To clarify the genetic mechanisms of fertility restoration in sorghum F 1 hybrids produced in Japan ('Ryokuryu', 'Hazuki', 'Haretaka', 'Natsuibuki', 'Hanaaoba', 'Akidachi' and 'Kazetachi'), we analyzed QTLs for fertility restoration using seven F 2 populations derived from those hybrids. By QTL mapping with a series of SSR markers, we detected three major QTLs for fertility restoration. These data and the results of haplotype analysis of known fertility restorer ( Rf ) genes showed that qRf5 , corresponding to the Rf5 locus, was the most widely used Rf gene for fertility restoration of sorghum F 1 hybrids among the lines tested. Other major Rf genes detected were qRf8 , corresponding to Rf1 , and qRf2 , corresponding to Rf2 . QTLs for grain weight also corresponded to these Rf loci. A minor QTL, qRf3 , may also affect restoration of fertility. Our data show that three major Rf s- Rf1 , Rf2 , and Rf5 -were used in F 1 hybrid sorghum production in Japan. This knowledge can be used to improve the efficiency of the F 1 sorghum breeding program.
