Seedless Chilopsis Cultivar with Dense Foliage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Chilopsis linearis cultivars lack early and freely flowering varieties with attractive flower coloration, and they often produce fruits and seeds, which may not be desirable in all horticultural applications.
Innovation Solution
A new cultivar, 'MSWNLopur', resulting from a planned breeding program, exhibits an upright to somewhat outward plant habit, moderately vigorous growth, numerous small leaves, dark purple-colored flowers that do not produce fruits or seeds, and is propagated via cuttings, distinguishing it from other Chilopsis linearis cultivars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Chilopsis linearis cultivars are used, then they typically produce fruits and seeds, but this is not desirable in all horticultural applications
Solution Approach 1:
The patent extracts and eliminates the seed production function from the Chilopsis linearis plant through selective breeding. The cultivar 'MSWNLopur' was specifically bred to produce dark purple flowers that do not develop into fruits or seeds, removing this characteristic from the plant variety while maintaining other desirable traits.
2Productivity
If new Chilopsis cultivars are developed through breeding programs, then early and freely flowering varieties with attractive coloration can be created, but the breeding process requires significant time and resources
Solution Approach 1:
The patent applies preliminary action through a structured breeding program that began in 1998. The inventor performed preliminary crosses between Chilopsis linearis 'Lucretia Hamilton' and Chilopsis linearis 'Art's Seedless' to pre-establish genetic lines with desired traits before selecting and propagating the final cultivar 'MSWNLopur' in 2004, thereby systematically working toward the target characteristics over time.
3Ease of manufacture
If Chilopsis plants are bred for dense foliage and full growth habit, then ornamental value is improved, but the plant structure becomes more complex
Solution Approach 1:
The patent applies local quality by enhancing specific parts of the plant for ornamental purposes. The cultivar 'MSWNLopur' exhibits dense foliage, full rounded growth habit, and particularly striking dark purple flowers, while maintaining a manageable overall structure. The breeding focused on improving local characteristics (flower color, foliage density) rather than fundamentally changing the entire plant architecture.
