Mandevilla Cultivar With Large Flowers and Stable Garden Performance
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 a new cultivar with improved floral size and color variation.
Innovation Solution
A new Mandevilla cultivar, 'TVMD1143', resulting from a controlled cross-pollination of proprietary selections TVMD832 and TVMD733, exhibits upright to outwardly spreading habit, moderately vigorous growth, early and continuous flowering, and yellowish pink to pale yellow flowers with reddish orange throats, distinguishing it from its parents and other varieties like '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 growth habit parameters (compact, upright to outwardly spreading) and flowering parameters (large flower size, frequent flowering). The new cultivar 'TVMD1143' exhibits these optimized parameters resulting from controlled cross-pollination and selective breeding, achieving both compact growth and high flowering performance simultaneously
2Area of moving object
If existing Mandevilla plants are used, then they have basic flower size, but they lack large flowers with good garden performance
Solution Approach 1:
The patent changes the flower size parameter by breeding from selected parent plants to produce 'TVMD1143' with notably larger flowers. The new cultivar maintains reliability in garden performance through stable inheritance of desirable traits including vigor, disease resistance, and adaptability to growing conditions, achieving both large flower size and reliable garden performance
3Ease of manufacture
If existing Mandevilla plants are used, then they have basic color characteristics, but they lack yellowish pink to pale yellow flowers with reddish orange throats
Solution Approach 1:
The patent changes the color parameters by crossing parent plants with different color characteristics to produce 'TVMD1143' with its distinctive yellowish pink to pale yellow petals and reddish orange throat. The color composition is stable and true-to-type, consistently reproducing in successive generations through asexual reproduction, achieving both color variation and stability
4Productivity
If existing Mandevilla plants are used, then they have basic growth vigor, but they lack moderately vigorous to vigorous growth habit with early and continuous flowering
Solution Approach 1:
The patent changes the flowering parameters by breeding 'TVMD1143' to exhibit moderately vigorous to vigorous growth habit that supports early and continuous flowering. The new cultivar produces flowers repeatedly over extended periods, maintaining high flowering frequency and duration, achieving both productivity and temporal duration of flowering action
