Abstract: Purity is an important parameter of seed quality. ‘Jixiang No 1’ is a main maize hybrid variety and widely cultivated in Gansu Province. To identify the purity of the variety, the authors conducted a research on SSR purity identification method of ‘Jixiang No 1’. Through the comparison of rapid extraction method and improved CTAB method used in the purity test of ‘Jixiang No 1’ with SSR marker, the results showed that the DNA extracted by the above two methods was applicable to the purity detection of SSR molecular markers, but the rapid extraction method had the characteristics of simple, fast, and was more suitable for the purity identification. bnlg2291k4 and bnlg2305k4 were selected from 20 pairs of SSR markers for purity test of ‘Jixiang No 1’, both markers could clearly distinguish parents and hybrids. Mixing parents seeds into hybrid seeds of ‘Jixiang No 1’, the method established by this study could clearly identify inbred lines.
