Scaevola Duescalbu Cultivar Breeding for Compact Growth and Branching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a compact and freely branching Scaevola plant with attractive flowers that can perform well in various environmental conditions and cultural practices, as existing cultivars may not consistently exhibit desired traits under different temperature and light intensities.
Innovation Solution
A new cultivar, 'Duescalbu', was developed through planned breeding, resulting in a semi-compact, mounded, and outwardly spreading plant with freely branching and flowering habits, characterized by violet-colored flowers, achieved through cross-pollination of proprietary Scaevola aemula selections and stabilized through vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Scaevola cultivars are grown under varying environmental conditions, then their growth and flowering may be inconsistent, but achieving stable and consistent performance across different temperature and light conditions requires developing new cultivars with enhanced adaptability
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that confer stability across environmental variations. The new cultivar 'Duescalbu' exhibits consistent growth habits, branching patterns, and flowering characteristics despite variations in temperature and light intensity, indicating that genetic parameter optimization was achieved through the breeding program.
2Volume of moving object
If Scaevola plants are bred for compact growth habit, then plant size is reduced, but achieving both compactness and vigorous flowering requires balancing growth parameters
Solution Approach 1:
The patent applies local quality by creating a plant with non-uniform distribution of growth characteristics. The cultivar 'Duescalbu' exhibits compact overall plant size and volume while maintaining vigorous flowering capacity, indicating that different parts of the plant have been optimized for different functions - compact vegetative growth combined with prolific flowering.
3Device complexity
If Scaevola plants are bred for frequent branching, then plant architecture becomes more complex, but achieving both free branching and compact form requires optimizing branch development
Solution Approach 1:
The patent applies segmentation by dividing the plant architecture into multiple branching units. The cultivar 'Duescalbu' exhibits a freely branching habit with numerous lateral branches, creating a segmented plant structure that achieves compact overall volume through repeated modular branching patterns rather than single large growth structures.
