Osteospermum Cultivar SUNOST1704 Stable Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Osteospermum plants with compact and uniformly mounded growth habits, attractive flowering characteristics, and specific coloration that can reproduce stably and perform well in various environmental conditions.
Innovation Solution
A new cultivar, 'SUNOST1704', is developed through asexual reproduction of a naturally occurring branch mutation of Osteospermum ecklonis 'SUNOST1302', exhibiting a compact, upright to spreading growth habit, dark green leaves, freely branching and flowering, and deep red ray florets, which are stable across generations and environmental variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If asexual reproduction is used to propagate the new Osteospermum cultivar, then the unique features are stable and reproduced true to type, but the breeding process requires controlled greenhouse environment and multiple generations of verification
Solution Approach 1:
The patent uses asexual reproduction through terminal cuttings to create genetically identical copies of the selected mutation plant. This copying process ensures that the unique features (deep red ray florets, compact mounded habit, freely flowering) are reproduced true to type across generations, maintaining stability of the cultivar's composition.
Solution Approach 2:
The patent performs preliminary verification of the mutation's stability through multiple generations of asexual reproduction in controlled greenhouse conditions before formal recognition. This preliminary action ensures that the unique features are stable and can be reliably propagated, reducing future verification needs.
2Shape
If the Osteospermum plant is bred for compact and uniformly mounded plant habit with freely flowering characteristics, then the aesthetic and ornamental value is improved, but the breeding complexity and selection process increases
Solution Approach 1:
The patent focuses on selecting and propagating a specific local quality (compact mounded plant habit) from the parent cultivar. By concentrating breeding efforts on this particular trait along with the mutation-induced deep red floret color, the program achieves distinctive ornamental value without requiring complex multi-trait manipulation.
Solution Approach 2:
The patent utilizes a naturally occurring branch mutation that changed the ray floret color parameter from purple/red-purple to deep red. This parameter change, combined with selection for compact mounded habit, created the new cultivar's distinctive characteristics through targeted parameter modification rather than complex breeding interventions.
3Ease of manufacture
If the Osteospermum cultivar is selected for deep red ray floret coloration, then the color attractiveness and market distinction are improved, but the differentiation from parent and similar cultivars requires detailed botanical description and comparison
Solution Approach 1:
The patent is based on a naturally occurring mutation that changed the ray floret color from purple/red-purple to deep red. This color change is the defining characteristic of the new cultivar and provides immediate visual distinction from the parent cultivar SUNOST1302 and similar varieties, enhancing market appeal and ease of identification.
Solution Approach 2:
Instead of relying on complex mechanical or structural differences for cultivar differentiation, the patent uses color as the primary distinguishing feature. The deep red ray floret color serves as a readily detectable and measurable trait that simplifies cultivar identification and differentiation from parent and similar cultivars.
