主　　题：Rapeseed Target capture SNP genotyping platform Genomic breeding 

摘      要：Rapeseed(Brassica napus)is an oil crop grown worldwide,making it a key plant species in molecular breeding ***,the complexity of its polyploid genome increases sequencing costs and reduces sequencing *** capture coupled with high-throughput sequencing is an efficient approach for detecting genetic variation at genomic regions or loci of *** this study,588 resequenced accessions of rapeseed were used to develop a target capture sequencing SNP genotyping platform named *** platform comprised 54,765,with 54,058 resequenced markers from the pan-genome,and 855 variant trait-associated markers for 12 agronomic *** capture quality of BnaPan50T was demonstrated well in 12 typical *** with a conventional genotyping array,BnaPan50T has a high SNP density and a high proportion of SNPs in unique physical positions and in annotated functional genes,promising wide *** capture sequencing and wholegenome resequencing in 90 doubled-haploid lines yielded 60%specificity,78%uniformity within tenfold coverage range,and 93%genotyping accuracy for the ***50T was used to construct a genetic map for quantitative trait loci(QTL)mapping,identify 21 unique QTL,and predict several candidate genes for yield-related traits in multiple environments.A set of 132 core SNP loci was selected from BnaPan50T to construct DNA fingerprints and germplasm identification *** study provides genomics resources to support target capture sequencing,genetic analysis and genomic breeding of rapeseed.
