选育抗瘟性强且抗性相对稳定的新品种是解决稻瘟病危害的最佳途径。由于条件所限，这种抗瘟性强且抗性相对稳定的稳产型品种的选育难度较大。针对这一问题我们做了大量的研究工作，通过试验提出了“不同抗瘟类型品种（系）混植组合体”的概念及其选育程序和方法。 Breeding new varieties with strong anti-blast and relatively stable resistance is the best way to solve the hazard of rice blast. Due to the limited conditions, it is more difficult to select a stable yield variety with strong resistance to blast and relatively stable resistance. In response to this problem, we have done a lot of research work, and put forward the concept of “different types of plants (lines) mixed with different blast types” and the breeding programs and methods through experiments.
