Echinacea Noecseven Cultivar Compact Habit and Flowering Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Echinacea cultivars lack compact, freely branching, and highly flowering varieties with unique and attractive ray floret coloration, which limits their aesthetic and horticultural appeal.
Innovation Solution
A new cultivar, 'Noecseven', resulting from a planned breeding program combining Echinacea angustifolia x Echinacea purpurea, exhibiting a compact upright habit, moderately vigorous growth, strong flowering stems, and purplish red-colored ray florets, achieved through in vitro meristem culture and selection from 'Sensation Pink', offering improved compactness, branching, and flowering density compared to parent varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Echinacea cultivars are used, then they have larger inflorescences and less compact growth, but they lack the desired compactness, free branching, and high flowering density
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic traits through in vitro meristem culture and repeated asexual reproduction. The cultivar 'Noecseven' exhibits altered growth parameters including compact habit, free branching, and high flowering density compared to parent cultivars, achieving simultaneous improvement in plant shape and flowering productivity through controlled propagation methods
2Ease of operation
If Echinacea plants are bred for compactness and free branching, then garden performance improves, but maintaining stable characteristics across generations becomes challenging
Solution Approach 1:
The patent applies preliminary action by performing in vitro meristem culture and establishing stable genetic lines before commercial propagation. The cultivar characteristics were stabilized through repeated asexual reproduction in controlled environments prior to distribution, ensuring that garden performance traits remain consistent across generations without requiring further breeding intervention
Solution Approach 2:
The patent applies copying through asexual reproduction by in vitro meristem culture, which creates genetically identical copies of the selected plant. This propagation method ensures that the compact habit, free branching, and other desirable traits are replicated precisely in successive generations, maintaining characteristic stability while enabling commercial production
3Shape
If new cultivars with unique ray floret coloration are developed, then aesthetic appeal increases, but breeding time and resource investment increase
Solution Approach 1:
The patent applies taking out by extracting and isolating the specific mutation event that produced the unique purplish red ray floret coloration from the parent cultivar 'Sensation Pink'. Through in vitro meristem culture, the desired color trait was separated and stabilized in a distinct cultivar line, allowing the unique coloration to be propagated without requiring continued breeding investment
