Hibiscus TAHI12 Cultivar Propagation and Trait Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Hibiscus that combines specific traits such as an upright plant habit, large light pink flowers with dark purple-red veins and eye-zone, and green foliage suffused with dark purple, which are stable and true to type through asexual propagation.
Innovation Solution
The development of Hibiscus×moscheutos 'TAHI12' through a cross between Hibiscus 'Summer Storm' and Hibiscus×moscheutos 'Griotte', utilizing softwood stem cuttings and tissue culture for asexual propagation to reproduce the desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If asexual propagation by softwood stem cuttings and tissue culture is used, then the characteristics of the new cultivar are stable and reproduced true to type, but the propagation process requires specific technical knowledge and resources
Solution Approach 1:
The patent employs asexual propagation methods (softwood stem cuttings and tissue culture) to create genetic copies of the selected parent plant, ensuring that the offspring reproduce the desired traits true to type without the variability introduced by sexual reproduction. This copying process maintains the stability of cultivar characteristics while requiring controlled propagation techniques.
2Area of moving object
If large flowers up to 25 cm in diameter are produced, then the aesthetic appeal and visibility of the plant are enhanced, but the energy and resource requirements for flower development increase
Solution Approach 1:
The patent utilizes parameter changes in the breeding process, selecting and propagating plants with specific genetic parameters that enable large flower size (up to 25 cm diameter) while maintaining optimal energy efficiency. The controlled asexual propagation ensures that these parameter changes are stabilized and reproduced consistently across generations.
3Shape
If the plant habit is upright and well-branched, then the plant structure is improved for landscape and container use, but the branching development requires specific genetic control and environmental conditions
Solution Approach 1:
The patent applies local quality principles by selecting and propagating plants with specific localized characteristics (upright habit and well-branched structure) while maintaining overall genetic stability through asexual propagation. This allows the plant to exhibit consistent structural qualities across different environments, balancing form with environmental adaptability.
