Clematis WIT141205 Cultivar Development via Asexual Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Clematis koreana var. carunculosa that exhibits unique and stable characteristics such as nodding, semi-double flowers with staminode centers, light yellow flowers tinted brownish purple, and a long blooming habit, which are not found in existing cultivars like 'Love Child' and 'Lemon Bells'.
Innovation Solution
The cultivar 'WIT141205' is developed through asexual propagation by softwood stem cuttings, showcasing nodding, semi-double flowers with light yellow and brownish purple tinted tepals, a long blooming habit from spring to summer, and cold hardiness to at least U.S.D.A. Zone 5, distinguishing it from its parent 'Love Child' and similar cultivars like 'Lemon Bells'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If asexual propagation by softwood stem cuttings is used, then stable and true-to-type reproduction is achieved, but propagation time and complexity increase
Solution Approach 1:
The patent performs preliminary selection of the most vigorous and representative plant from the seedling population before propagation. This ensures that the selected parent plant already exhibits the desired stable characteristics, so that propagation by cuttings will true-to-type reproduce these traits without requiring additional selection steps during propagation.
2Ease of manufacture
If unique flower characteristics are developed, then cultivar distinctiveness is improved, but breeding complexity increases
Solution Approach 1:
The patent creates a stable copy of the unique flower characteristics by propagating the selected plant asexually through softwood stem cuttings. This copying process preserves the distinctive semi-double flower form, staminode centers, and color patterns exactly as they appear in the parent plant, ensuring cultivar distinctiveness is maintained across generations without requiring complex breeding programs.
