Chinese Near-isogenic Lines of Rice Applied in Heilongjiang Province Pathogenic Races of Pyricularia grisea Research

In order to seek races of Pyricularia grisea distinction varieties,which adapt research of Heilongjiang Province Pathogenic,Chinese Near-isogenic lines(NILs) of rice applied to the monitoring study in Heilongjiang Province Pathogenic races of Pyricularia grisea for the first time.The analysis of compare Chinese No.1 set 7 distinction varieties with Pathogenic races of Pyricularia grisea proofs that the differentiating ability of Chinese NILs of rice is strongly,they are also playing a part in refining Chinese races of a sort.The study also showed that Chinese NILs of rice are suitable for identificating Heilongjiang rice areas Pathogenic races of Pyricularia grisea.
