Dianthus Coral Reef Compact Habit and Salmon Pink Blooms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current carnation cultivars lack a compact, perennial variety with bright salmon pink flowers and grey-green foliage suitable for pots and containers, exhibiting stable traits through asexual reproduction.
Innovation Solution
Development of the Dianthus 'CORAL REEF' cultivar, a complex hybrid resulting from open pollination between Dianthus 'Devon Flavia' and an unidentified Dianthus hybrid, characterized by a compact habit, profuse blooming, and specific flower and foliage features, achieved through vegetative cuttings and stable asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a compact habit is achieved in carnation cultivars, then the plant becomes suitable for pots and containers, but the blooming profusion and flower size may be reduced
Solution Approach 1:
The patent achieves a compact habit while maintaining profuse blooming by changing the growth parameters of the carnation cultivar through selective breeding. The cultivar 'CORAL REEF' exhibits a compact mound-shaped growth habit with controlled height (20-30 cm) and width (30-40 cm), while simultaneously producing abundant flowers throughout the growing season. This resolves the contradiction by optimizing plant architecture parameters without sacrificing reproductive output.
2Stability of the object's composition
If stable traits are achieved through asexual reproduction, then the cultivar characteristics remain consistent across generations, but genetic diversity and adaptability may be reduced
Solution Approach 1:
The patent employs vegetative propagation through cuttings to reproduce the cultivar 'CORAL REEF' asexually, creating genetically identical copies that preserve the desired compact habit, flower color, and blooming characteristics across generations. This copying mechanism ensures trait stability and consistency in commercial production while the initial hybrid breeding event captured the necessary genetic diversity to achieve the target phenotype.
3Ease of manufacture
If bright salmon pink flowers with pale edges are selected, then the aesthetic appeal is enhanced, but the natural occurrence of such specific color patterns may be rare
Solution Approach 1:
The patent achieves the distinctive bright salmon pink flowers with pale edges through local quality differentiation in the flower petals. The cultivar exhibits specific color zoning where the petal centers are bright salmon pink and the margins are pale pink, creating an aesthetically appealing two-toned effect. This local quality variation was selected and stabilized through breeding, making the complex color pattern a consistent characteristic of the cultivar.
