摘要
The inheritance of fertility restoration of rice cytoplasmic male sterility of the wild abortive type was studied by means of QTL mapping. The two segregating populations examined showed high frequencies of highly sterile and highly fertile progenies, but a low frequency of partially sterile and partially fertile progenies. The distributions suggested that fertility restoration was mainly controlled by major genes. Based on a linkage map constructed with 57 RFLP and 61 AFLP markers on a B1F1 population, composite interval mapping (CIM) revealed that the fertility was restored by the additive effects of two restorer loci located on chromosome 10. One QTL, tightly linked to RFLP marker C1361 in the middle of the long arm of chromosome 10, explained 71.5% of the phenotypic variance. The second QTL was located between RFLP markers R2309 and RG257 on the short arm and explained 27.3% of the phenotypic variance. Similar results were obtained using the simple interval mapping (SIM) methods.
