Mandevilla FGVP1 Cultivar Vining Habit and Flower Color Mutation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct cultivar of Mandevilla splendens that exhibits a stronger vining habit and unique flower color, as existing cultivars like 'DIP 79' and 'Ginger' lack these specific traits.
Innovation Solution
A new cultivar, Mandevilla splendens 'FGVP1', which is a naturally occurring branch mutation of 'DIP 79', characterized by its strongly vining habit, medium green leaves, and pink flowers, is developed through asexual reproduction by tip cuttings, showcasing stability across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a new Mandevilla cultivar is developed with stronger vining habit, then the vining capability is improved, but the plant structure becomes more complex
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a mutation with altered growth parameters. The new cultivar 'FGVP1' exhibits changed internode length and vine elongation rates compared to the parent 'DIP 79', achieving stronger vining through natural genetic variation rather than structural modification
2Shape
If flower color is changed to pink, then the visual distinction is improved, but the genetic stability becomes more challenging to maintain
Solution Approach 1:
The patent uses asexual reproduction by tip cuttings to create exact genetic copies of the mutated plant. This copying method preserves the unique pink flower color mutation (different from parent's red) and ensures genetic stability across generations, as demonstrated by true-to-type reproduction since July 2008
3Area of stationary object
If the plant is selected for compact growth, then the space occupation is reduced, but the vining potential is limited
Solution Approach 1:
The patent captures a dynamic growth pattern where the plant transitions from compact initial growth to extended vining. The new cultivar 'FGVP1' exhibits dynamic characteristics with variable internode lengths that allow compact formation near the base while maintaining strong vining capability at higher growth stages
