Kniphofia hybrida 'Amazing Fun' Phenotype Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Kniphofia hybrida that exhibits unique characteristics such as upright growth habit, moderately vigorous growth, long flowering period, and enhanced winter hardiness, which are not met by existing cultivars like 'Nancy's Red', particularly in terms of height, flower color, and flowering frequency.
Innovation Solution
The development of Kniphofia hybrida 'Amazing Fun' through cross-pollination of unnamed proprietary seedling selections, which is asexually reproduced via vegetative divisions, resulting in a plant with red-colored flower buds transitioning to orange and yellow flowers, and displaying improved winter hardiness and shorter stature compared to its parents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Kniphofia cultivars are used, then they have established growth patterns, but they lack unique characteristics such as upright growth habit, long flowering period, and enhanced winter hardiness
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific phenotypic parameters through asexual reproduction. The cultivar 'Amazing Fun' exhibits parameter changes including upright growth habit (parameter_id: 12), extended flowering period from mid-summer to early autumn (parameter_id: 15), and enhanced winter hardiness (parameter_id: 35). These parameters are maintained through true-to-type propagation, resolving the contradiction between adaptability and reliability.
2Length of moving object
If Kniphofia plants are bred for taller stature, then they have more prominent presence, but they become less winter hardy and less freely flowering
Solution Approach 1:
The patent resolves this contradiction by establishing an optimal parameter range for plant height (36-51 cm) that balances prominence with winter hardiness and flowering frequency. The upright growth habit (parameter_id: 12) provides visual prominence without excessive height, while the compact stature enhances winter survival and flowering frequency through stabilized genetic parameters achieved by asexual reproduction.
3Duration of action of moving object
If Kniphofia plants are bred for longer flowering period, then they provide extended ornamental value, but they may reduce vigor and growth rate
Solution Approach 1:
The patent resolves this contradiction by stabilizing the flowering period parameter from mid-summer to early autumn (parameter_id: 15) through true-to-type propagation, while maintaining moderately vigorous growth habit (parameter_id: 39). The balanced parameter optimization allows extended ornamental value without sacrificing growth vigor, as the cultivar achieves both objectives through stabilized phenotypic expression.
4Adaptability or versatility
If new cultivars are developed through cross-pollination, then unique characteristics emerge, but stability and true-to-type reproduction may be compromised
Solution Approach 1:
The patent applies segmentation by separating the breeding process (cross-pollination for genetic diversity) from the propagation process (asexual reproduction for stability). Cross-pollination generates unique characteristics (parameter_id: 35), while subsequent asexual reproduction through vegetative divisions stabilizes the phenotype (parameter_id: 13), achieving true-to-type reproduction of the selected cultivar.
Solution Approach 2:
The patent applies preliminary action by first conducting cross-pollination to generate genetic variation and identify desirable phenotypes, then selecting and stabilizing the chosen cultivar through asexual reproduction. This preliminary selection and stabilization process ensures that the unique characteristics achieved through cross-pollination are locked into a stable, true-to-type cultivar.
