Cotyledon undulata Cultivar HOCO01 Stable Mutation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct and stable cultivar of Cotyledon undulata that exhibits unique characteristics such as moderate to strong branching, small near-orbicular foliage with a heavily undulated leaf margin, and moderately cupped to tubular foliage with a hastate to tubular leaf base, which are not observed under all environmental conditions.
Innovation Solution
The cultivar 'HOCO01' is derived from a spontaneous whole-plant mutation of Cotyledon undulata, characterized by its globular plant shape, small tubular foliage, and heavily undulated leaf margin, which has been stabilized through asexual reproduction via stem cuttings, maintaining these traits across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a spontaneous whole-plant mutation is selected to create a new cultivar, then unique characteristics such as moderate to strong branching and globular plant shape are achieved, but the stability of these characteristics across generations must be verified
Solution Approach 1:
The patent applies asexual reproduction through stem cuttings to create copies of the mutated plant. This allows the unique characteristics (globular shape, moderate to strong branching) to be replicated exactly without the variability introduced by sexual reproduction, thereby verifying stability across generations while maintaining the unique phenotype
2Stability of the object's composition
If the cultivar is propagated through asexual reproduction, then the unique characteristics are maintained stably, but the genetic diversity is reduced
Solution Approach 1:
The patent uses stem cuttings to produce exact copies of the mutated plant, ensuring that the unique characteristics (small near-orbicular foliage, heavily undulated leaf margin) are maintained stably across generations. This asexual reproduction method prioritizes trait stability over genetic diversity
3Measurement precision
If the plant is grown under controlled greenhouse conditions, then the unique characteristics are clearly observed and confirmed, but the adaptability to various environmental conditions is limited
Solution Approach 1:
The patent notes that the cultivar has been observed to maintain its unique characteristics across different environmental conditions including temperature, day length, and light intensity variations. The plant appears to self-regulate to maintain its phenotype without requiring controlled conditions, demonstrating environmental adaptability
