Osteospermum Sunost1302 Cultivar Compact Habit and Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Osteospermum ecklonis cultivars lack a compact, uniformly mounded plant habit with attractive and consistent ray and disc floret coloration, and do not perform well under varying environmental conditions.
Innovation Solution
A new cultivar, 'Sunost1302', developed through cross-pollination of proprietary selections of Osteospermum ecklonis, exhibiting a compact, upright, and spreading growth habit with freely branching and flowering characteristics, featuring large daisy-type inflorescences with purple and red-purple ray florets, and demonstrating good garden performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Osteospermum ecklonis cultivars are used, then the plant can grow with typical growth habits, but the plant habit is not compact and uniformly mounded
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that produce compact, uniformly mounded growth habits. The inventor evaluated multiple progeny plants and selected those exhibiting the desired compactness and uniformity, which were then propagated through terminal cuttings to maintain stable, true-to-type characteristics across generations.
2Ease of manufacture
If existing Osteospermum ecklonis cultivars are used, then the plant can produce flowers, but the ray and disc floret coloration is not attractive and consistent
Solution Approach 1:
The patent utilizes parameter changes in floret coloration by selecting parent plants with desirable color traits and breeding them to produce progeny with consistent and attractive ray and disc floret coloration. The selected cultivar maintains stable color characteristics across generations, demonstrating true-to-type inheritance of color parameters.
3Adaptability or versatility
If existing Osteospermum ecklonis cultivars are used, then the plant can perform under typical conditions, but the performance varies under different environmental conditions
Solution Approach 1:
The patent applies parameter changes by selecting plants with genetic parameters that confer adaptability to varying environmental conditions. The selected cultivar demonstrates reliable performance across different environments, maintaining stable growth and flowering characteristics whether grown in containers or in the ground, and performing well in high temperatures and rain.
4Stability of the object's composition
If the new cultivar is propagated by terminal cuttings, then the unique features are stable and true-to-type, but the propagation process requires controlled environment
Solution Approach 1:
The patent applies the self-service principle by using terminal cuttings, which allow the plant to propagate itself through vegetative reproduction. The cuttings root independently without requiring sexual reproduction or complex breeding processes, maintaining stable, true-to-type characteristics while simplifying the propagation method to a straightforward cutting process that can be performed in controlled environments.
