Identification of QTLs and Candidate Genes Related to Flower Traits and Bolting Time in Radish (Raphanus sativus L.)

Radish flower color, bolting time, and flowering time are important traits for attracting certain pollinators affect fleshy root quality. In this study, an analysis of the anthocyanidins in radish flowers by high-performance liquid chromatography revealed that differences cyanidin content likely to be associated with variability colors (i.e., purple white petals). A quantitative trait loci (QTL) identified nine QTLs on three Raphanus sativus linkage groups. Three QTLs—qRFC1, qRBT1, qRFT1—which were consistently detected explained a high proportion observed variation (10.30% 34.57%), considered as major responsible respectively. total 16 11 candidate genes within QTL regions color bolting/flowering times, respectively, preliminarily annotated. Six (Rs018140, Rs018950, Rs019220, Rs020080, Rs020590, Rs021450) related differentially expressed parental lines. On basis nucleotide amino acid sequence diversity between lines, Rs314940, Rs315000, Rs315310, Rs315960 mediating times. This study genetic complexity traits. The may useful breeding programs also functional characterization radish.
