Helenium Balsaluemb Compact Growth Habit Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Helenium cultivars lack a compact growth habit and increased branching, which limits their horticultural appeal and adaptability in landscaping and floral arrangements.
Innovation Solution
The development of the 'Balsaluemb' cultivar of Helenium autumnale, resulting from controlled breeding, exhibits a compact and upright growth habit with medium red and yellow bi-colored inflorescences and medium green foliage, achieved through open-pollination of proprietary selections D34-1, D34-2, and D34-3, and reproduced true to type via terminal stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Helenium cultivars are used, then they have vigorous growth and large inflorescences, but they lack compact growth habit and increased branching
Solution Approach 1:
The patent applies parameter changes by selectively breeding Helenium plants to modify growth habit parameters (compactness, branching frequency, plant height) while maintaining inflorescence quality. The breeding program specifically selected for plants with increased branching and compact growth, transforming the physical parameters of the cultivar to meet horticultural demands for space-efficient landscaping options.
2Shape
If Helenium cultivars with increased branching are developed, then compact growth habit is achieved, but inflorescence size may be reduced
Solution Approach 1:
The patent applies local quality by differentiating the characteristics of different plant parts - the vegetative portion exhibits compact growth with increased branching, while the reproductive portions (inflorescences) maintain large size and vibrant bicolor characteristics. This localized optimization allows the plant to fulfill both aesthetic requirements for compact form and functional requirements for large, showy flowers.
3Adaptability or versatility
If open-pollination breeding is used, then genetic diversity is increased, but breeding precision and time to develop new cultivar is extended
Solution Approach 1:
The patent applies feedback by implementing a systematic selection process where progeny from open-pollination are evaluated against specific breeding objectives (compact growth, increased branching, bicolor inflorescences). Plants that meet the criteria are selected for further propagation, while those that do not are discarded. This feedback loop accelerates the breeding process by quickly identifying and propagating successful genetic combinations.
