Hydrangea HISHA Stem Strength and Longevity Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hydrangea macrophylla cultivars lack sturdy stems and good post-production longevity, which limits their durability and longevity in various environmental conditions.
Innovation Solution
The development of a new Hydrangea macrophylla cultivar 'HISHA' through controlled breeding, characterized by upright and spreading habit, strong greyed purple stems, freely branching, and dense dark purplish pink inflorescences with improved stem strength and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional Hydrangea macrophylla cultivars are used, then they can be grown and reproduced, but they lack sturdy stems and good post-production longevity
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in sturdier stems and enhanced longevity. The new cultivar 'HISHA' exhibits stem strength and longevity characteristics that differ from conventional cultivars through controlled breeding programs that modify genetic parameters.
Solution Approach 2:
The patent employs composite materials in the sense of combining desirable genetic traits from different parent plants through cross-breeding. The new cultivar combines characteristics that produce both sturdy stems and good post-production longevity, creating a composite genetic structure that achieves multiple desirable properties simultaneously.
2Reliability
If existing Hydrangea cultivars are propagated, then they can be reproduced, but they do not maintain vigor and flower substance under diverse environmental conditions
Solution Approach 1:
The patent uses parameter changes by breeding plants with modified genetic parameters that enhance both longevity and environmental adaptability. The new cultivar 'HISHA' demonstrates improved reliability across diverse environmental conditions through selective breeding that optimizes genetic parameters for resilience and adaptability.
3Strength
If conventional breeding methods are used, then new cultivars can be developed, but achieving both sturdy stems and good post-production longevity is difficult
Solution Approach 1:
The patent applies preliminary action through controlled breeding programs that pre-select parent plants with desirable traits before cross-pollination. By preparing and selecting specific parent plants (code number 1342 and code number 1213) with complementary characteristics, the breeding process efficiently produces offspring with the desired combination of sturdy stems and good longevity.
Solution Approach 2:
The patent employs feedback mechanisms by evaluating progeny plants for specific traits (stem strength, longevity, inflorescence quality) and selecting the best performers for further breeding. The new cultivar 'HISHA' was identified and selected based on feedback from observing which plants exhibited the desired combination of characteristics.
