Osteospermum Sunost1102 Cultivar Breeding for Heat Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Osteospermum cultivars lack compact and uniformly mounded plant habits with attractive inflorescence coloration and high temperature tolerance, leading to suboptimal garden performance.
Innovation Solution
Development of the new Osteospermum cultivar 'Sunost1102' through cross-pollination of proprietary selections, resulting in a compact, freely branching plant with greyed purple-colored ray florets and improved heat tolerance, achieved through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Osteospermum cultivars are used, then garden performance is achieved, but plant habit is not compact and uniformly mounded
Solution Approach 1:
The patent applies parameter changes by selecting and breeding Osteospermum plants with specific genetic parameters that produce compact, uniformly mounded plant habits. The cross-pollination between proprietary selections (05.70.001 and 04.70.004) was designed to combine genetic traits that result in improved plant morphology while maintaining garden performance.
2Shape
If existing Osteospermum cultivars are used, then garden performance is achieved, but inflorescence coloration is not attractive
Solution Approach 1:
The patent utilizes parameter changes in inflorescence coloration by crossing proprietary selections with distinct color traits. The resulting cultivar 'Sunost1102' exhibits attractive inflorescence coloration that differs from both parent selections, demonstrating genetic recombination that produces novel color characteristics while maintaining garden performance.
3Temperature
If existing Osteospermum cultivars are used, then garden performance is achieved, but temperature tolerance is insufficient
Solution Approach 1:
The patent applies parameter changes in temperature tolerance through the selection and cross-pollination of proprietary selections that possess enhanced heat tolerance traits. The new cultivar 'Sunost1102' demonstrates improved tolerance to high temperatures compared to parent selections, while maintaining reliable garden performance through controlled breeding.
4Stability of the object's composition
If asexual reproduction by terminal cuttings is used, then stable true-to-type characteristics are achieved, but propagation time is extended
Solution Approach 1:
The patent applies the self-service principle through asexual reproduction by terminal cuttings, where the plant propagates itself without requiring sexual reproduction or external intervention. This method ensures stable, true-to-type characteristics are maintained in successive generations, though it does require time for cutting propagation to occur.
