Mandevilla Sunparamiho Cultivar Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Mandevilla plant cultivars with desirable traits such as vining and freely-branching habits, glossy leaves, and long flowering periods with white-colored flowers, which existing cultivars do not adequately provide.
Innovation Solution
A new Mandevilla cultivar, 'Sunparamiho', was developed through controlled cross-pollination of proprietary selections M7 and M1, exhibiting unique characteristics like vining habit, vigorous growth, glossy leaves, medium-sized white flowers, and extended flowering periods, which are stable through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Mandevilla cultivars are used, then basic flowering is achieved, but desirable traits such as vining habit, freely-branching structure, glossy leaves, and long flowering periods with white flowers are not adequately provided
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific phenotypic parameters including vining growth habit, freely-branching structure, glossy leaf texture, white flower color, and extended flowering duration. The cultivar 'Sunparamiho' exhibits these optimized parameters resulting from systematic breeding selections that modified multiple traits simultaneously to achieve the desired combination of adaptability and reliable flowering.
2Adaptability or versatility
If cross-pollination breeding is conducted to create new cultivars, then novel traits are generated, but breeding time and complexity increase
Solution Approach 1:
The patent employs preliminary action through controlled cross-pollination between specifically selected parent plants (M7 as female parent and M1 as male parent) to pre-establish the desired genetic combination before field testing. This planned breeding approach with predetermined parent selections accelerates the development of novel trait combinations by preparing the genetic foundation in advance rather than relying on random mutation or extended selection periods.
