Clematis Evipo059 Compact Growth and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clematis plants in commercial cultivation lack uniform and abundant lavender purple flowers, compact growth suitable for container culture, and improved disease resistance.
Innovation Solution
A new clematis variety, 'Evipo059', resulting from controlled crossing between an unnamed seedling female and male pollen parent, exhibiting lavender purple flowers with a central bar, vigorous and compact growth, and enhanced disease resistance, achieved through asexual reproduction by vegetative cuttings and layering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing clematis plants are cultivated commercially, then they can be grown and maintained, but they lack uniform and abundant lavender purple flowers
Solution Approach 1:
The patent applies parameter changes by selecting specific parental varieties with desired traits and controlling the hybridization process to produce offspring with improved flower abundance and uniformity. The new variety 'Evipo059' exhibits consistent lavender purple coloration and uniform flower characteristics across multiple plants, resolving the contradiction between quantity and uniformity through controlled breeding parameter optimization.
2Adaptability or versatility
If existing clematis plants are grown for commercial cultivation, then they can be maintained, but they lack compact growth suitable for container culture
Solution Approach 1:
The patent applies local quality by selecting for specific growth habits in the new variety 'Evipo059' that are locally adapted to container culture requirements. The plant exhibits compact growth with controlled internode lengths and a growth form specifically suited for confined spaces, while maintaining overall plant health and flowering capacity, thus achieving adaptability to containers without excessive size.
3Reliability
If existing clematis plants are cultivated, then they can be grown, but they lack improved disease resistance
Solution Approach 1:
The patent applies preliminary action by incorporating disease resistance traits during the hybridization process itself, before the plants are exposed to disease pressures in commercial cultivation. The parental varieties were selected for their disease-resistant characteristics, and these traits were preliminarily established in the new variety 'Evipo059' through controlled crossing, providing preemptive protection against common clematis diseases.
4Stability of the object's composition
If asexual reproduction is performed by vegetative cuttings and layering, then true-to-type characteristics are transmitted, but the process requires controlled propagation conditions
Solution Approach 1:
The patent applies copying through asexual reproduction methods where vegetative cuttings and layering create genetically identical copies of the parent plant. This ensures that the unique characteristics of variety 'Evipo059'—including flower color, growth habit, and disease resistance—are precisely replicated in subsequent generations, maintaining stability of composition through direct copying of the genetic blueprint.

AI summary
A new Clematis plant with a compact growth habit, profuse, lavender purple flowers with a distinct purple central bar, 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.
