Clematis Evipo072 Compact Growth and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clematis plants in commercial cultivation lacked uniform and abundant pink flowers, compact growth suitable for container culture, and improved disease resistance.
Innovation Solution
A new Clematis variety 'Evipo072' was developed through controlled crossing, characterized by pink 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 cultivars are used for commercial cultivation, then they have been available for gardening purposes, but they lack uniform and abundant pink 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 compact growth habit, uniform pink flower coloration, and enhanced disease resistance. The hybridization process modifies genetic parameters to achieve a combination of qualities that were previously lacking in commercial clematis cultivars, particularly creating a variety suitable for container culture while maintaining robust health characteristics
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 applies local quality by creating a variety with differentiated growth characteristics - compact overall size suitable for containers while maintaining vigorous flowering capability. The hybridization produces a plant that concentrates its energy into producing abundant flowers within a limited spatial footprint, rather than expanding overall plant volume
3Manufacturing precision
If clematis plants are bred for uniform flower color, then they meet commercial standards, but they lack the disease resistance needed for reliable cultivation
Solution Approach 1:
The patent applies merging by combining multiple desirable traits through hybridization - uniform pink flower coloration, compact growth habit, and enhanced disease resistance. The controlled crossing between selected parent plants integrates these previously separate characteristics into a single variety that exhibits all three qualities simultaneously

AI summary
A new Clematis plant with a compact growth habit, profuse, pink flowers, and continuous summer flowering. The variety successfully propagates from softwood cuttings and is suitable for cultivation in 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.
