Campanula Freya Cultivar Breeding for Compact Growth and Strong Stems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for compact, freely flowering Campanula plants with attractive flower color that can reproduce stably and consistently, as existing cultivars may vary with environmental conditions and lack desired traits like compactness and strong stems.
Innovation Solution
A new cultivar 'Freya' of Campanula glomerata was developed through planned breeding, characterized by an upright habit, freely basal branching, dark violet-colored campanulate-shaped flowers, and stronger stems, achieved through asexual reproduction by tissue culture, distinguishing it from its parent and comparable cultivars like 'Acaulis'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional Campanula cultivars are used, then they can be grown in various environments, but they lack compactness and strong stems
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in stronger stems and more compact growth habits. The new cultivar 'Freya' exhibits these improved parameters through controlled breeding programs that modify plant morphology and structural characteristics while maintaining environmental adaptability.
2Reliability
If existing Campanula varieties are used, then they can reproduce, but they do not reproduce stably and consistently
Solution Approach 1:
The patent applies preliminary action through extensive pre-breeding work and selection processes conducted before the final cultivar is established. Multiple generations of controlled breeding and rigorous selection were performed to ensure the new cultivar 'Freya' possesses stable and consistent reproductive characteristics and flowering performance.
3Volume of moving object
If compact growth habit is selected, then plant size is reduced, but flowering freedom may be compromised
Solution Approach 1:
The patent applies local quality by creating a plant with heterogeneous characteristics - the overall plant structure is compact and controlled, while the flowering portions exhibit high productivity and freedom. The new cultivar 'Freya' demonstrates this by having a compact growth habit combined with multiple flowering stems and abundant flower production, achieving both size control and flowering freedom simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The new cultivar 'Freya' exhibits stable and consistent traits, including compactness, strong stems, and increased flowering, making it suitable for various environments and commercial production, with improved tolerance to temperature and light variations.
Implementation Method 1
Asexual reproduction of the new Campanula plant by tissue culture in The Netherlands, since October, 2008, has shown that the unique features of this new Campanula plant are stable and reproduced true to type in successive generations.
