Rice planting is an important grain planting project in China. It plays an important role in ensuring food supply. In order to continuously improve the yield and quality of rice planting in China, the new era puts forward higher requirements for rice breeding. In general, rice breeding mainly focuses on yield, quality, resistance to pests and diseases, and resistance to stress, but without the support of breeding materials, rice breeding work is difficult to carry out, so the use of germplasm resources and other equipment to preserve species The quality of resources is to accumulate raw materials for the breeding of rice and other crops, and to provide support for the development of rice breeding.
Germplasm resources are important scientific and technological equipment for storing germplasm resources. There are two main functions. The first is to create environmental conditions, to store all kinds of germplasm resources collected in a safe and long-term manner, and the second is to use the system platform. The germplasm resources in storage are classified and organized to achieve more effective development and utilization. As of 2017, China's national genebank has preserved 84,935 rice germplasm resources, of which local rice species accounted for the highest proportion, with 51,501. These collected rice germplasm resources have made outstanding contributions to the breeding of new rice varieties and industrial development.
Although China has abundant rice germplasm resources, due to environmental changes and the impact of human activities, more and more rice germplasm resources have experienced a crisis of survival and are at risk of disappearing. At this stage, germplasm resources The development and utilization rate is not high. Therefore, the main work at this stage is to collect and protect these endangered rice germplasm resources through the construction of germplasm resources, so that they can continue to serve modern agricultural development. With germplasm resources, the next step is how to use it effectively. With the increasingly close cooperation and exchange of resources and breeding and seed industry, it will promote the sustainable development of rice breeding in China and make positive contributions to food security.
