Rapid constructing a genetic linkage map by AFLP technique and mapping a new gene tms5

In this study, we reported the repaid construction of a molecular marker linkage map of rice (Oryza sativa L. ). An F₂ population from the cross between Annong S-1 and Nanjing 11 was used to construct a genetic linkage map of rice. Total of 142 newly screened AFLP markers and 30 anchor markers (25 SSR markers and 5 RFLP markers) were mapped on the 12 chromosomes covering 1 537.4 cM of rice genome. The average interval between these markets was 9.0 cM. The total work which usually was finished in more than one year was finished within only 3 months by one person. This is the first plant AFLP map developed in China. A new thermosensitive genic male sterile gene in rice, tms5, was tigged and mapped onto chromosome 2 during the development of the linkage map.
