Clematis Evipo081 Compact Growth and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clematis plants in commercial cultivation lacked uniform and abundant red flowers, vigorous and compact growth suitable for container culture, and improved disease resistance, which are essential qualities for nursery culture.
Innovation Solution
A new Clematis variety, 'Evipo081', was developed through controlled crossing of un-named seedlings, exhibiting Red Group 53A tepals, compact growth, and enhanced disease resistance, achieved by asexual reproduction methods like vegetative cuttings and layering, demonstrating stability of characteristics across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Clematis cultivars are used for commercial cultivation, then they have been available for gardening purposes, but they lack uniform and abundant red flowers, vigorous and compact growth suitable for container culture, and improved disease resistance
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific traits including compact growth habit, uniform red flower color (Red Group 53A), and disease resistance. The new variety 'Evipo081' exhibits modified parameters compared to traditional cultivars: compact size suitable for containers, uniform tepal coloration, and enhanced resistance to common Clematis diseases, thereby resolving the contradiction between reliability and adaptability
Solution Approach 2:
The new Clematis variety 'Evipo081' achieves multi-functionality by simultaneously providing: (1) uniform and abundant red flowers for aesthetic purposes, (2) compact vigorous growth for container culture adaptability, and (3) improved disease resistance for reliable cultivation. This single variety satisfies multiple previously unmet requirements, making it universally suitable for various gardening applications
2Productivity
If Clematis plants are bred for vigorous growth, then they produce more flowers, but they may become too large for container culture
Solution Approach 1:
The patent resolves this contradiction by changing the growth parameter from vigorous sprawling growth to compact vigorous growth. The new variety 'Evipo081' maintains high flower abundance and productivity while constraining the volume and spread of the plant, making it suitable for container culture. The plant produces uniform red flowers abundantly within a compact form, achieving both productivity and size control
3Manufacturing precision
If Clematis plants are bred for uniform red flowers, then aesthetic quality improves, but other qualities such as disease resistance and growth habit may be compromised
Solution Approach 1:
The patent achieves multi-functionality by breeding a variety that simultaneously exhibits: (1) uniform red flowers (Red Group 53A) for aesthetic quality, (2) compact vigorous growth for container suitability, and (3) improved disease resistance for reliability. The new variety 'Evipo081' does not compromise any single quality but rather integrates multiple desirable traits that were previously lacking in commercial cultivars
