Resistance Identification of Different Asparagus Varieties to Stem Blight Disease and Comparison of Their Agronomic Traits

To screen asparagus varieties which have resistance to stem blight and good agronomic traits in seedling period,nine asparagus varieties were tested.Our results showed that Xinwangchao F1,Jinglvlu No.1 and SD 09-6 are resistant to stem blight disease,and the germination rate of Xinwangchao F1,De Paoli F1,Green Tower and UC157 F2 are higher and reach 85.33%.Meanwhile,the agronomic characters of Xinwangchao F1,Jinglvlu No.1,TC,SD 09-6 and UC157 F2 were the best.
