Abstract:Advance in the molecular characteristics and strain differentiation of turnip mosaic virus (TuMV) , the inheritance and molecularmarker of TuMV-resistance in Brassica crop s, creation of new germplasm by transformation, the screening of TuMV-resistance and the breeding of new cultivars with TuMV-resistance were reviewed in this paper. The problems to be solved and prospects of TuMV-resistance breeding were discussed.
