Genetic Diversity Analysis of Non-Heading Chinese Cabbage of Resistance to Clubroot Disease Based on SNP Molecular Markers

Clubroot disease is a kind of soil-borne that seriously infects Brassica species. In this study, we collected 121 varieties non-heading Chinese cabbages. order to better understand the genetic variation and screen suitable clubroot disease-resistant parental material, re-sequenced them examine population structure, diversity, differentiation index, selective sweep based on SNPs. The mapping rate with reference genome was high, data quality analysis revealed sequencing good. annotated indicated intronic intergenic areas held majority SNPs indels. Four subgroups cabbages were identified using principal component analysis, phylogenetic tree, structure analysis. An examination diversity while selfing may happen in C D, heterozygosity exist A B. subgroup B, self-fertilization not possible. There moderate degree between B (Fst = 0.0744347). For genes certain regions, also ran GO enrichment KEGG Two resistance-related genes, BraA01g042910.3.5C BraA06g019360.3.5C, examined. These findings will serve as theoretical foundation for developing novel, types
