Rosmarinus Wilma's Gold Cultivar Solid Gold Foliage Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Rosmarinus officinalis with unique and stable characteristics, such as solid gold-colored foliage, that distinguishes it from existing varieties and is adaptable across varying environmental conditions.
Innovation Solution
The cultivar 'Wilma's Gold' exhibits stable and true-to-type unique features, including solid gold-colored foliage, a trailing plant form, and lighter-colored flowers, which differentiate it from parent and similar varieties like 'Blue Rain', 'Gold Dust', and 'Golden Rain', with propagation methods ensuring consistent production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a new Rosmarinus cultivar with solid gold-colored foliage is developed, then ornamental value and distinctiveness are improved, but stability of characteristics across environmental conditions may be compromised
Solution Approach 1:
The patent describes a whole plant mutation that changed the foliage color parameter from green to solid gold. This natural genetic parameter change created a stable yet visually distinct cultivar that maintains its golden color across different environmental conditions, resolving the contradiction between ornamental value and stability.
2Stability of the object's composition
If vegetative propagation is used to reproduce the cultivar, then genetic stability is improved, but time and resources for propagation are increased
Solution Approach 1:
The patent documents that the cultivar was propagated through vegetative cuttings starting in 2006, with multiple generations reproduced since then. This preliminary establishment of propagation protocols and selection of stable genotypes allows for efficient reproduction while maintaining genetic stability, reducing the time and resources needed for future propagation cycles.
