Carnation Double Flowering

Dianthus caryophyllus L.

Double flowering in carnation is a key ornamental trait, which is evaluated by the number of petals and is genetically controlled by the expression of AGAMOUS gene orthologs.

In the reference 336 varieties crop Carnation, where this is mentioned in the description.

The double flowering trait in carnation is classified based on petal number into single, semi-double, and double forms. In variety testing and breeding, this trait is evaluated as a quantitative characteristic with gradations from low to high petal counts, which serves as an important standard for determining the ornamental and market value of a cultivar.

Genetically, the manifestation of double flowering is linked to the expression levels of the C-class genes DcaAGa and DcaAGb, with cultivars possessing single flowers showing higher levels than double ones. In seed production, it must be considered that a high degree of double flowering often leads to reduced fertility due to the transformation of stamens into petals, which requires the application of specific breeding control methods to maintain the reproductive functions of the crop.
