Hydrangea H212907 Cultivar Breeding for Stem Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hydrangea cultivars lack strong, sturdy stems and optimal branching habits, as well as consistent and attractive flower color, particularly in mophead-type varieties, which affects their commercial viability and aesthetic appeal.
Innovation Solution
A new cultivar, 'H212907', resulting from a controlled breeding program, exhibits upright and spreading growth, vigorous branching, strong stems, and mophead-type inflorescences with white flowers and light green margins, distinguishing it from parent selections and comparable varieties like 'Agrihydranegen' in terms of size, vigor, and sterile flower sepal color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional Hydrangea cultivars are used, then they can be grown and maintained, but they lack strong sturdy stems and optimal branching habits
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in stronger stems and more consistent branching habits. The new cultivar 'H212907' exhibits these improved parameters through controlled cross-pollination and selection of parent plants with desirable traits, fundamentally changing the genetic parameters of the Hydrangea population.
2Reliability
If conventional Hydrangea cultivars are used, then they can produce flowers, but they lack consistent and attractive flower color
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination experiments in advance to develop parent selections with stable flower color traits. The inventor performed preliminary breeding work involving multiple generations of selection and evaluation before finalizing the new cultivar, ensuring color consistency is established before commercial propagation.
Solution Approach 2:
The patent applies feedback mechanisms through systematic evaluation and selection of progeny plants based on observed flower color traits. The inventor monitored and selected plants that exhibited the desired light green margins and white centers, using this feedback information to guide further breeding decisions and ensure trait stability across generations.
3Duration of action of stationary object
If existing mophead-type Hydrangea varieties are used, then they provide ornamental value, but they lack optimal postproduction longevity
Solution Approach 1:
The patent applies this principle in reverse by developing a cultivar that extends the functional life of the flowers rather than accepting short longevity. Through selective breeding, the new cultivar 'H212907' produces flowers with enhanced durability and extended postproduction life, making the ornamental product last longer while maintaining trait stability through asexual reproduction.
