Hydrangea H216906 Cultivar Stem Strength and Flower Abundance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hydrangea cultivars lack strong, sturdy stems and abundant, long-lasting, showy sterile flowers with desired color and branching habits, which limits their ornamental value and durability.
Innovation Solution
A new Hydrangea macrophylla cultivar 'H216906' with upright and rounded habit, vigorous growth, freely branching stems, early and uniform flowering, mophead-type inflorescences with numerous double-type bright red-purple sterile flowers, and good post-production longevity, achieved through controlled breeding and vegetative propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional Hydrangea cultivars are used, then they have basic ornamental features, but they lack strong sturdy stems and abundant long-lasting showy sterile flowers with desired color and branching habits
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific genetic traits that modify stem strength, flower abundance, flower color, and branching habits. The breeding program changed key parameters including stem thickness, inflorescence size, sterile flower quantity, and color intensity to achieve superior ornamental value and durability
2Reliability
If conventional Hydrangea cultivars are used, then they have limited ornamental value, but they require complex breeding programs to improve stem strength and flower characteristics
Solution Approach 1:
The patent applies preliminary action by pre-selecting parent plants with desirable traits (strong stems, good branching) before crossing. The breeding program established a foundation of selected parents that already possessed key characteristics, reducing the complexity of subsequent breeding steps while achieving reliable ornamental value improvements
3Quantity of substance
If conventional Hydrangea cultivars are used, then they have moderate flower abundance, but they lack early and uniform flowering with good postproduction longevity
Solution Approach 1:
The patent applies parameter changes by breeding for genetic traits that control flowering time, flower set uniformity, and postproduction longevity. The selected cultivar exhibits early and uniform flowering with extended vase life, achieving both high flower abundance and prolonged durability through modified biological parameters
