Echinacea Cultivar Propagation for Stable Bloom and Color Traits

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing Echinacea cultivars lack a combination of very large inflorescences, long bloom time, upright and compact habit, rose-pink ray florets with white tips, and strong stems, which are not consistently reproduced through sexual propagation.

Innovation Solution

The new Echinacea cultivar 'TNECHFT' is developed through asexual propagation (cuttings and tissue culture) to ensure consistent reproduction of its unique characteristics, including numerous medium inflorescences, extended bloom time, upright habit, and distinctive ray floret coloration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sexual propagation is used to reproduce Echinacea cultivars, then genetic diversity is maintained, but consistent reproduction of unique characteristics is not achieved

Engineering Contradiction:

Improveconsistent reproduction of characteristicsVSAvoidgenetic diversity

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies asexual propagation methods (cuttings and tissue culture) to create exact genetic copies of the parent plant, ensuring that all unique characteristics such as rose-pink ray florets with white tips, upright compact habit, and profuse inflorescences are consistently reproduced in progeny without the genetic variation introduced by sexual reproduction

Inventive Principle:

Principle #26Copying

2Productivity

If Echinacea cultivars are bred for large inflorescences and long bloom time, then flowering performance is improved, but plant habit becomes less compact and upright

Engineering Contradiction:

Improvenumber of inflorescences and bloom durationVSAvoidplant habit compactness

Core Design Contradiction:

ProductivityVSShape

Solution Approach 1:

The patent describes a cultivar that achieves a unique combination of parameters: producing over 100 inflorescences per season with extended bloom time while maintaining an upright compact habit and strong stem structure, representing an optimization of multiple growth parameters simultaneously through selective breeding

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If ray florets are bred for distinctive coloration, then aesthetic value is improved, but color consistency across propagations varies

Engineering Contradiction:

Improveaesthetic value of ray floretsVSAvoidcolor consistency

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

Through asexual propagation by cuttings and tissue culture, the patent ensures that the distinctive rose-pink ray florets with white tips are copied exactly from the parent plant, maintaining consistent coloration and patterning across all progeny without the segregation that would occur in sexual reproduction

Inventive Principle:

Principle #26Copying
