Grate sieve for screening rice blast resistant materials and application of grate sieve

The invention discloses a grate sieve for screening rice blast (gene) resistant materials and application of the grate sieve, and belongs to the technical field of resistance breeding. The standard dominant avirulent gene strain grate corresponding to the rice blast resistance gene is screened out through a large number of experiments, the rice blast resistance pressure can be directionally given to rice, the specific rice blast resistance rice variety (material) is screened out, and a foundation is laid for rice blast broad-spectrum resistance breeding. 本发明公开了一种筛选抗稻瘟病(基因)材料的篦子筛及其应用，属于抗性育种技术领域。本申请通过大量实验筛选出与稻瘟病抗病基因对应的标准的优势无毒基因菌株篦子，能够定向给予水稻稻瘟病抗性压力，筛选出特定的稻瘟病抗性水稻品种(材料)，为水稻稻瘟病广谱抗性育种打下基础。
