Regal Geranium Regcan Breeding for Cooling-Free Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Regal Geranium cultivars require cooling treatments for flower development, limiting their adaptability and uniformity under varying environmental conditions.
Innovation Solution
The development of a new Regal Geranium cultivar, 'Regcan', which results from a breeding program that eliminates the need for cooling treatments, characterized by an upright and vigorously growing plant with light and dark red-purple bi-colored flowers, and stable asexual reproduction through vegetative terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooling treatment is applied for flower development, then flower development is achieved, but environmental adaptability deteriorates
Solution Approach 1:
The patent applies parameter changes by modifying the genetic parameters of the Regal Geranium through selective breeding. The cultivar 'Regcan' possesses altered physiological parameters that enable flower development without external cooling treatment, thereby resolving the contradiction between reliable flower development and environmental adaptability.
2Reliability
If cooling treatment is required for flower development, then flower development is achieved, but production complexity increases
Solution Approach 1:
The patent applies the extraction principle by removing the requirement for cooling treatment from the flower development process. The cultivar 'Regcan' has been bred to inherently lack the physiological dependency on cooling periods, thereby simplifying production procedures while maintaining reliable flower development.
3Adaptability or versatility
If parent selections are used for breeding, then genetic diversity is maintained, but uniformity deteriorates
Solution Approach 1:
The patent applies preliminary action through a systematic breeding program that pre-selects and pre-evaluates progeny for specific uniform traits. The cultivar 'Regcan' was developed through multiple generations of selective breeding, where plants exhibiting uniform characteristics (upright habit, bi-colored flowers, no cooling requirement) were selected and propagated vegetatively to ensure consistency.
