Fire Sprinter Chrysanthemum Uniform Ray Floret Color and Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Chrysanthemum cultivars lack unique and attractive ray floret coloration and have variable flowering times and habits, which limits their ornamental value and adaptability in different environmental conditions.
Innovation Solution
The development of the Chrysanthemum×morifolium 'Fire Sprinter' cultivar, resulting from a cross-pollination between 'Early Surfer' and 'Padre', exhibits a uniform, upright growth habit, dense flowering, bright greyed red ray florets, and an extended flowering period, distinguishing it from its parents and other cultivars like 'Fuschini Red'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing Chrysanthemum cultivars are used, then they have basic flowering characteristics, but they lack unique and attractive ray floret coloration and have variable flowering times
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific phenotypic parameters including ray floret color (bright greyed red), flowering time (earlier flowering by about five days), and plant habit (uniform, upright, outwardly spreading). These parameter selections resolve the contradiction by establishing fixed, desirable values for both coloration uniformity and flowering time consistency.
Solution Approach 2:
The patent applies local quality by focusing on specific local characteristics of the plant: the ray floret coloration, the flowering time, and the plant habit. By optimizing these specific local qualities rather than overall plant characteristics, the patent achieves unique greyed red ray florets with uniform coloration while maintaining consistent flowering time across plants.
2Volume of stationary object
If existing Chrysanthemum cultivars are used, then they have standard inflorescence size, but they lack larger inflorescences with extended flowering period
Solution Approach 1:
The patent applies merging by combining multiple desirable traits from parent plants into a single cultivar. The 'Fire Sprinter' cultivar merges the early flowering trait from one parent with the bright greyed red ray floret coloration and uniform habit from another parent, achieving a combination of larger inflorescences and extended flowering period that neither parent possessed alone.
Solution Approach 2:
The patent applies composite materials conceptually by creating a composite genotype that combines genetic material from multiple parents to produce a plant with superior composite phenotypic characteristics including larger inflorescences, extended flowering period, and unique coloration that is greater than the sum of individual parental traits.
3Shape
If existing Chrysanthemum cultivars are used, then they have basic growth habit, but they lack uniform, upright, outwardly spreading habit with dense flowering
Solution Approach 1:
The patent applies parameter changes by selecting for specific morphological parameters including plant height, width, branching pattern, and inflorescence distribution. The resulting cultivar exhibits a uniform, upright, outwardly spreading habit with dense flowering, representing optimized values for these shape parameters that simultaneously improve flowering uniformity and reliability.
