Geranium Cultivar Duevililav Breeding for Vigor and Compactness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Zonal Geranium cultivars lack vigorous growth and attractive flower color variations, with existing cultivars being either too vigorous or compact, and having limited flower color options, which restricts their garden performance and aesthetic appeal.
Innovation Solution
A new cultivar, 'Duevililav', is developed through cross-pollination of proprietary selections of Pelargonium×hortorum, exhibiting a compact, vigorously growing plant with semi-double lavender flowers, distinct from its parents and 'Blue Wonder', offering improved garden performance and visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing Zonal Geranium cultivars are bred for vigorous growth, then growth vigor is improved, but plant compactness deteriorates
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific growth parameters - achieving vigorous growth (improved productivity) while maintaining compact plant form (controlled volume). The new cultivar 'Duevililav' exhibits this balance through controlled breeding from specific parent selections, optimizing both growth vigor and plant compactness simultaneously
2Volume of moving object
If existing Zonal Geranium cultivars are bred for compact size, then plant compactness is improved, but growth vigor deteriorates
Solution Approach 1:
The patent resolves this contradiction by changing the growth parameters through selective breeding. The new cultivar 'Duevililav' achieves both compact size and vigorous growth by selecting specific parental traits and combining them, demonstrating that compactness and vigor are not mutually exclusive when proper breeding parameters are applied
3Shape
If existing Zonal Geranium cultivars are bred for specific flower colors, then flower color attractiveness is improved, but flower color variety deteriorates
Solution Approach 1:
The patent applies composite principles by combining multiple flower color traits from different parent selections. The new cultivar 'Duevililav' with lavender flowers results from combining genetic material from parents with different color characteristics (violet parent F-01-22 and pink parent Z98-6031-3), creating a novel composite flower color that is both attractive and adds variety to the cultivar collection
