Clematis Evipo071 Compact Growth and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clematis plants in commercial cultivation lacked uniform and abundant light red flowers, compact growth suitable for container culture, and improved disease resistance, which are essential qualities for nursery culture.
Innovation Solution
A new Clematis variety 'Evipo071' was developed through controlled crossing, exhibiting light red flowers, vigorous and compact growth, and enhanced disease resistance, achieved through asexual reproduction by vegetative cuttings and traditional layering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional clematis varieties are used in commercial cultivation, then they have been available for gardening use, but they lack uniform and abundant light red flowers, 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 flower color (light red), growth habit (compact), and disease resistance. The hybridization process modifies genetic parameters to achieve the desired combination of characteristics that were previously lacking in commercial clematis varieties.
2Productivity
If clematis plants are bred for vigorous growth, then they produce more flowers, but they become less suitable for container culture due to excessive size
Solution Approach 1:
The patent achieves the desired balance by changing growth parameters through controlled hybridization. The new variety 'Evipo071' exhibits vigorous flowering productivity while maintaining a compact growth habit suitable for container culture, resolving the contradiction between flower abundance and plant size.
3Reliability
If clematis plants are developed with unique flower qualities, then they meet nursery culture requirements, but they require complex hybridization programs
Solution Approach 1:
The patent applies preliminary action by conducting extensive preliminary hybridization work and selection processes to establish a stable, true-to-type variety. The complex breeding program was undertaken in advance to ensure the new variety 'Evipo071' exhibits consistent uniform light red flowers and reliable disease resistance, making it suitable for commercial nursery production.
