Application of SSR Markers in Maize Varietal Identification and Protection

摘要：

Two hundred and twenty-two maize inbred lines and 86 hybrids widely used or being promoted in China were analyzed by SSR (Simple Sequence Repeat). A highly effective, accurate and reliable molecular testing technique system was developed based on the SSR technique. A DNA fingerprinting database of Chinese major hybrids was constructed. A set of core primers was screened and the related PC software was developed to apply in maize varietal identification. The feasibility and future of an established molecular testing system for maize varietal identification and protection is discussed.
