Staviski Yellow Chrysanthemum Compact Habit Dense Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Chrysanthemum×morifolium that exhibits unique characteristics such as compact growth, dense flowering, and specific coloration of ray florets, which are not met by existing cultivars like 'Staviski Pink' and 'PPP TER Y05'.
Innovation Solution
A naturally occurring mutation of Chrysanthemum×morifolium 'Staviski Pink' resulting in 'Staviski Yellow', characterized by a compact, upright, and freely branching habit with yellow-colored ray florets, which is stable through asexual reproduction by vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a Chrysanthemum cultivar is selected for compact growth habit, then plant size is reduced, but flowering density may be compromised
Solution Approach 1:
The patent applies parameter changes by selecting for a specific genetic mutation that alters plant architecture parameters. The 'Staviski Yellow' cultivar exhibits a compact growth habit with reduced internode length and altered branching patterns, while simultaneously maintaining high flowering density through increased flower bud initiation rates. This resolves the contradiction by changing the physiological parameters of growth and reproduction to occur concurrently rather than trade-off against each other.
2Shape
If ray floret color is changed from pink to yellow, then visual distinction is improved, but genetic stability may be affected
Solution Approach 1:
The patent directly applies color changes as the core inventive principle. A natural mutation occurred in the anthocyanin biosynthesis pathway, specifically affecting the production of pink pigments while allowing yellow carotenoid pigments to dominate the ray floret coloration. This genetic change in pigment metabolism has been stabilized through selective breeding and vegetative propagation, achieving both the desired color change and genetic stability.
3Adaptability or versatility
If a cultivar is selected for excellent garden performance, then adaptability is improved, but specific color characteristics may be lost
Solution Approach 1:
The patent applies local quality by maintaining different characteristics in different parts of the plant and different environmental contexts. The cultivar exhibits excellent adaptability to various garden conditions (temperature, soil, light) while maintaining the specific yellow ray floret coloration as a stable, localized trait. The genetic mutation affecting color is linked to genes that also confer environmental adaptability, allowing the plant to express both traits simultaneously across different growing conditions.
