Chrysanthemum Bronze San Remo Runner Rust Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Chrysanthemum cultivars face issues with varying plant habits and susceptibility to Rust pathogens, with limited options for cultivars offering greyed orange ray florets and extended flowering periods.
Innovation Solution
A new cultivar, 'Bronze San Remo Runner', is introduced, characterized by its uniform, upright growth habit, freely branching and flowering, greyed orange ray florets, and resistance to Rust pathogens, achieved through asexual reproduction by vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Chrysanthemum cultivars are used, then plant growth habit can be maintained, but susceptibility to Rust pathogens increases and flowering period is limited
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a specific plant mutation that has naturally altered genetic parameters, resulting in a cultivar with both Rust pathogen resistance and extended flowering period. The mutation in the plant's genetic code enables simultaneous expression of disease resistance and prolonged flowering capability.
2Stability of the object's composition
If asexual reproduction by vegetative cuttings is used, then stable and reproducible traits are achieved, but genetic diversity is reduced
Solution Approach 1:
The patent employs copying through asexual reproduction by vegetative cuttings, where new plants are produced as genetic copies of the parent plant. This copying process preserves the stable and reproducible traits of the mutation while maintaining uniformity across the cultivar population.
3Shape
If decorative-type inflorescences with greyed orange ray florets are developed, then aesthetic appearance is improved, but flowering time is advanced compared to parent cultivar
Solution Approach 1:
The patent applies color changes by describing the distinctive greyed orange coloration of the ray florets in the new cultivar. This color characteristic is a result of the plant mutation and is maintained through asexual reproduction, providing both aesthetic appeal and early flowering timing.
