Midnight Blues Geranium Cultivar Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Geranium that exhibits unique and stable characteristics such as dark purple foliage, large blue flowers, and a vigorous growth habit, which are not met by existing Geranium cultivars like 'Midnight Reiter' and 'Hocus Pocus'.
Innovation Solution
The 'Midnight Blues' cultivar, discovered as a natural mutation and stabilized through in vitro propagation, showcases dark purple foliage, large blue flowers, and a vigorous growth habit, differing from its probable parents in leaf color and size, and flower color, with specific botanical descriptions detailing its morphology and growth traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Geranium cultivars like 'Midnight Reiter' and 'Hocus Pocus' are used, then they provide certain foliage and flower characteristics, but they fail to exhibit the unique combination of dark purple foliage, large blue flowers, and vigorous growth habit simultaneously
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific phenotypic parameters (dark purple foliage color, large blue flower size, vigorous growth rate) through in vitro propagation. This process fixed the mutant characteristics at optimal levels that do not occur naturally in the parent cultivars, creating a new parameter combination that resolves the contradiction between existing cultivar limitations and desired trait combinations.
Solution Approach 2:
The invention segments the complex trait combination into distinct observable characteristics (foliage color, flower size, growth habit) that can be independently evaluated and stabilized. By treating each trait as a separate selectable parameter during propagation, the patent successfully combined multiple desirable traits that were previously distributed across different cultivars.
2Stability of the object's composition
If in vitro propagation is used to stabilize the mutant characteristics, then the characteristics become stable and reproduce true to type, but the propagation process requires specialized laboratory conditions and techniques
Solution Approach 1:
The in vitro propagation system utilizes the plant's own cellular mechanisms for multiplication and differentiation. The cultured cells automatically undergo mitosis and develop into complete plants under controlled conditions, eliminating the need for manual intervention in each propagation step and enabling stable, true-to-type reproduction of the mutant characteristics.
Solution Approach 2:
The patent changes the physical and chemical parameters of the propagation environment (temperature, humidity, nutrient composition, light conditions) to optimize for stable characteristic reproduction. By controlling these parameters during in vitro cultivation, the mutant traits are fixed and consistently transmitted to successive generations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The 'Midnight Blues' cultivar presents a distinct and stable combination of dark purple foliage and blue flowers, offering improved growth vigor and heat tolerance, with no observed susceptibility to diseases or pests, making it a valuable addition to Geranium cultivars.
Implementation Method 1
Asexual reproduction of the new cultivar was first accomplished by in vitro propagation in Rijswijk, The Netherlands in 2009 under the direction of the Inventor. Repeated asexual reproduction has determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.
