Cotoneaster Lemon Funky Cultivar Color Mutation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of distinct cultivars in Cotoneaster dammeri that exhibit unique characteristics such as yellow-green foliage, grey-purple stems, and green-white flowers, which are not found in existing varieties.
Innovation Solution
The new cultivar 'Lemon Funky' of Cotoneaster dammeri, discovered as a branch mutation, exhibits these distinct traits, including yellow and maturing to yellow-green young foliage, grey-purple stems, and green-white flowers, and is propagated through terminal cuttings, maintaining stability in successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional Cotoneaster dammeri cultivars are used, then they exhibit green foliage and grey-green stems, but they lack visual distinctiveness and unique characteristics
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a mutant plant with altered foliage color parameters (yellow-green instead of green) and stem color parameters (grey-purple instead of grey-green). This changes the visual characteristics of the cultivar to achieve greater distinctiveness while maintaining the species' hardy nature and adaptability.
2Ease of manufacture
If new mutant characteristics are selected, then visual distinctiveness is improved, but stability across generations must be ensured
Solution Approach 1:
The patent uses terminal cuttings (a form of asexual propagation) to reproduce the mutant plant. This method ensures that the unique characteristics are cloned exactly in successive generations, maintaining stability and trait consistency without requiring complex breeding programs.
3Adaptability or versatility
If distinct color variations are developed, then landscaping versatility is improved, but disease and pest resistance must be maintained
Solution Approach 1:
The patent maintains the overall hardy constitution and disease resistance of the parent Cotoneaster dammeri species while introducing localized color variations in foliage and stems. The mutant plant retains the species' inherent reliability regarding disease and pest resistance despite the altered visual characteristics.
