Mandevilla Cultivar Selection for Compact Habit and White Blooms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Mandevilla plants lack compact growth and consistent flowering characteristics, with variations in flower color and size among different cultivars, limiting their suitability for specific gardening applications.
Innovation Solution
Development of a new Mandevilla cultivar 'TVMD944' through controlled cross-pollination, exhibiting upright growth, moderate vigor, and consistent white flowers with orangish-yellow throats, suitable for container and garden use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Mandevilla cultivars are used, then various flower colors and sizes are available, but compact growth and consistent flowering characteristics are lacking
Solution Approach 1:
The patent applies parameter changes by selectively breeding Mandevilla plants to modify specific growth parameters (compactness, flowering consistency) while maintaining flower color and size diversity through controlled cross-pollination between parent plants with different characteristics
2Stability of the object's composition
If existing Mandevilla cultivars are used, then flower color variety is available, but consistent flowering characteristics are not achieved
Solution Approach 1:
The breeding program modifies flowering consistency parameters through selective cross-pollination, creating cultivars that maintain stable flowering patterns while preserving color variety through genetic combination of parent plants with different floral characteristics
3Shape
If existing Mandevilla cultivars are used, then large flowers can be obtained, but compact growth is not achieved
Solution Approach 1:
The patent applies local quality by creating plants with differentiated characteristics: compact overall growth habit combined with large flower size, achieving local optimization of both growth compactness and flower dimensions through selective breeding of specific parental lines
