Peel gloss is a highly valued external quality trait that affects the market value of cucumbers, and it directly influences the purchasing psychology of consumers. Nonetheless, the candidate genes and underlying genetic mechanism for this important cucumber trait are not well understood. In this study, we successfully mapped a fruit skin gloss QTL interval to chromosome 3 (26.04-26.14 Mb) using BSA and GWAS methods. Among the eleven candidate genes in the interval, the cytochrome P450 family gene <i>CsCYP86B1</i> was identified as the candidate for control of fruit skin gloss in cucumber. The expression of <i>CsCYP86B1</i> in 0-day fruit skin was significantly lower in the low-gloss isogenMolecular breeding : new strategies in plant improvement25https://www.ebi.ac.uk/biostudies/studies/S-EPMC10248622biostudies-literatureFine mapping of a novel QTL <i>CsFSG1</i> for fruit skin gloss in cucumber (<i>Cucumis sativus</i> L.).PMC10248622Li JDu SWei ALin THuang HDu YWang HZhang LLiang BLi YLong ZYang RKong WfalseFine mapping of a novel QTL <i>CsFSG1</i> for fruit skin gloss in cucumber (<i>Cucumis sativus</i> L.).Cucumber (<i>Cucumis sativus</i> L.) is an important vegetable crop that is popular with many people.
