Mandevilla Cultivar With Large Flowers and Compact Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Mandevilla plants lack compact growth with large, freely flowering characteristics and good garden performance, necessitating the development of new cultivars with improved floral and growth traits.
Innovation Solution
A new Mandevilla cultivar, 'TVMD1232', resulting from a controlled cross-pollination of Mandevilla sanderi 'TVMD654' and a proprietary selection TVMD874, exhibits upright to outwardly spreading habit, moderately vigorous growth, early and continuous flowering, and orangish yellow flowers, distinguishing it from other cultivars like 'TVMD654' and 'Sunpapri'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing Mandevilla plants are used, then they have basic growth characteristics, but they lack compact growth with large, freely flowering characteristics and good garden performance
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic traits that produce compact growth habit combined with large flower size and high flowering frequency. The cultivar 'TVMD1232' exhibits optimized parameters including compact plant architecture, increased flower size, and enhanced flowering performance compared to parent plants, resolving the contradiction between plant habit and productivity.
2Area of moving object
If flower size is increased, then larger flowers are achieved, but plant compactness may be compromised
Solution Approach 1:
The patent applies local quality by concentrating genetic traits that promote large flower size specifically in the floral structures while maintaining separate genetic control over plant architecture and compactness. The cultivar 'TVMD1232' displays locally optimized characteristics where flowers are significantly larger than parent plants while the overall plant maintains a compact, controlled growth habit, allowing both traits to coexist without compromise.
3Productivity
If early and continuous flowering is achieved, then garden performance is improved, but genetic stability across generations must be maintained
Solution Approach 1:
The patent applies self-service through true-to-type vegetative propagation where rooted cuttings of cultivar 'TVMD1232' automatically reproduce the parent plant's superior flowering characteristics without requiring additional intervention. The genetically stable cultivar maintains early and continuous flowering habits across successive generations through asexual reproduction, ensuring consistent garden performance while preserving genetic stability. The plant essentially propagates itself with all desirable traits intact.
