Echinacea hybrida Cultivar Apecssired Compact Habit and Red Florets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Echinacea hybrida cultivars lack a combination of compact, vigorous, and freely branching growth habits with unique and attractive ray floret coloration, as well as uniformity in environmental conditions.
Innovation Solution
The development of a new Echinacea hybrida cultivar 'Apecssired' through planned breeding, characterized by a broadly upright and compact plant habit, moderately vigorous growth, freely branching stems, and red-colored ray florets, achieved through open-pollination and stabilized via tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Echinacea hybrida cultivars are grown, then they produce flowers, but they lack a combination of compact, vigorous, and freely branching growth habits with uniformity in environmental conditions
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific growth parameters (compact habit, vigorous growth, free branching) through controlled breeding and tissue culture propagation. This ensures uniform expression of desired traits across different environmental conditions while maintaining genetic stability.
Solution Approach 2:
The patent uses tissue culture to create exact genetic copies of the selected plant, ensuring that the uniformity of growth habits and environmental adaptability are reproduced true-to-type in successive generations, eliminating variability present in open-pollinated progeny.
2Ease of manufacture
If existing Echinacea hybrida cultivars are grown, then they produce inflorescences, but they lack unique and attractive ray floret coloration
Solution Approach 1:
The patent changes the color parameter of ray florets from conventional colors to unique red/orangish-red coloration through selective breeding, and stabilizes this color trait through tissue culture propagation to ensure uniform color expression.
3Adaptability or versatility
If open-pollination breeding is used, then genetic diversity is achieved, but uniformity of traits in progeny is reduced
Solution Approach 1:
The patent performs preliminary selection of superior individuals with desired traits (compact habit, vigorous growth, free branching, red ray florets) from open-pollinated progeny before propagation. This preliminary selection ensures that only plants with uniform and stable traits are propagated through tissue culture, combining genetic diversity with trait uniformity.
Solution Approach 2:
The patent uses tissue culture to create genetically identical copies of the selected superior plant, ensuring that the uniformity of selected traits is maintained in all propagated plants, eliminating the variability inherent in open-pollinated seed production.
