Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new, distinct variety of evergreen azalea that combines compact growth habit, cold hardiness, and attractive blooming characteristics, particularly with red-purple flowers, which can thrive in various conditions and be easily propagated.
Innovation Solution
The development of the Rhododendron azalea variety 'MNIHAR026' through planned cross hybridization between 'Conlec' and 'September Morn', exhibiting a compact, globose growth habit, red-purple flowers, and ease of propagation via semi-hardwood cuttings, suitable for both shade and sun, and hardy to Zone 6.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross hybridization is performed to combine desirable traits from parent plants, then the new variety exhibits improved characteristics (compact growth, cold hardiness, attractive flowers), but the breeding process requires significant time and multiple generations of selection
Solution Approach 1:
The patent performs preliminary cross hybridization between specifically selected parent plants ('Conlec' and 'September Morn') before field testing, pre-combining desirable traits of compact growth, cold hardiness, and flower characteristics. This preliminary genetic combination accelerates the breeding process by reducing the need for multiple generations of selection, directly producing plants with the target adaptability to diverse conditions.
2Adaptability or versatility
If the azalea variety is selected for compact growth habit and cold hardiness, then it becomes suitable for container growth and various zones, but the growth rate may be moderated compared to faster-growing varieties
Solution Approach 1:
The patent selects and breeds for specific parameter changes in the azalea variety, including compact growth habit, cold hardiness to Zone 6, and moderate growth rate. These parameter changes make the plant suitable for container growth and various hardiness zones, trading off rapid growth for adaptability and ornamental value. The hybridization between 'Conlec' and 'September Morn' specifically targets these parameter combinations.
3Adaptability or versatility
If the azalea is bred for prolific blooming with hose-in-hose flowers, then aesthetic appeal is enhanced, but energy and nutrients are diverted from vegetative growth
Solution Approach 1:
The patent applies local quality by concentrating ornamental features (hose-in-hose flowers, red-purple coloration, compact habit) in specific regions of the plant while maintaining moderate overall growth. The hybridization focuses on enhancing flower quality and compactness in the vegetative portions, allowing the plant to achieve high aesthetic appeal without completely sacrificing vegetative development, as the compact growth habit itself becomes an ornamental feature suitable for containers.
