| 摘 要： | 温室和田间鉴定19个白菜品种和品系对萝卜蚜的抗性,结果表明,金边白菜和上海白菜2个品种表现为抗虫。蚜虫在抗虫品种上,取食量明显低于感虫品种,发育速度缓慢,繁殖力低,结果在植株上产生较小的虫群,说明了这两个品种的抗虫机制为抗生性,田间试验证明抗蚜品种花叶病发病率低。

| Abstract: | The resistance of Brassica chinensis to the turnip aphid was evaluated by using the seedling bulk screening test in the greenhouse and the field.Among the 19 varieties (lines) tested,Jinbianbai and Shanghaibai were resistant.When the aphids fed on these,they showed lower food uptake and fecundity,slower development,and smaller population growth as compared to when they fed on the susceptible varieties,indicating the presence of antibiotic factors.Also the aphid-resistant varieties exhibited resistance to the mosaic virus disease. |
