| Research Abstract |
To elucidate the mechanism of paternal inheritance of rapeseed mitochondrial plasmid, I conducted the QTL analysis. Using the the F2 population (102 individuals) derived from the cross rapeseed varieties with different plasmid transfer rate, "Norin 16" and "Westar", genetic map covering 1374.7 cM was constructed and then three QTLs were detected on the chromosomes, C2, C9 and A5. These results indicated that the paternally inheritance of mitochondrial plasmid is controlled by relatively a few nuclear genes.
