Phlox Appofamcer Compact Habit Large Flower Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact and vigorous Phlox plants with numerous large flowers that can thrive under various environmental conditions and cultural practices, while maintaining distinct characteristics such as flower color and compact growth habit.
Innovation Solution
A new cultivar of Phlox paniculata, 'Appofamcer', was developed through controlled breeding, exhibiting a broadly upright and compact plant habit, numerous large red-purple flowers, long flowering period, and good garden performance, distinguished from other Phlox varieties by its unique flower color and size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional Phlox breeding methods are used, then flower size and number can be increased, but plant compactness and vigor are compromised
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that simultaneously achieve compact plant habit (height and spread control) and high flower production. The cultivar 'Appofamcer' exhibits optimized parameters including compact growth form while producing numerous large flowers, resolving the contradiction between quantity and shape through genetic parameter selection.
2Area of moving object
If flower size is increased, then visual impact is improved, but flowering period duration is reduced
Solution Approach 1:
The patent resolves this contradiction through parameter changes in the plant's genetic makeup, where cultivar 'Appofamcer' has been bred to simultaneously achieve large flower size (5-7 cm diameter) and extended flowering duration (6-8 weeks). This represents an optimization of multiple parameters including flower dimensions and temporal flowering characteristics that are typically trade-offs.
3Productivity
If plant vigor is increased, then growth rate is improved, but plant compactness is reduced
Solution Approach 1:
The patent applies parameter changes by selecting for specific growth parameters that decouple vigor from sprawl. The cultivar 'Appofamcer' exhibits vigorous productivity (rapid establishment and flowering) while maintaining compact dimensions (30-50 cm height and spread). This resolves the contradiction through optimized genetic parameters for growth rate versus plant architecture.
