Abstract:

Wheat blast, caused by Pyricularia oryzae (syn.Magnaporthe oryzae), had an outbreak in Brazil in 1985 and spreaded to neighboring countries soon. In 2016 and 2017, a severe outbreak happened in Bangladesh and India, respectively, whcih has caused severe impacts on local wheat yield and economics. There is no effective controlling measure at present, thus breeding for resistance is an alternative, environmentally friendly method to control blast disease. And we found the MoO pathotype of P.oryzae could infect wheat via lab inoculation. In this paper, we deem that wheat blast did not been found in China yet, but China is at increased risk for the overwhelming wheat blast since global warming continues. Thus we still need to pay great attention to it, and we should strengthen cooperation and communication with international wheat blast researchers. In addition, we also introduce inoculated methods to identify resistance genes in both seedling and heading stages, which will contribute to identification of resistance genes in wheat accessions of China, providing a reference for resistance breeding and further researches.

Key words: wheat blast, Pyricularia oryzae, resistance genes, interaction, identified method
