Hydrangea Serrata Cultivar HSE1735301 Breeding for Stem Strength and Flower Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hydrangea cultivars lack compact and strong plants with attractive inflorescences and good post-production longevity, which are essential for improved garden performance and aesthetic appeal.
Innovation Solution
A new cultivar of Hydrangea serrata, 'HSE1735301', resulting from a cross-pollination between proprietary selections 12-00-203 and 12-00-205, exhibiting upright to broadly spreading habit, dark green leaves, freely branching and flowering, and unique flower colors, which are stable through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional Hydrangea cultivars are used, then existing varieties are available, but they lack compact and strong plant structure with attractive inflorescences and good postproduction longevity
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific genetic traits that modify plant structure strength, inflorescence attractiveness, and postproduction longevity. The cross-pollination between parental selections 12-00-203 and 12-00-205 combines genetic parameters to produce offspring with improved strength and reliability characteristics.
2Adaptability or versatility
If new traits are introduced through cross-pollination, then improved plant characteristics are achieved, but genetic stability across generations must be maintained
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination in a controlled greenhouse environment to预先 combine desired genetic traits before mass propagation. The single flowering plant discovered in August 2017 was selected and then propagated asexually through terminal vegetative cuttings since August 2018, ensuring genetic stability while introducing new traits.
Solution Approach 2:
The patent applies copying by using asexual reproduction through terminal vegetative cuttings to replicate the selected plant's genetic composition. This method copies the exact genetic makeup of the parent plant, ensuring that the unique features are stable and reproduced true to type in successive generations without genetic variation.
3Stability of the object's composition
If asexual reproduction is used to propagate the new cultivar, then genetic consistency is maintained, but the ability to adapt to different environmental conditions may be limited
Solution Approach 1:
The patent addresses this contradiction by selecting parental plants with complementary traits that provide both genetic consistency and environmental adaptability. The cross-pollination combines genetic parameters for stability while incorporating adaptive traits from both parents, allowing the propagated cultivar to maintain genetic consistency through cutting while possessing inherent adaptability to various environmental conditions.
