Clematis Breeding for Larger Flowers and Durable Seed Heads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Clematis cultivars with larger flowers, unique flower characteristics, and distinct traits that differentiate them from existing varieties, particularly in terms of flower size, shape, and durability of seed heads.
Innovation Solution
The development of the Clematis cultivar 'Violet Lampion', resulting from controlled breeding, which features larger, medium purple, drooping flowers with two flowering seasons, irregularly toothed leaves, and durable fluffy seed heads, achieved through asexual reproduction by softwood cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional Clematis alpina varieties are used, then they are available on the market, but their flowers are small and seed heads are non-ornamental
Solution Approach 1:
The patent merges traits from two different parent plants (Clematis faurei x sibirica x macropetala 'Joe Zary' and Clematis alpina 'Purple Spider') through controlled cross-breeding to produce offspring with enlarged flowers and ornamental seed heads, combining desirable characteristics from both parents
2Adaptability or versatility
If Clematis varieties with unique characteristics are developed, then they differentiate from existing varieties, but they require controlled breeding programs
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-breeding between selected parent plants with known desirable traits before mass propagation, ensuring that unique characteristics are established in the genotype before commercial production begins
3Stability of the object's composition
If asexual reproduction is used to propagate the cultivar, then distinctive characteristics are retained, but multiple propagations are required
Solution Approach 1:
The patent utilizes softwood cutting propagation, which changes the physiological state of the plant material to enable rapid asexual reproduction while maintaining genetic fidelity to the parent plant's distinctive characteristics
