Variety traits
Dianthus L.
Double-floweredness in carnations is a morphological trait representing the degree of flower fullness with petals replacing stamens and the pistil. It is a key ornamental characteristic that determines the market class of products and is taken into account in breeding and variety testing.
In the reference 163 varieties crop Carnation, where this is mentioned in the description.
In carnations, single, semi-double, and double flower forms are distinguished, where single flowers have a standard number of petals, while double flowers possess a significantly higher number, which increases inflorescence density. In breeding, the trait is evaluated according to DUS-test methodologies in accordance with UPOV guidelines, where the flower type or the degree of expression is recorded on a scale from weak to strong.
The trait influences seed production, as excessive double-floweredness can reduce plant fertility, requiring the use of male sterility selection methods to control progeny quality. In agronomy, double-floweredness indirectly affects cultivation through increased requirements for supporting the development of large and heavy flowers.
