Hilrees Carnation Bi-Color Semi-Double Flower Compact Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new container carnation plants with semi-double flowers that exhibit specific traits such as compact growth, unique flower colors, and improved performance in varying environmental conditions.
Innovation Solution
A naturally occurring mutation of Dianthus caryophyllus 'Koes' has been bred to produce 'Hilrees', characterized by compact growth, dark red-purple and white bi-colored semi-double flowers, and enhanced container performance, achieved through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional carnation breeding methods are used to produce semi-double flowers, then flower form is achieved, but plant compactness and container performance are compromised
Solution Approach 1:
The patent applies parameter changes by selecting for specific genetic mutations that alter plant architecture parameters (compactness, leaf size, branching) while maintaining flower form parameters. The mutation identified in 'Hilrees' changes growth habits and plant size parameters without compromising the semi-double flower characteristic, resolving the contradiction between flower form and plant compactness.
2Area of moving object
If larger flowers are bred to improve visual impact, then flower size increases, but plant compactness and container suitability deteriorate
Solution Approach 1:
The patent applies local quality by creating a mutation that locally affects flower characteristics (larger size, bi-coloration) while maintaining or improving overall plant compactness. The 'Hilrees' cultivar demonstrates this by producing larger flowers on a compact plant framework, allowing both increased flower area and controlled plant spread suitable for containers.
3Ease of manufacture
If multiple color variations are introduced to enhance aesthetic value, then flower color diversity increases, but genetic stability and true-to-type reproduction may be compromised
Solution Approach 1:
The patent applies copying through asexual reproduction by terminal cuttings to preserve the exact genetic composition of the mutated plant. This method creates identical copies of the bi-color flower pattern and compact growth habit, ensuring genetic stability and true-to-type reproduction while maintaining the enhanced aesthetic value of the mutation.
