Pobo Red Chrysanthemum Cultivar Breeding via Spontaneous Mutation
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, early and uniform flowering, and distinct dark red-colored ray florets, which are not met by existing cultivars like 'PPP POB LV05' and 'Gedi Two Cam'.
Innovation Solution
A naturally occurring whole plant mutation of Chrysanthemum×morifolium 'PPP POB LV05', named 'Pobo Red', which displays a compact, upright, and freely branching habit with large semi-double inflorescences featuring dark red ray florets, differing from its parent in ray floret color and showing improved leaf size and flowering timing compared to 'Gedi Two Cam'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a new Chrysanthemum cultivar is developed with distinct dark red ray florets, then flower color differentiation is improved, but breeding complexity increases
Solution Approach 1:
The patent applies parameter changes by selecting for a specific color parameter (dark red ray florets) in a naturally occurring mutation. The cultivar 'Pobo Red' was discovered as a spontaneous mutation of 'PPP POB LV05' that exhibits distinct dark red ray florets instead of lavender, representing a change in the color parameter without requiring complex breeding interventions
Solution Approach 2:
The invention utilizes self-service by relying on a naturally occurring whole plant mutation rather than artificial breeding techniques. The mutation occurred spontaneously in the population, and the inventor simply needed to identify and select the mutant plant, allowing nature to perform the complex genetic modification work
2Shape
If a compact and freely branching plant habit is achieved, then plant density and fullness are improved, but growth control difficulty increases
Solution Approach 1:
The patent applies parameter changes by selecting for specific growth parameters in the mutant plant. The 'Pobo Red' cultivar exhibits a compact overall size with upright stems that are outwardly spreading and freely branching, creating a dense and full plant habit. These morphological parameters were naturally altered in the mutation and were selected for during breeding
3Stability of the object's composition
If early and uniform flowering is achieved, then flowering consistency is improved, but environmental adaptability requirements increase
Solution Approach 1:
The patent applies parameter changes by selecting for flowering time parameters in the mutant plant. The 'Pobo Red' cultivar exhibits early and uniform flowering behavior, with inflorescences appearing consistently across the plant population. This flowering parameter was naturally altered in the mutation and selected during the breeding process to achieve uniformity
4Shape
If large semi-double inflorescences with dark red ray florets are produced, then flower quality is improved, but reproductive energy consumption increases
Solution Approach 1:
The patent applies parameter changes by selecting for inflorescence quality parameters in the mutant plant. The 'Pobo Red' cultivar produces large semi-double inflorescences with prominent dark red ray florets, representing improved flower quality parameters. The semi-double flower form and intense coloration are natural characteristics of the mutation that were selected during breeding
