摘      要：Pre-harvest sprouting(PHS)is one of the serious global issues in wheat *** of quantitative trait loci(QTL)and closely-linked markers is greatly helpful for wheat *** the present study,a recombinant inbred line(RIL)population derived from the cross of Zhongmai 578(ZM578)/Jimai 22(JM22)and parents were phenotyped in five environments and genotyped by the wheat 50 K single-nucleotide polymorphism(SNP)*** QTL of germination index(GI),***-3A and ***-5A,were detected,explaining 4.33%–5.58%and 4.43%–8.02%of the phenotypic variances,*** resistant effect of ***-3A was contributed by JM22,whereas that of ***.5A was from *** two QTL did not correspond to any previously identified genes or genetic loci for PHSrelated traits according to their locations in the Chinese Spring reference genome,indicating that they are likely to be new loci for PHS *** kompetitive allele-specific PCR(KASP)markers K_AX-109605367and K_AX-179559687 flanking ***-3A,and K_AX-111258240 and K_AX-109402944flanking ***-5A,were developed and validated in a natural population of 100 wheat *** distribution frequency of resistance alleles at ***-3A and ***-5A loci were 82.7%and57.1%,respectively,in the natural *** findings provide new QTL and tightly linked KASP markers for improvement of PHS resistance in wheat.
