Calluna K6322 Cultivar Uniformity and Branch Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Calluna vulgaris cultivars lack desirable traits such as uniformity, branch thickness, and seasonal leaf color changes, which are not adequately addressed in current breeding programs.
Innovation Solution
A new cultivar, 'K6322', resulting from a controlled cross-pollination between proprietary selections K5048 and E5025, exhibits a compact, upright growth habit with thick squarish branches and light yellow leaves in autumn and winter, offering improved uniformity and distinct visual characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional Calluna vulgaris cultivars are used, then basic growth is maintained, but uniformity and branch thickness are insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in thicker branches and greater uniformity. The breeding program specifically targets parameters such as branch diameter, plant height uniformity, and branching density to overcome the limitations of existing cultivars.
2Adaptability or versatility
If existing Calluna cultivars are used, then green foliage is maintained, but seasonal color variation is lacking
Solution Approach 1:
The patent applies dynamics by introducing seasonal variability in leaf color while maintaining overall plant health and vigor. The new cultivar dynamically changes from green during the growing season to yellow in autumn and winter, providing temporal variation that enhances garden interest while maintaining reliable evergreen characteristics.
3Strength
If thicker branches are bred for, then structural strength is improved, but growth vigor may be reduced
Solution Approach 1:
The patent applies local quality by concentrating the thickened branch trait in specific locations and structures while maintaining overall plant vigor. The breeding program develops thick, squarish branches that provide structural strength where needed, while the rest of the plant maintains healthy growth rates and foliage density.
