Radiant Time Chrysanthemum Breeding for Shelf Life and Flower Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Chrysanthemum varieties lack distinct characteristics such as flower size, inflorescence height, growth rate, and shelf life, which are essential for commercial cultivation and market differentiation.
Innovation Solution
The development of the 'Radiant Time' Chrysanthemum variety, which exhibits medium-sized yellow and red ray florets, larger and taller inflorescence, quicker response time, and medium vigor, achieved through controlled breeding and asexual reproduction, distinguishing it from parent varieties like Machismo Time and Swing Time Dark.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Chrysanthemum varieties are used for commercial cultivation, then they have established growth characteristics, but they lack distinct characteristics in flower size, inflorescence height, growth rate, and shelf life
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific quantitative traits including flower size (7-9 cm diameter), inflorescence height (15-20 cm), growth rate (7-10 weeks to bloom), and shelf life (14-21 days). These parameter modifications create distinct characteristics that differentiate the variety from conventional chrysanthemums in commercial markets
2Volume of moving object
If Chrysanthemum varieties with larger flowers and taller inflorescence are developed, then market appeal is improved, but growth rate and response time may be reduced
Solution Approach 1:
The patent resolves this contradiction by optimizing the interrelationship between flower size parameters and growth rate parameters. The variety achieves medium-large flowers (7-9 cm) with medium vigor and a balanced growth rate of 7-10 weeks to bloom, demonstrating that parameter optimization rather than extreme values achieves the desired balance between market appeal and commercial productivity
3Duration of action of stationary object
If Chrysanthemum varieties with extended shelf life are developed, then commercial viability is enhanced, but other characteristics such as flower form may be compromised
Solution Approach 1:
The patent resolves this contradiction by establishing optimal parameter ranges where shelf life (14-21 days) is extended while maintaining acceptable flower form characteristics (single flowers, flat to slightly cupped). The breeding program optimizes the relationship between shelf life and flower form parameters rather than maximizing one at the expense of the other
