Mandevilla Cultivar Breeding for Compact Habit and Free Flowering
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 new cultivars with improved floral and growth traits.
Innovation Solution
A new Mandevilla cultivar, 'TVMD1573', resulting from a controlled cross-pollination of proprietary selections TVMD1141 and TVMD1027, exhibits upright to outwardly spreading habit, moderately vigorous growth, early and continuous flowering, and yellow to light orange flowers, distinguishing it from its parents and other varieties like 'Sunpapri'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Mandevilla plants are grown, then they exhibit natural growth patterns, but they lack compact growth with large, freely flowering characteristics
Solution Approach 1:
The patent applies parameter changes by selectively breeding plants with specific genetic traits that modify growth parameters. The new cultivar 'TVMD1573' exhibits altered plant habit parameters (upright to outwardly spreading) and flowering parameters (early and continuous) through controlled cross-pollination and selection, resolving the contradiction between natural growth patterns and desired compact, productive characteristics
2Area of moving object
If Mandevilla plants are bred for large flowers, then flower size increases, but garden performance may be compromised
Solution Approach 1:
The patent applies local quality by developing a cultivar with differentiated characteristics in specific regions of the plant. The new cultivar 'TVMD1573' produces large flowers (7-8 cm diameter) with unique coloration patterns (yellow to light orange with reddish orange throats) while maintaining overall plant vigor and adaptability for garden performance, allowing large flowers without compromising reliability
3Ease of manufacture
If new cultivars are developed through cross-pollination, then unique floral characteristics are achieved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination between selected parent plants (TVMD1141 and TVMD1027) with known desirable traits before full-scale propagation. This preliminary breeding step allowed the development of 'TVMD1573' with predetermined characteristics (flower size, color, plant habit) before committing to extensive multiplication, reducing overall breeding time and complexity
