Breeding of Carnations
INQUIRYIntroductions
Carnation is a perennial plant of the Dianthus caryophyllus, native to the Mediterranean region and widely distributed in temperate regions of Europe and China. Due to its usually heavy flowers, bright colors, and fragrant scent, it has become one of the four major cut flowers with high ornamental and economic value. The carnations used in modern cut flowers have been screened for petal size and color and are virtually odorless. The completion of carnation genome sequencing has provided excellent support for carnation breeding.
With the goal of breeding for carnations, Lifeasible is working to produce carnation varieties with more diverse flower colors and shapes, shorter flowering cycles, and greater disease resistance.
What We Follow
Carnation genome information supports the improvement of ornamental traits in carnations. We can help our customers breed new carnation varieties through conventional marker-assisted breeding and various gene editing techniques.

What We Provide
Purple Carnations Breeding
Carnations do not naturally produce blue and purple petals. We can insert genes related to the biochemical pathway of delphinidin production into white carnations, down-regulating the gene's expression encoding dihydroflavonol-4-reductase by RNA interference technology, or block the expression of the gene encoding flavanone 3-hydroxylase by antisense inhibition technology to breed purple carnations of different shades.
Fragrance Carnations Breeding
Carnations do not have a strong aromatic odor. In order to improve the quality of carnations, we are able to use the principle of the synthesis of alkenes to transfer exogenous genes or alter endogenous genes to breed carnation varieties with new fragrances or enhance the original fragrance.
Optimization of Carnations Plant Morphology
The improvement of the plant morphology of carnations has been the focus of research by breeders. The plant morphology of carnations includes flowering organ morphology, flowering branch-bearing status, inflorescence type, and plant morphology. We are able to insert genes involved in regulating plant morphology into carnations to increase the number of flower buds and plugs of transgenic carnations.
Altering the Sensitivity of Carnations to Ethylene
Carnations are highly sensitive to ethylene, which induces autocatalytic ethylene production and wilting of carnation petals, affecting the longevity of vase flowers. We are able to regulate genes controlling ethylene production and ethylene sensitivity in carnations to extend the vase flower life of carnations and produce varieties with higher ornamental value.
Breeding Carnations for Disease Resistance
There are currently more than 15 viruses affecting carnation growth. The most common diseases include streak disease, caused by the bacteria genus Erwinia, and Fusarium wilt disease, caused by fungi. We are able to grow resistant plants from resistant healing tissue through tissue culture techniques.
