Dahlia HS Flame Breeding Merging Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Dahlia cultivars lack a combination of freely branching growth habit, dark-colored foliage, attractive bi-colored ray florets, and good garden performance, particularly in varying environmental conditions.
Innovation Solution
The Dahlia hybrida cultivar 'HS Flame' is developed through controlled breeding, exhibiting an upright and spreading growth habit, dark foliage, continuous flowering, daisy-type inflorescence with red and yellow bi-colored ray florets, and improved garden performance, distinguished by its unique characteristics that are stable across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Dahlia cultivars are used, then they have basic flowering capability, but they lack a combination of freely branching growth habit, dark-colored foliage, attractive bi-colored ray florets, and good garden performance
Solution Approach 1:
The patent merges multiple desirable traits (freely branching growth habit, dark-colored foliage, bi-colored ray florets, and good garden performance) into a single Dahlia cultivar through controlled cross-breeding, creating a unified plant that exhibits all these characteristics simultaneously rather than requiring separate cultivars for each trait
2Manufacturing precision
If the new Dahlia cultivar is developed through controlled breeding, then it exhibits unique characteristics including bi-colored ray florets and dark foliage, but it requires stable reproduction across generations
Solution Approach 1:
The patent performs preliminary controlled cross-breeding between specific parent selections with known characteristics, establishing the desired trait combination in the F1 generation before proceeding to asexual reproduction, ensuring that the unique characteristics are genetically established before multiplication
Solution Approach 2:
The patent uses asexual reproduction by cuttings to maintain identical genetic parameters across generations, preventing genetic variation that would occur with sexual reproduction, thereby ensuring stable reproduction of the unique traits without genetic drift
3Stability of the object's composition
If asexual reproduction by cuttings is used, then the unique features are stable and reproduced true to type, but it requires controlled environment conditions
Solution Approach 1:
The patent employs asexual reproduction by cuttings, which allows the plant to propagate itself without requiring complex pollination procedures or parental plants, simplifying the propagation process while maintaining genetic stability through identical cloning of the selected individual
