Leucanthemum Macaroon Cultivar with Double Daisy Inflorescences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Leucanthemum cultivars lack a combination of double daisy type inflorescences, yellow flower buds, and a compact habit, with existing varieties either having white young ray florets or less desirable growth habits.
Innovation Solution
A new Leucanthemum cultivar 'Macaroon' with double daisy type inflorescences, yellow flower buds, and a low, compact habit, achieved through controlled crossing and reproduced via asexual propagation, maintaining consistent characteristics across progeny.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Leucanthemum cultivars are used, then white young ray florets are produced, but the desired yellow flower buds and compact habit are not achieved
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific phenotypic traits including yellow flower buds, compact habit, and double daisy type inflorescences. The cultivar 'Macaroon' represents a deliberate modification of natural Leucanthemum parameters to achieve the desired combination of characteristics that differ from traditional white-flowered varieties.
2Stability of the object's composition
If asexual propagation is used to maintain consistent characteristics, then uniformity is achieved, but genetic diversity is reduced
Solution Approach 1:
The patent employs asexual propagation methods including division and tissue culture to create identical copies of the selected parent plant. This ensures that the unique combination of traits (yellow flower buds, compact habit, double inflorescences) is precisely replicated in all progeny, maintaining genetic uniformity and trait consistency across the cultivar population.
