Maize Rough Dwarf Disease (MRDD) caused by maize rough dwarf virus (MRDV) is a worldwide disease. It is one of the most serious diseases in maize-growing area of China. Developing and cultivating resistant hybrids is an effective approach to control MRDD. However, a few resistance germplasm are identified so far. In this study, identification of resistant materials, development of molecular markers and QTL analysis were investigated. The results as follows:
1. 200 maize inbred lines for MRDD resistance ...
