| Abstract: | The pathogen of cabbage seeding blight in Harbin City were identified by symptom observation, morphological identification and ITS sequence analysis. A strain RH was isolated and identified by molecular identification as belonging to the anastomosis group AG-4. The results showed that the pathogen causing cabbage seeding blight in Harbin City was Rhizoctonia solani Kühn. The optimum conditions for strain growth were temperature 30 ℃, continuous darkness, pH 8.0, and lethal temperature of 46 ℃, soluble starch, sucrose and peptone, sodium nitrate were beneficial to the growth of the strain. |
