Abstract

<abstract abstract-type="main" id="pbr12286-abs-0001"> <title>Abstract</title> <p>Variegated leaf colour is an important agronomic trait that affects the market value of ornamental kale (<italic>Brassica oleracea</italic> L. var. <italic>acephala</italic>). The red leaf phenotype in kale is due to anthocyanin accumulation. To investigate the pattern of inheritance of this trait, we constructed an F₂ population by crossing 'Y005‐15', a double haploid with red leaves, with a white‐leaved double haploid, 'Y011‐13‐38', followed by self‐pollination. An F₂ population consisting of 4284 individuals was used to study the inheritance of this trait, which showed that the character was controlled by a dominate gene. All of the 1050 white leaf trait plants in the F₂ were used for mapping and developing markers linked to <italic>Re</italic> gene. Results showed that <italic>Re</italic> was mapped to a locus on linkage group C09 of <italic>Brassica oleracea</italic>, and the locus was mapped between six SSR markers (C9Z1, C9Z16‐1, C9Z90, C9Z94, C9Z96 and C9Z99), with a genetic distance of 6.7, 1.0, 0.3, 2.0, 2.1 and 0.4 cM from <italic>Re</italic> gene, respectively. These results may facilitate marker‐assisted selection of the red leaf trait in kale breeding as well as map‐based cloning of the red leaf trait gene.</p> </abstract>
