Argyranthemum SUN 410 Cultivar Uniform Mounded Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Argyranthemum plants lack uniformity and attractive ray and disc floret colors, and have variable garden performance and pest susceptibility.
Innovation Solution
A new cultivar, 'SUN 410', is developed through cross-pollination of unnamed seedling selections of Argyranthemum frutescens, exhibiting a uniformly mounded, freely branching, and freely flowering habit with red-purple ray florets, improved garden performance, and stability in asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cross-pollination of unnamed seedling selections is performed, then attractive ray and disc floret colors are achieved, but uniformity of plant habit is insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic parameters through asexual reproduction. The new cultivar 'SUN 410' maintains consistent plant habit parameters (mounded form, branching patterns) and floret color parameters (red-purple ray florets) across generations, transforming variable parent selections into a uniform commercial cultivar through selective propagation
Solution Approach 2:
The patent applies local quality by differentiating between various plant traits and optimizing them independently. The cultivar exhibits uniformly mounded plant habit, freely branching habit, and red-purple ray florets as distinct localized characteristics, allowing each trait to be evaluated and stabilized separately to achieve overall uniformity
2Ease of manufacture
If new cultivars are developed through cross-pollination, then attractive floret colors are achieved, but garden performance variability increases
Solution Approach 1:
The patent stabilizes garden performance parameters through asexual reproduction. The new cultivar 'SUN 410' demonstrates consistent garden performance including good rain tolerance, wind tolerance, and pest resistance across multiple generations, transforming variable parent selections into a reliable commercial product with predictable field behavior
Solution Approach 2:
The patent applies self-service through the plant's inherent pest resistance and environmental tolerance. The cultivar exhibits good garden performance and pest resistance without requiring additional interventions, allowing the plant to maintain itself reliably in garden conditions
3Stability of the object's composition
If asexual reproduction by vegetative tip cuttings is conducted, then genetic stability is achieved, but time for propagation increases
Solution Approach 1:
The patent applies preliminary action by preparing and propagating plants during optimal seasonal conditions. Rooting is conducted in February 2014 with temperature control (18°C to 24°C in summer, 14°C to 18°C in winter), and plants are pinched five weeks after planting to enhance lateral branch development, optimizing the propagation timeline
Solution Approach 2:
The patent optimizes propagation parameters including temperature (18°C to 24°C for summer rooting, 14°C to 18°C for winter rooting), timing (8 to 10 days for root initiation in summer, 10 to 15 days in winter), and cultural practices (pinching five weeks after planting) to achieve efficient asexual reproduction while maintaining genetic stability
