and research progress of four major biotechnology breeding techniques(molecular marker technology,transgenic technology,gene editing technology,and tissue culture technology)in the innovation of sugar beet germplasm resources;it concludes the practical achievements of various technologies in the improvement of sugar beet quality,the breeding of disease and stress resistance,the rapid propagation of germplasm,and the creation of new germplasm;it reveals several prominent issues existing in the innovation of Chinese sugar beet germplasm resources,including weak genetic foundation,low efficiency of technology transfer,intensification of biotic and abiotic stresses,insufficient policy and human resource support,and low industrial benefits;it proposes the following countermeasures and suggestions:integrating multiple technologies to build a complete breeding system,exploring wild germplasm to broaden the genetic background,conducting targeted improvement of multiple resistances and excellent quality,and deepening collaborative innovation among industry,academia and research institutions.It is believed that biotechnology breeding techniques are the core support for the precise and efficient innovation of sugar beet germplasm resources.It is pointed out that in the future,a national integrated germplasm innovation platform needs to be established,and key bottlenecks in genetic transformation technology must be broken through,in order to achieve the independent control of China's sugar beet seed industry and the high-quality development of the industry.
