Dianthus DCAPE04-0 Spontaneous Mutation for Color Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct Dianthus cultivar that exhibits specific horticultural characteristics such as floriferous plants, suitable for both garden and container uses, with unique flower colors and continuous flowering capabilities, while being hardy and stable across varying environmental conditions.
Innovation Solution
The cultivar 'DCAPE04-0' is a spontaneous mutation of Dianthus hybrida, characterized by pastel pink to red-purple flowers with a white base, semi-double blooms, and hardiness to USDA zone 3, achieved through asexual reproduction by vegetative cuttings, maintaining stability across environmental variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a new Dianthus cultivar is developed with unique horticultural characteristics, then the variety's distinctiveness and commercial value are improved, but the stability and consistency of these characteristics across generations must be maintained
Solution Approach 1:
The patent uses asexual reproduction through vegetative cuttings to create identical genetic copies of the parent plant. This copying method ensures that the unique flower color characteristics (Pastel pink to red-purple with white base) are precisely replicated across generations without genetic variation, maintaining both distinctiveness and stability.
2Duration of action of moving object
If the cultivar is bred for continuous flowering from Spring through Fall, then the duration of action is improved, but the plant's ability to maintain hardiness across USDA zones must be preserved
Solution Approach 1:
The patent describes a plant that has undergone spontaneous mutation, resulting in changed physiological parameters including extended flowering duration (Spring through Fall) while maintaining the genetic parameters for hardiness (USDA zone 3). The mutation altered the flowering cycle parameters without compromising the cold tolerance parameters.
3Quantity of substance
If the plant is selected for floriferous characteristics with multiple petals, then the quantity of flowers and petals is improved, but the complexity of the flower structure increases
Solution Approach 1:
The patent describes a semi-double flower form with 14-20 petals, which is more than a single flower but less than a fully double flower. This partial multiplication of petals provides enhanced floriferous characteristics while avoiding the excessive complexity of fully double flowers, achieving a balance between quantity and manageability.
4Manufacturing precision
If the cultivar is discovered as a spontaneous mutation, then the uniqueness and distinctiveness are improved, but the predictability of breeding and reproduction becomes more difficult
Solution Approach 1:
While the origin was a spontaneous mutation (unpredictable), the patent resolves the breeding predictability issue by using asexual reproduction through vegetative cuttings. This copying method makes the propagation process predictable and reliable, as each cutting is a genetic clone of the parent, eliminating the uncertainties of sexual reproduction while preserving the unique mutated characteristics.
