Hilodeamy Carnation Cultivar Compact Habit Bi-Colored Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current container carnation varieties lack attractive and stable traits such as compact growth habit, uniform flowering, and distinct flower colors, which are not consistently reproduced under varying environmental conditions.
Innovation Solution
The development of a new Carnation cultivar, 'Hilodeamy', resulting from a cross-pollination between Dianthus 'Kermit' and a proprietary selection, exhibiting a compact, upright growth habit, bi-colored semi-double flowers, and improved branching, which are stable through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current container carnation varieties are used, then they can be grown commercially, but they lack attractive and stable traits such as compact growth habit, uniform flowering, and distinct flower colors
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific phenotypic parameters (compact growth habit, bi-colored flower pattern, branching structure) that remain stable across varying environmental conditions. The cultivar 'Hilodeamy' exhibits consistent trait expression despite environmental variations, achieving reliability through optimized biological parameters.
2Adaptability or versatility
If a new Carnation cultivar is developed through cross-pollination, then unique and attractive traits are created, but the traits may not be stable under varying environmental conditions
Solution Approach 1:
The patent inverts the conventional approach by first selecting for environmental stability and trait consistency, then achieving phenotype distinctiveness. Rather than creating unique traits and hoping for stability, the breeder selected parent lines with stable inheritance patterns and verified that the offspring maintain consistent phenotypes across different growing conditions, thus ensuring reliability while achieving distinctiveness.
Solution Approach 2:
The cross-pollination between Dianthus 'Kermit' and proprietary selection A56048-01 resulted in parameter changes that produced the bi-colored flower pattern and compact growth habit. These parameter changes were selected for because they demonstrated stability across environmental variations, resolving the contradiction between distinctiveness and reliability.
3Shape
If plants are bred for compact growth habit and uniform flowering, then container performance is improved, but flower size and petal number may be reduced
Solution Approach 1:
The patent applies local quality by differentiating trait expression between different plant parts. The cultivar 'Hilodeamy' exhibits compact growth habit at the plant level while maintaining adequate flower size at the individual flower level. The bi-colored semi-double flower form concentrates visual interest in specific areas (color patterns) rather than requiring overall size increase, thus achieving compact plant habit without excessive reduction in flower dimensions.
