Mandevilla Cultivar with Pink White Splashed Petals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Mandevilla cultivar 'Rita Marie Green' lacks variation in flower color and early flowering traits, limiting its horticultural appeal and adaptability to different environmental conditions.
Innovation Solution
A new cultivar, 'Rita Marie Otwell Green', is introduced, characterized by light pink and white-splashed petals and earlier flowering, distinguished from its parent by these unique traits, which are stable through successive generations via asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the Mandevilla cultivar 'Rita Marie Green' is used, then it has stable dark pink flowers, but it lacks flower color variation and early flowering traits
Solution Approach 1:
The patent applies parameter changes by selecting a natural mutant with altered flower color parameters (light pink instead of dark pink) and early flowering timing. This mutant exhibits changed phenotypic parameters while maintaining the species' fundamental characteristics, thus achieving color variation without complete loss of stability.
Solution Approach 2:
The patent introduces local quality changes by creating a specific color pattern with white splashes on pink petals, rather than uniform coloration. This localized variation in petal color distribution provides visual diversity while maintaining overall flower structure consistency.
2Productivity
If the Mandevilla cultivar 'Rita Marie Green' is propagated, then it maintains original traits, but it does not exhibit early flowering or increased flower production
Solution Approach 1:
The patent applies preliminary action by selecting and propagating a mutant that has already developed the early flowering trait before commercial propagation. The mutant plant's buds are induced to flower under controlled conditions, and once the early flowering trait is confirmed, extensive propagation is performed to multiply this improved trait across many plants.
3Adaptability or versatility
If a natural mutant is selected for lighter pink flowers, then flower color variation is achieved, but the mutation must be stable through successive generations
Solution Approach 1:
The patent applies self-service by using asexual propagation methods (cuttings) that allow the mutant plant to reproduce itself, preserving its unique traits without requiring external intervention for trait stabilization. The mutant's own propagules automatically inherit and express the desired light pink color and early flowering traits, ensuring reliability through self-propagation.
