摘要： The photoperiod/temperature-sensitive genic male sterile (P/TGMS) character is important for use of heterosis in hybrid wheat. In the present study, the fertility of 172 doubled haploid (DH) lines derived from the cross between a P/TGMS wheat line BS366 and a restorer wheat line Baiyu149 was investigated under both fertile and sterile environments during three cropping seasons. The phenotype was recorded based on the international seed setting rate. A total of 167 SSR and 1,278 SNP markers were used to construct a linkage map, with a total length of 3,748.94 cM and an average marker interval of 2.59 cM. Three QTLs were identified and designated as QF.bhw-2DS, QF.bhw-4BS and QF.bhw-7Al, explaining 6.9%-12.8%, 19.7%-25.6% and 7.2%-8.8% of the phenotypic variances, respectively. These results lay a good basis for application of male sterility-related molecular markers in improvement of two-line hybrid wheat breeding system.
