Clematis Evipo049 Compact Growth and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clematis plants in commercial cultivation lacked uniform and abundant near-white flowers, compact growth suitable for container culture, and improved disease resistance, which are essential qualities for nursery culture.
Innovation Solution
A new Clematis variety, 'Evipo049', was developed through controlled crossing of two non-patented seedlings, resulting in near-white flowers, vigorous and 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 near-white flowers, compact growth for container culture, and improved disease resistance
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific traits including flower color (near-white), growth habit (compact), and disease resistance. The hybridization process modifies genetic parameters to achieve the desired combination of compact size for container culture while maintaining or improving disease resistance compared to traditional varieties.
2Adaptability or versatility
If traditional clematis varieties are used, then they have natural growth patterns, but they lack compact growth suitable for container culture
Solution Approach 1:
The breeding program specifically targets and modifies the growth habit parameter to achieve compact dimensions suitable for container culture. The hybridization selects for plants with controlled vine length and bushier growth patterns, transforming the typical sprawling growth habit into a compact form that adapts well to confined container environments.
3Quantity of substance
If pure white flowers are produced, then the flowers have classic appearance, but the new variety achieves uniform and abundant near-white flowers with improved qualities
Solution Approach 1:
The patent modifies the flower production parameters to achieve both uniformity and abundance. Through selective hybridization, the breeding program increases flower quantity per plant while ensuring consistent near-white coloration and uniform bloom timing across the population, improving upon the variability found in traditional varieties.

AI summary
A new Clematis plant with a compact growth habit, profuse, near white 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.
