Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Mandevilla plants lack compact growth and consistent flowering characteristics, with limited color variation and performance in garden settings.
Innovation Solution
Development of a new Mandevilla cultivar 'TVMD1626' through controlled cross-pollination, exhibiting upright to outwardly spreading habit, moderately vigorous growth, early and continuous flowering, and pale yellowish pink flowers with red throats, suitable for container and garden use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Mandevilla plants are used, then they have basic growth and flowering characteristics, but they lack compact growth and consistent flowering with limited color variation
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific growth parameters (compact habit, vigorous growth rate) and flowering parameters (continuous blooming, flower size, color intensity). The new cultivar 'TVMD1626' exhibits optimized parameters including compact upright growth habit, vigorous growth rate, and continuous flowering with pale yellowish-pink flowers featuring red throats, resolving the contradiction between adaptability and plant shape.
2Adaptability or versatility
If existing Mandevilla varieties are used, then they have certain flower colors, but they lack distinct color variation and good garden performance
Solution Approach 1:
The patent employs preliminary action through a systematic breeding program that pre-selects parent plants with desirable traits (TVMD1141 and TVMD736) before crossing. The controlled cross-pollination and subsequent selection process preliminarily establishes the genetic foundation for the new cultivar's superior garden performance and distinctive pale yellowish-pink flower color with red throats, making the breeding process more efficient and targeted.
3Reliability
If new cultivar 'TVMD1626' is developed through controlled cross-pollination, then it exhibits improved garden performance and distinct flower colors, but it requires complex breeding procedures
Solution Approach 1:
The patent implements feedback mechanisms through continuous observation and evaluation of progeny plants during the breeding program. The inventor monitored flowering patterns, growth habits, and flower colors across multiple generations, using this feedback information to select and propagate plants that consistently exhibited the desired pale yellowish-pink flowers with red throats and compact vigorous growth. This feedback-driven selection ensures reliable true-to-type characteristics while managing breeding program complexity through systematic documentation and selection criteria.
