Mandevilla Cultivar Selection for Stable Large-Flower Free Blooming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact and freely flowering Mandevilla plants with large flowers and good garden performance, as existing varieties may lack these desirable traits.
Innovation Solution
A new cultivar of Mandevilla sanderi, named 'TVMD1330', developed through controlled cross-pollination and asexual reproduction, exhibiting upright to outwardly spreading habit, moderately vigorous growth, early and continuous flowering, deep purplish pink flowers with dark yellow throats, and suitable for containers and gardens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Mandevilla varieties are used, then they may have large flowers, but they lack compact growth habit and free flowering
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic combinations that alter growth parameters. The new cultivar 'TVMD1330' exhibits a compact growth habit parameter while simultaneously maintaining high flowering frequency, achieving a parameter optimization that balances plant size with productivity.
2Productivity
If existing Mandevilla varieties are used, then they may have vigorous growth, but they produce fewer flowers
Solution Approach 1:
The breeding program optimizes the relationship between growth vigor and flowering frequency by selecting plants with modified growth parameters. The new cultivar achieves moderate vigor that directs energy toward flower production rather than excessive vegetative growth, resolving the trade-off between strength and productivity.
3Shape
If existing Mandevilla varieties are used, then they may have large flowers, but they lack stability in reproduction
Solution Approach 1:
The patent uses asexual reproduction through stem cuttings to create exact genetic copies of the selected plant. This copying method ensures that the desirable flower size and color characteristics are perfectly replicated in successive generations, achieving both large flowers and reproduction stability.
Solution Approach 2:
Instead of relying on seed reproduction which introduces genetic variation, the patent inverts the approach by using vegetative propagation. This inversion of the reproduction method ensures genetic identicality and stability while maintaining the desired flower characteristics.
