Kniphofia Echo Yello Cultivar Breeding for Re-blooming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Kniphofia uvaria with unique flower colors combined with a re-blooming habit that is not currently met by existing cultivars, which often have less floriferous or later blooming habits and different flower colors.
Innovation Solution
The development of 'Echo Yello', a new cultivar of Kniphofia uvaria with clear citron yellow flowers, a floriferous and early blooming habit, and re-blooming characteristics, derived from a controlled breeding program, which exhibits stable traits through asexual propagation and in vitro methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Kniphofia cultivars are used, then they have established flower colors and growth habits, but they lack unique flower colors combined with re-blooming habit
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific phenotypic parameters: flower color (clear citron yellow), blooming timing (early spring to fall), and flowering intensity (floriferous). This systematic selection of parameter combinations creates a cultivar with unique characteristics not present in existing cultivars.
2Speed
If Kniphofia cultivars with early blooming are selected, then blooming time is improved, but flower color variety is limited
Solution Approach 1:
The patent merges multiple desirable traits that were previously separate: early blooming timing, clear citron yellow flower color, and re-blooming habit. By combining these parameters in a single cultivar, the invention overcomes the limitation of having to choose between blooming time and color variety.
3Stability of the object's composition
If existing cultivars are propagated, then propagation stability is maintained, but unique color and re-blooming traits are not reproduced
Solution Approach 1:
The patent uses asexual propagation methods (division and in vitro propagation) to create exact copies of the selected plant. This ensures that the unique combination of clear citron yellow flowers and re-blooming habit is faithfully reproduced in successive generations, maintaining both stability and uniqueness of traits.
