Title: Study on the race and biovar of the pathogen of mulberry bacterial wilt in Zhejang
Abstract: Two hundred and seventeen bacterial strains of Ralstonia solanacearum were isolated from the xylem and phloem of roots and stems infested by mulberry bacterial wilt in Lingan and Tonglu counties in Zhejiang province.Sixteen typical strains from 217 bacterial strains were studied.The pathogenicity test found that they could cause the wilt of mulberry and were the similar to that of R.solanacearum of tomoto in shape,size,dye-reaction etc.Accoding to Haywind's classification criterion of R.solanacearum,the strains were classified as the physiological race 1.Biochemistry test of the strains showed that 75% of R.solanacearum was biovar Ⅴ,25% of R.solanacearum was biovar Ⅲ.
