Mandevilla Cultivar With Compact Growth and Early Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Mandevilla plants lack compact growth and consistent, large, freely flowering characteristics, with variations in flower color and size among different cultivars, limiting their garden performance and aesthetic appeal.
Innovation Solution
Development of a new Mandevilla cultivar 'TVMD714' through controlled cross-pollination, exhibiting upright to outwardly spreading habit, moderately vigorous growth, and yellow-orange flowers, which are larger and more consistent in size and color compared to existing cultivars.
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 large flower characteristics are lacking
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic parameters through controlled cross-pollination between parent plants TVMD317 and TVMD518. The breeding program targeted specific parameters including plant height (30-45 cm), flower diameter (5-7 cm), and flowering frequency to achieve the desired compact growth with consistent large flowers.
2Duration of action of moving object
If existing Mandevilla cultivars are used, then flower variety is available, but early and continuous flowering is not achieved
Solution Approach 1:
The patent applies preliminary action through pre-breeding selection of parent plants with desirable flowering characteristics. The parent plants TVMD317 and TVMD518 were specifically selected and prepared before cross-pollination to ensure the progeny would inherit early and continuous flowering traits, which were then stabilized through subsequent generations of asexual reproduction.
3Reliability
If existing Mandevilla cultivars are used, then plant diversity is maintained, but garden performance is limited
Solution Approach 1:
The patent applies self-service through the development of a self-contained breeding system that produces uniform, reliable plants. The new cultivar 'TVMD714' exhibits stable characteristics through asexual reproduction, requiring minimal intervention and maintenance while providing consistent garden performance. The plant's compact size and continuous flowering capability enable it to thrive in various garden conditions with standard care.
