摘要: This study evaluated the genotyping by sequencing (GBS) protocol for fingerprinting Brassica rapa, and the data derived were more reliable than the re-sequencing data of B. rapa. Of the 10 enzyme solutions used to analyze the numbers of genotypes and single-nucleotide polymorphisms (SNPs) in B. rapa, five solutions showed better results, namely, A (HaeIII, 450-500 bp), E (RsaI+HaeIII, 500-550 bp), F (RsaI+HaeIII, 500-600 bp), G (RsaI+HaeIII, 'All' fragment), and J (RsaI+EcoRV-HFV (R), 'All' fragment). The five enzyme solutions showed less than 40% similarity in different individuals from various samples, and 90% similarity between two individuals from one sample. The E enzyme solution was the most suitable for fingerprinting B. rapa, revealing well-distributed SNPs in the whole genome. Of the 82 highly inbred lines and 18 F-1 lines of B. rapa sequenced by GBS in the E enzyme solution, known parents of 10 F-1 lines were verified, and male parents were discovered for 8 F-1 lines that had only known female parents. This study provides a valuable method for screening parents for F-1 lines in B. rapa for the efficient evaluation of GBS with varied library construction strategies.
