| Abstract: | Downy mildew is one of the most destructive diseases of maize in the world. Especially, this disease causes huge losses to maize production frequently both in tropical and in subtropical. In this paper we summarized the progress on molecular and genetic studies of maize downy mildew including genetic behave of resistance, QTL location of resistant gene, QTL effects and interactions between QTLs and environments, molecular marker and genetic diversity of resistance to maize downy mildew. In the last, the authors expected the importance on resistant gene clone, construction of NILs and the system establishment of MAS in the future. |
