Clematis Evipo048 Compact Growth and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clematis plants in commercial cultivation lacked uniform and abundant mauve flowers, compact and vigorous growth suitable for container culture, and improved disease resistance.
Innovation Solution
A new Clematis variety 'Evipo048' was developed through controlled crossing, characterized by violet flowers, compact growth, and enhanced disease resistance, achieved through asexual reproduction by vegetative cuttings and layering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional clematis varieties are used for commercial cultivation, then they have been available for gardening use, but they lack uniform and abundant mauve flowers, compact growth suitable for container culture, and improved disease resistance
Solution Approach 1:
The patent applies parameter changes by creating a new clematis variety with modified genetic parameters through controlled hybridization. The cross between specific parent plants (Clematis 'Evipo023' and another clematis variety) produces offspring with altered growth parameters including compact habit, uniform flower production, and enhanced disease resistance, making the plant adaptable to container culture while maintaining reliability
2Productivity
If clematis plants are bred for vigorous growth, then they produce abundant flowers, but they become less suitable for container culture due to excessive size
Solution Approach 1:
The patent applies local quality by creating a clematis variety with differentiated growth characteristics in different parts of the plant. The variety exhibits compact overall plant size and internode spacing while maintaining abundant flower production capacity. This localized optimization allows the plant to fit container constraints while preserving high floral productivity through controlled hybridization that selects for these specific local traits
3Reliability
If clematis varieties are selected for disease resistance, then they survive better in cultivation, but they may lack uniform and abundant flowering characteristics
Solution Approach 1:
The patent applies merging by combining multiple desirable traits from different parent plants into a single unified variety. Through controlled hybridization between Clematis 'Evipo023' and another clematis variety, the offspring integrates disease resistance from one parent with uniform mauve flower production and compact growth from the other parent, achieving a combination of reliability and manufacturing precision that neither parent possessed alone

AI summary
A new Clematis plant with a compact growth habit, profuse, mauve flowers, and continuous summer flowering. The variety successfully propagates from softwood cuttings and is suitable for cultivation commercial nursery culture. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation from vegetative cuttings.
