Helenium Balsalulow 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 ornamental value and adaptability in landscaping.
Innovation Solution
A new cultivar, 'Balsalulow', is developed through controlled breeding, characterized by medium yellow inflorescences, medium green foliage, and a moderately vigorous, compact upright growth habit, achieved through open-pollination of proprietary Helenium autumnale selections and asexual reproduction.
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 parameters, specifically achieving a compact upright growth habit while increasing branching. The cultivar 'Balsalulow' exhibits altered growth parameters compared to existing cultivars, with a more compact form and increased lateral branching, demonstrating that changing physiological and morphological parameters can resolve the contradiction between growth vigor and compactness.
2Ease of manufacture
If existing Helenium cultivars are used, then they have large inflorescences, but they have wider ray florets and larger diameter inflorescences which reduce ornamental appeal
Solution Approach 1:
The patent applies local quality by modifying specific characteristics of the inflorescence while maintaining overall plant vigor. The cultivar 'Balsalulow' features narrower ray florets and smaller inflorescence diameter compared to other cultivars, creating a distinct local quality that enhances ornamental appeal. This selective modification of local characteristics (floret width and inflorescence size) resolves the contradiction by providing unique aesthetic value without compromising plant health.
