Osteospermum Duetisuneye Compact Habit and Yellow Florets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact Osteospermum cultivars with uniform plant habit, early flowering, and interesting floret coloration that can reproduce stably through asexual methods, as existing cultivars may vary with environmental conditions and lack desired traits like compactness and vibrant floret colors.
Innovation Solution
The development of the Osteospermum ecklonis cultivar 'Duetisuneye' through planned breeding, achieved by crossing proprietary selections F-03-19 and F-01-13, which exhibits a compact, freely branching, and early flowering habit with bright yellow ray florets, and is stable through vegetative tip cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Osteospermum cultivars are used, then they may have some flowering traits, but they lack compactness and vibrant floret colors, and vary with environmental conditions
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that control plant height, branching density, and floret color intensity. The cultivar 'Duetisuneye' exhibits optimized parameters including reduced internode length for compactness, increased lateral branch density, and enhanced carotenoid pigmentation for vibrant yellow florets, while maintaining genetic stability across environmental conditions
2Ease of manufacture
If existing Osteospermum cultivars are used, then they may have some flowering traits, but they lack vibrant floret coloration
Solution Approach 1:
The patent applies color changes by enhancing the intensity and vibrancy of yellow pigmentation in ray florets through selective breeding. The cultivar 'Duetisuneye' displays markedly brighter yellow florets compared to parent selections, achieved through optimization of carotenoid biosynthesis pathways and increased pigment concentration in petal tissues, resulting in superior coloration that maintains saturation across varying environmental conditions
3Reliability
If asexual reproduction by vegetative tip cuttings is used, then the unique features are stable and reproduced true to type, but the breeding program requires controlled environment and time
Solution Approach 1:
The patent applies preliminary action by establishing genetically stabilized pure lines through controlled cross-pollination and selection before implementing asexual propagation. The breeding program pre-selects parent plants with desired traits, performs controlled crosses to fix genetic characteristics, and validates trait stability through multiple generations of vegetative propagation in controlled environments, ensuring that subsequent mass propagation yields consistent results without requiring ongoing environmental control
