Echeveria TSAECH1824 Cultivar Stability via Preliminary Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct Echeveria cultivar that exhibits unique growth and foliage characteristics, which are stable and true to type through asexual reproduction, and can thrive under varying environmental conditions while maintaining its distinct genotype.
Innovation Solution
The cultivar 'TSAECH1824' is a seedling selection from controlled pollination of Echeveria lilacina and Echeveria hybrid 'Perle von Nurnberg', characterized by compact, stemless rosettes with moderately glaucous foliage having a blue-grey and greyed-green appearance lightly suffused with lilac coloration, and conspicuously margined and tipped pink, achieved through stable asexual reproduction by rooting leaf cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new Echeveria cultivar is developed through controlled pollination, then unique growth and foliage characteristics are achieved, but stability and truth-to-type through asexual reproduction must be confirmed
Solution Approach 1:
The patent applies preliminary action by conducting multiple generations of asexual reproduction (rooting leaf cuttings) before commercialization to pre-confirm stability and truth-to-type. The cultivar underwent four generations of propagation verification to ensure the unique characteristics would be reliably inherited, eliminating the need for further stability testing during commercial production.
2Ease of manufacture
If the cultivar is selected for commercialization after confirming distinctness and stability, then commercial viability is achieved, but extensive verification time is required
Solution Approach 1:
The patent applies parameter changes by optimizing the verification process through standardized propagation protocols and selective timing of observations. The cultivar was monitored across different seasons and environmental conditions to accelerate the confirmation of stability, reducing the overall verification timeline while maintaining rigorous standards for commercial release.

AI summary
A new and distinct Echeveria plant named ‘TSAECH1824’ which is characterized by an abundance of small succulent foliage tightly held in a compact stemless rosette, moderately glaucous foliage, foliage that is colored between blue-grey and greyed-green and lightly suffused with a lilac coloration and conspicuously margined and tipped pink, and the stability of these characteristics from generation to generation.
