Abstract:: By using tissue isolation method and the traditional morphological identification method to discover the pathogen causing Fusarium wilt disease on edible lily,and then the disease resistance of different edible lily germplasm resources was identified by scale inoculation and detached leaves after inoculating pathogen，in order to screen out the strong resistance to consumption of lily species and varieties.The results showed that Fusarium oxysporum was the main pathogen of edible lily wilt disease;the results of identification of scale inoculation was L.davidii var.unicolor was high resistance,Lilium longiflorum,L.lancifolium,‘Guangxi’ lily,‘Liupian’ lily were middle resistance,‘Tiantaishan’ lily,‘Zhongpian’ lily,‘Gaopian’ lily,‘Ji′an Longya’ were middle sense;the results of resistant identification by the method of inoculating pathogen on leaves in vitro were Lilium brownii var.viridulum,L.lancifolium were middle resistence,L.davidii var.unicolor was middle sense,seven other kinds of ‘Longya’ lily were all high sense.
