摘要
[目的]筛选出抗芜菁花叶病毒(Tu MV)的白菜种质资源。[方法]选取8份白菜高代自交系种质材料,在3叶期人工磨擦接种Tu MV-C4株系,进行抗/感病表型调查、d CAPS功能标记筛选以及ELISA试验鉴定。[结果]1600011-1、1600043-3、1600045-3和1600331-3为Tu MV感病材料;1600031-2、1600067-2、1600105-1和1600485-2为Tu MV抗病材料。[结论 ]研究鉴定了大白菜抗Tu MV的性状,为大白菜抗Tu MV育种提供了抗源材料。
[Objective] In order to screen germplasm resources resistant to Turnip mosaic virus(Tu MV)in Chinese cabbage. [Method] Eight Chinese cabbage highly inbred lines were inoculated with Tu MV-C4 isolate to screen the resistance lines,when the plants were at 3-leave stage.[Result] Thronging phenotype investigating,d CAPS marker screening,and the ELISA assay identifying,it confirmed that the four lines:1600011-1、1600043-3、1600045-3 and 1600331-3 were susceptible materials, and the four lines:1600031-2、1600067-2、1600105-1 and 1600485-2 were resistant materials. [Conclusion] The study screened the germplasm resources resistant to Tu MV in Chinese cabbage using three methods,and provided the resistance materials for resistance Tu MV breeding.
