Mandevilla Lannevada Cultivar Red Flower Sun Fading Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new trailing Mandevilla plants with red-colored flowers that exhibit improved leaf thickness, resistance to sun fading, and earlier flowering habits compared to existing cultivars.
Innovation Solution
A new cultivar, 'Lannevada', resulting from a cross-pollination between Mandevilla sanderi 'Sunmanderemi' and a proprietary selection of Mandevilla sanderi, characterized by a trailing habit, glossy dark green leaves, and red flowers resistant to sun fading, which are stable and reproduce true to type through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing Mandevilla cultivars are used, then they have basic flowering capability, but they lack red-colored flowers and have thin leaves that fade in sunlight
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that confer red flower coloration and enhanced pigmentation. The new cultivar 'Lannevada' exhibits changed parameters in flower color (red versus pink or other colors in parent plants), leaf thickness, and pigmentation concentration that provide resistance to sun fading, thereby resolving the contradiction between ease of manufacture and reliability against environmental degradation.
Solution Approach 2:
The patent creates a composite genetic structure by cross-pollinating two different Mandevilla sanderi parent plants with distinct traits. The resulting cultivar 'Lannevada' combines genetic material from both parents, producing a composite plant with improved characteristics including red flower color, thicker leaves, and enhanced sun resistance that neither parent possessed alone, thus resolving the contradiction between manufacturability and durability.
2Productivity
If existing Mandevilla cultivars are used, then they have established growth patterns, but they lack early flowering habit and trailing growth pattern
Solution Approach 1:
The patent applies parameter changes by breeding for altered developmental timing parameters. The new cultivar 'Lannevada' exhibits changed parameters in flowering time (earlier flowering), growth rate (more vigorous), and growth pattern (trailing versus upright), achieving earlier productivity while maintaining stable and consistent trailing growth habit through selective breeding and genetic stabilization.
3Adaptability or versatility
If parent cultivars are used for breeding, then genetic diversity is introduced, but flower color and leaf characteristics become inconsistent
Solution Approach 1:
The patent applies feedback by implementing a systematic selection process where plants exhibiting the desired red flower color, thick leaves, and trailing growth habit are identified and selected from the progeny. This feedback loop of selection and reproduction continues over multiple generations to stabilize the new cultivar 'Lannevada', ensuring that the introduced genetic variation produces consistent, reliable traits rather than random variation.
