In view of the increasingly serious problem of the endangered status of wild rice in Guangxi, the rescue collection of wild rice-rich areas in Guangxi was carried out, and the resistance identification of bacterial blight and rice blast was carried out. According to the distribution area and density of wild rice, the 44 originally recorded distribution sites in the survey results of wild rice in Guangxi are divided into four levels: extinction, endangered, vulnerable and least concerned, and found that 45% populations have been in extinction. 7% populations were endangered, and 25% populations were classified as vulnerable, and the other 23% populations could be classified as Least Concerned. A total of 317 wild rice germplasm resources were collected from 11 populations of Oryza rufipogon Griff. and Oryza officinalis Wall. The resistance to bacterial blight was identified by using the international virulent strain PXO99, and the resistance to rice blast of different isolates ( Guy11, RB22, FJ-3-2, FJ-3-5, FJ-2-3 ) was identified by wounding detached rice leaf. The results showed that 27 bacterial blight resistance resources, 105 rice blast resistance resources, and 5 resources with both bacterial blight and rice blast resistance were identified from 177 wild rice. In view of the problem that the disease-resistant resources of wild rice in Guangxi are rich but disappear seriously, it is suggested to strengthen the collection and protection, and increase the identification of germplasm resources.
