| Abstract:
Flower color is an important trait in ornamental plants. To understand the genetic basis for anthocyanin pigmentation traits in flower petals of carnation (Dianthus caryophyllus L.), we evaluated the segregation of anthocyanin contents in petals of 120 progeny of a cross between flower colors. Low anthocyanin contents (<0.5 mg/g F.W.) were the most common, and high the least common. Quantitative trait locus (QTL) analysis identified two QTLs on linkage groups 6 and 9, which accounted for 21.6% and 15.0% of the total phenotypic variance, with LOD scores of 6.33 and 4.15, respectively. | |
