Hibiscus Extrmag Cultivar Breeding for Flower Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hibiscus moscheutos cultivars lack desirable traits such as large, attractive flowers and stable, true-to-type asexual reproduction, particularly in terms of branching habit, leaf color, and flower longevity.
Innovation Solution
A new cultivar, 'Extrmag', resulting from a cross-pollination between proprietary selections of Hibiscus moscheutos, exhibits an upright and spreading plant form, increased branching, darker green leaves, magenta-colored flowers with good longevity, and improved branching compared to parent selections, while differing in flower color and vigor from existing cultivars like 'Extrepink'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If cross-pollination is used to create new Hibiscus cultivars, then flower size and attractiveness can be improved, but stability of asexual reproduction and true-to-type characteristics deteriorate
Solution Approach 1:
The patent applies parameter changes by selecting specific parental lines with defined genetic characteristics and controlling the cross-pollination parameters (timing, environmental conditions, pollination methods) to achieve stable inheritance of desirable traits. The controlled environment and systematic selection process ensure that the new cultivar maintains true-to-type characteristics while exhibiting improved flower size and attractiveness.
2Shape
If plant form is made more freely branching, then aesthetic appearance and flower production are improved, but plant structure complexity and control difficulty worsen
Solution Approach 1:
The patent applies local quality by developing a freely branching habit that is localized to specific plant regions while maintaining overall structural integrity. The branching pattern is optimized in the upper portions of the plant where flowers are produced, while the root system and lower stems maintain controlled structure for stability and nutrient uptake.
3Shape
If flower color is changed to magenta, then aesthetic attractiveness is improved, but flower longevity and durability worsen
Solution Approach 1:
The patent applies composite materials by combining multiple genetic factors that work together to achieve both magenta flower color and extended longevity. The new cultivar integrates parental line characteristics that provide color stability and longevity genes, creating a composite genetic makeup that simultaneously delivers attractive magenta coloring and durable flower performance.
