Phlox Drummondii Cultivar Duephlostra Compact Red Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact Phlox plants with attractive flowers that offer distinct characteristics such as compact growth habit, freely branching, and large red-colored flowers, which are not adequately met by existing cultivars like 'Wespohopi' and 'Wespore'.
Innovation Solution
A new cultivar 'Duephlostra' of Phlox drummondii was developed through cross-pollination between Phlox drummondii 'Wespohopi' and a proprietary selection of Phlox drummondii, resulting in a compact, upright to spreading plant with freely branching and large red-colored flowers, differing from its parents in flower color and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing cultivars like 'Wespohopi' and 'Wespore' are used, then flower production is achieved, but the plants lack compact growth habit and distinctive flower color characteristics
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific phenotypic parameters including compact plant height (20-30 cm), spreading growth habit, and distinctive red flower color with specific hue and saturation characteristics. This resolves the contradiction by establishing new parameter ranges that simultaneously achieve compactness and distinctive coloration not present in parent cultivars.
Solution Approach 2:
The patent creates a composite genetic structure by cross-breeding two different Phlox drummondii cultivars ('Wespohopi' and 'Wespore') to combine desirable traits from each parent. The resulting 'Duephlostra' cultivar integrates compact growth habit from one parent with distinctive red flower coloration from the other, resolving the contradiction through genetic composition.
2Shape
If plant size is reduced to achieve compact habit, then aesthetic appeal is improved, but flowering capacity may be reduced
Solution Approach 1:
The patent applies local quality by concentrating flowering capacity in the upper portion of the compact plant structure. The plant achieves height of only 20-30 cm but compensates with dense clustering of flowers in the terminal regions and along lateral branches, creating high local flower density that maintains productivity despite reduced overall plant size.
Solution Approach 2:
The patent resolves the contradiction by transitioning from vertical growth dimension to horizontal spreading dimension. The compact plant achieves its flowering capacity through a spreading, mounding growth habit that covers greater surface area at lower height, effectively redistributing flower production across a two-dimensional plane rather than relying on vertical expansion.
3Shape
If new cultivar characteristics are introduced, then aesthetic appeal is enhanced, but stability of traits across generations may be compromised
Solution Approach 1:
The patent applies self-service through true-to-type asexual reproduction by cuttings. The new cultivar 'Duephlostra' maintains its distinctive characteristics across generations through vegetative propagation, where each cutting develops into an identical clone of the parent plant, ensuring automatic preservation of compact habit, spreading growth pattern, and red flower coloration without genetic variation.
