Phlox Duephowi Cultivar Compact Habit and White Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact Phlox plants with unique and attractive flower colors, as existing cultivars lack the desired compactness and distinct flower colors, particularly in white varieties.
Innovation Solution
A new cultivar, 'Duephowi', was developed through planned breeding, resulting in a compact, upright, and freely branching Phlox plant with large white flowers, distinguished by its stable asexual reproduction and unique characteristics compared to its parent and other varieties like 'PowerPhlox White Improved'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Phlox cultivars are used, then they have larger size and more vigorous growth, but they lack compactness and have less attractive flower colors
Solution Approach 1:
The patent applies parameter changes by selectively breeding Phlox plants to modify specific growth parameters (compactness, branching density, flower size) while maintaining reproductive vigor. The cultivar 'Duephowi' exhibits altered growth parameters including reduced plant height, increased branching frequency, and enlarged flower dimensions compared to parent cultivars, achieving the desired compact form without sacrificing productivity
2Shape
If existing white Phlox varieties are used, then they provide white flower color, but they lack unique and attractive flower colors and compact form
Solution Approach 1:
The patent employs preliminary action through planned breeding programs that pre-select parent plants with desirable traits (compact growth, branching habit, flower color) before crossing. The breeder conducted systematic selection and crossing of Phlox maculata cultivars with specific characteristics, then evaluated numerous progeny to identify 'Duephowi' with the optimal combination of compact plant habit and attractive white flowers, reducing future breeding complexity
