主 题：breeding germplasm signature
摘 要：Cucumber selective breeding over recent decades has dramatically increased productivity and quality,but the genomic characterizations and changes associated with this breeding history remain ***,we analyzed the genome resequencing data of 56 artificially selected cucumber inbred lines that exhibit various phenotypes to detect trait-associated sequence variations that reflect breeding *** found that the 56 cucumber lines could be assigned to group 1 and group 2,and the two groups formed a distinctive genetic structure due to the breeding history involving hybridization and *** selected regions were identified between group 1 and group 2,with implications for genomic-selection breeding *** regions included known quantitative trait loci or genes that were reported to be associated with agronomic *** results advance knowledge of cucumber genomics,and the 56 selected inbred lines could be good germplasm resources for breeding.
