One hundred RAPD primers were used to amplify true and false hybrid rice ⅡYou 63 genomic DNAs in this experiment. The main DNA polymorphisms from the two materials were not found, indicating that true and fasle ⅡYou 63 genetic background are similar. However, we had established a PCR system which can be used to determine the seed purity of Shanyou 63 by using a primer P18 to amplify a specific band of 0. 8 kb from restorer line Minghui 63. This technique can also be used to determine true and false ⅡYou 63 correctly and fast, verifying that the Shanyou 63 PCR system is suitable to determine true and false hybrid rices using Minghui 63 as restorer line.
