Miniature Rose WEKtebodoko Large Flower Size Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rose cultivars lack a variety with unique painted pink and white flower coloration, excellent color stability, and large flower size suitable for outdoor garden decoration, while also being resistant to powdery mildew and rust.
Innovation Solution
The new Rosa hybrida variety 'WEKtebodoko' features painted pink and white flower coloration, excellent color stability, large flower size, and a bushy rounded moderately spreading growing habit, which can be asexually propagated through budding and grafting, displaying resistance to powdery mildew and rust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If rose cultivars are bred for large flower size, then flower diameter increases, but the plant height and spread become significantly larger
Solution Approach 1:
The patent applies local quality by concentrating genetic traits to produce large flowers (4.8-6.5 cm diameter) in a specific location (the flower head) while maintaining the overall plant size within miniature rose constraints (92-120 cm height). This is achieved through selective breeding that targets flower size genes independently from plant size genes, allowing the flower to be locally enlarged without proportionally increasing the entire plant structure.
2Ease of manufacture
If rose cultivars are bred for unique painted pink and white coloration, then color variety increases, but color stability throughout flower life decreases
Solution Approach 1:
The patent applies parameter changes by carefully selecting and combining specific color genes from parent cultivars to create a painted pink and white coloration pattern that remains stable throughout the flower's lifespan. The breeding process optimizes the expression parameters of color genes (pigment type, concentration, distribution) to achieve both variety (painted effect) and stability (consistent color throughout flower life), resolving the contradiction between color variety and color stability.
3Reliability
If rose cultivars are bred for disease resistance, then resistance to powdery mildew and rust increases, but genetic diversity decreases
Solution Approach 1:
The patent applies composite materials by creating a composite genotype that combines disease resistance genes from resistant parent cultivars with genes for unique coloration and miniature size. The breeding process integrates multiple genetic components (disease resistance, color pattern, size control) into a single unified cultivar that exhibits all desired traits simultaneously, maintaining genetic diversity through the combination of different parental contributions while achieving reliable disease resistance.
