What is QTL mapping and transcriptome analysis identify novel QTLs and candidate genes in Brassica villosa for quantitative resistance against Sclerotinia sclerotiorum about?
## Key message **Novel QTLs and candidate genes for Sclerotinia-resistance were identified in** **__B. villosa__** **, a wild Brassica species, which represents a new genetic source for improving oilseed rape resistance to SSR.** ## Abstract Sclerotinia stem rot (SSR), caused by __Sclerotinia sclerotiorum,__ is one of the most destructive diseases in oilseed rape growing regions. To date, there is no effective genetic resistance against __S. sclerotiorum__ in the __B. napus__ germplasm and knowledge of the molecular plant–fungal interaction is also limited. To identify new resistance resources, we screened a set of wild Brassica species and identified __B. villosa__ (BRA1896) with a high level of Sclerotinia-resistance. Two segregating __F__~2~ populations for Sclerotinia-resistance, generated by interspecific crosses between the resistant __B. villosa__ (BRA1896) and the wild susceptible __B. oleracea__ (BRA1909) were assessed for Sclerotinia-resistance. Genetic mapping using a 15-k Illumina Infinium SNP-array resulted in a high-density genetic map containing 1,118 SNP markers and spanning a total genetic length of 792.2 cM. QTL analysis revealed seven QTLs explaining 3.8% to 16.
