水稻育种使用的技术路线与方法有很多种,比如杂交育种、辐射育种、轮回选择育种以及目前比较前沿的分子育种等,这些育种方法在水稻育种史上都取得了一定的成就。但是目前品种同质化比较严重,其潜力已经挖掘到一定程度,难有大的突破。目前粳稻品种所面临共同的不足点如抗耐性、抗病虫害、抗寒性等,再运用常规育种手段难以有所突破。所以在目前的形势下,有必要运用新的手段将丰富的种质利用起来,打破亚种和亚种之间、种群和种群之间的不亲和性,有效的聚合优
There are many technical routes and methods used in rice breeding, such as hybrid breeding, radiation breeding, selective breeding and the current cutting-edge molecular breeding, etc. These breeding methods have made some achievements in the history of rice breeding. However, the current varieties of homogenization more serious, its potential has been tapped to a certain extent, difficult to have a major breakthrough. At present, common shortcomings such as resistance, pest resistance, cold resistance and so on are encountered in japonica rice varieties, and then it is difficult to break through the conventional breeding methods. Therefore, in the current situation, it is necessary to utilize new means to utilize abundant germplasm to break the incompatibility between subspecies and subspecies, population and population, and to effectively polymerize
