In this study, two rice BAC clones closely linked to rice gall midge resistance, Gm-2 and Gm-6, were in situ hybridized to Oryza officinalis chromosomes. They were located on the long arm of chromosome 4 with FL 72.33% and 77. 10% respectively and their FL was consistent with the selective marker of rice, RG214 and RZ569. The frequency of signal detection was 61.2% and 59.5% respectively. Our study was based on comparative RFLP map of wild rice, O. officinalis, and cultivated rice, O.sativa.展开更多
