Callicarpa Kolmsqueen Compact Habit Large White Berries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Callicarpa bodinieri with large white berries suitable for garden use, as existing varieties either have less compact plant habits or smaller berry sizes.
Innovation Solution
The development of the 'Kolmsqueen' cultivar, which features an abundance of large white berries borne on round clusters and a compact plant habit, achieved through a breeding program and stabilized via asexual propagation by stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Callicarpa varieties are used, then they have established plant habits, but they either have less compact plant habits or smaller berry sizes
Solution Approach 1:
The breeding program modified genetic parameters through controlled pollination to achieve a new combination of traits: compact plant habit (parameter change in growth architecture) and large berry size (parameter change in fruit dimensions). The resulting 'Kolmsqueen' cultivar exhibits berries 1.0-1.5 cm in diameter and a compact upright habit, representing simultaneous optimization of both parameters through genetic parameter changes.
2Quantity of substance
If existing Callicarpa varieties are used, then they have established characteristics, but they lack the combination of large white berries and compact growth
Solution Approach 1:
The invention applies local quality by developing a cultivar with specific localized characteristics: large white berries (1.0-1.5 cm diameter) concentrated in rounded clusters, combined with a compact upright plant habit. This localized optimization of fruit size and plant architecture makes the cultivar particularly suitable for garden and landscape applications where space efficiency and visual impact are important.
3Adaptability or versatility
If open pollination breeding is used, then genetic diversity is achieved, but stability of characteristics requires asexual propagation
Solution Approach 1:
The breeding program performed preliminary action through open pollination to generate genetic diversity and identify promising variants. Once a plant with desirable traits (large white berries, compact habit) was identified, asexual propagation by stem cuttings was immediately implemented to preserve and stabilize these characteristics. This two-stage approach—first generating diversity through sexual reproduction, then stabilizing through asexual propagation—ensures both adaptability and characteristic consistency.
