Hydrangea Hokomaburlac Cultivar Red Inflorescences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Hydrangea macrophylla with red inflorescences and desirable characteristics such as sturdy flowers and dark-colored leaves, which existing cultivars do not adequately provide.
Innovation Solution
A new cultivar, 'Hokomaburlac', is developed through controlled cross-breeding between 'Mysterious' and an unnamed plant, exhibiting dark-colored leaves, sturdy red inflorescences, and suitability for potted and cut flowers, achieved through asexual propagation by stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Hydrangea macrophylla cultivars are used, then general hydrangea characteristics are maintained, but red inflorescences with sturdy flowers and dark-colored leaves are not achieved
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific phenotypic traits including dark red inflorescence color, dark green leaf color, and increased flower sturdiness. The breeding program systematically selected plants exhibiting these desired parameter combinations, resulting in cultivars that simultaneously achieve multiple improved characteristics that were not present in parent cultivars.
2Stability of the object's composition
If asexual propagation by stem cuttings is used, then genetic stability and true-to-type reproduction are achieved, but propagation time and effort are increased
Solution Approach 1:
The patent employs preliminary action by performing asexual propagation through stem cuttings early in the cultivar development process to establish genetically stable, true-to-type plants before further breeding or commercial distribution. This preliminary propagation step ensures that the desired traits are fixed and will be consistently reproduced in subsequent generations, preventing genetic variation that would occur with sexual reproduction.
