Mandevilla hybrida 'Lancolorado' Breeding for Trailing Habit and Flower Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Mandevilla plant cultivars with attractive flowers that exhibit a unique combination of upright to trailing habit, moderately vigorous growth, glossy dark green leaves, and distinct flower colors, which existing cultivars such as 'Sunparapibra' and 'Sunmanderemi' do not fully meet.
Innovation Solution
The development of Mandevilla hybrida 'Lancolorado' through controlled cross-pollination between Mandevilla hybrida 'Sunparapibra' and 'Sunmanderemi', resulting in a plant with a more trailing habit, larger and darker pink flowers, and larger leaves compared to its parents, and differing from 'Lannevada' in flower color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If cross-pollination between 'Sunparapibra' and 'Sunmanderemi' is conducted to create new Mandevilla cultivars, then flower size and flower color intensity are improved, but plant upright habit is worsened (more trailing)
Solution Approach 1:
The patent combines genetic material from two parent cultivars ('Sunparapibra' and 'Sunmanderemi') through controlled cross-pollination to create a new hybrid cultivar 'Lancolorado' that merges desirable traits including larger flowers and enhanced color intensity while accepting the trailing habit as part of the overall aesthetic outcome
2Quantity of substance
If cross-pollination is conducted to achieve darker flower colors, then flower color intensity is improved, but flower color distinction from existing cultivars may be reduced
Solution Approach 1:
The patent specifically targets color enhancement through selective breeding, producing flowers with deeper, more saturated pink tones (described as 'dark pink' or 'magenta-pink') that distinguish 'Lancolorado' from lighter-flowered cultivars while maintaining sufficient differentiation from other dark-flowered varieties through the specific hue and intensity combination
3Area of moving object
If new Mandevilla cultivars are developed with larger flowers, then flower size is improved, but plant vigor may be reduced
Solution Approach 1:
The patent achieves a balance between flower size and plant vigor by selecting parent cultivars with complementary traits and evaluating multiple progeny, ultimately identifying 'Lancolorado' which exhibits moderately vigorous growth that supports its larger-than-average flowers without causing excessive trailing or weak structural development
