黑龙江省水稻稻瘟病研究现状及抗病育种

Resistance breeding and research status of rice blast in Heilongjiang Province

对黑龙江省水稻稻瘟病的研究进展情况进行综述,着重在稻瘟病优势生理小种的变化动态、抗性基因、无毒基因、抗病品种研究等方面进行了总结,并简要提出了黑龙江省稻瘟病研究及抗病育种的未来发展方向。

Rice blast is the most important disease of rice in Heilongjiang Province, which affects the steady development of rice industry. Dynamic of rice blast pathogen （Magnaporthe grisea）, resistance genes, avirulence genes,development of resistant varieties were reviewed in this paper. Future development direction in studies on rice blast and resistance breeding in Heilongjiang Province were also discussed in this paper to provide reference for further research of rice blast in Heilongjiang Province and breeding for disease resistance.
