1984～1985年分别在福州金山和莆田市农科所对甘薯资源品种抗瘟性进行鉴定,其结果报道如下:试验方法供试菌株1984年从惠安、龙岩和福鼎等县薯瘟病地采样分离获得pb-hu,ph-yan和pb-J等菌株,通过一套鉴别品种测定,前两者归属菌群Ⅰ,后者归属菌群Ⅱ.菌种存放在4℃冰箱里,使用前经TZC平板纯化后,移到PSA斜面上,经28±1℃温箱里培养36～48小时后,用无菌水配成1.5×10~9菌数/毫升的细菌悬液,供接种用.
1984 ~ 1985 in Fuzhou, Jinshan and Putian City, Agricultural Sciences of sweet potato varieties of blast resistance were identified, the results reported as follows: Test methods Test strains 1984 from Huian, Longyan and Fuding counties and other county sampling and separation Obtained pb-hu, ph-yan and pb-J and other strains, determined by a set of identification varieties, the former two belong to flora I, the latter belongs to flora II strains stored in a refrigerator at 4 ℃ before use by TZC After the plate is purified, it is transferred to the PSA slant surface and incubated in a 28 ± 1 ° C incubator for 36-48 hours. Sterile water is used to prepare a bacterial suspension of 1.5 × 10-9 cells / ml for inoculation.
