Clematis Misty Compact Growth via Hybridization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Clematis cultivar that exhibits a compact growth habit, long flowering period, and distinctive light violet blue flower color, which are not adequately met by existing varieties like 'Carnaby', 'William Kennett', 'Lasurster', and 'Asagasumi', particularly in terms of plant height and flower color variation with environmental conditions.
Innovation Solution
The cultivar 'Misty' is developed by crossing Clematis lanuginosa 'Carnaby' with Clematis lanuginosa 'William Kennett', resulting in a compact plant with a long flowering period and light violet blue flowers, which are stable and reproduce true to type, distinguishing it from its parent varieties and commercial comparisons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing Clematis varieties like 'Carnaby' or 'William Kennett' are used, then they have good horticultural characteristics, but they produce taller plants with larger flower size variation and different flower colors (pink/dark pink) that do not meet the requirement for compact growth and light violet blue color
Solution Approach 1:
The patent applies parameter changes by crossing two parent varieties with different genetic parameters to produce offspring with modified growth parameters. The cross between 'Carnaby' and 'William Kennett' resulted in 'Misty' having reduced plant height (150 cm vs taller parents) and compact habit while maintaining other desirable traits, demonstrating change in growth parameters through hybridization
2Adaptability or versatility
If existing Clematis varieties like 'Lasurster' or 'Asagasumi' are used, then they have similar horticultural characteristics, but they produce taller plants and different flower colors (white for Asagasumi) that do not provide the distinctive light violet blue color
Solution Approach 1:
The patent utilizes parameter changes through controlled cross-breeding to achieve specific flower color parameters. The resulting variety 'Misty' exhibits light violet blue flowers (RHS 97B-97D) that are distinct from parent varieties and commercial comparisons, demonstrating successful modification of color parameters while simultaneously reducing plant height parameter
3Stability of the object's composition
If environmental conditions vary (temperature, day length, light intensity), then the phenotype of Clematis varieties may vary, but the genotype remains stable; however, existing varieties do not maintain consistent compact habit and light violet blue color across conditions
Solution Approach 1:
The patent achieves stable parameter expression by creating a new genetic combination through cross-breeding that is more robust to environmental variations. The variety 'Misty' maintains consistent compact growth habit and light violet blue flower color across varying environmental conditions, indicating stabilized growth parameters and color parameters that are less susceptible to phenotypic variation
