Mandevilla Cultivar Breeding for Compact Habit and Flower Shape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Mandevilla plant cultivars with fragrant flowers that offer distinct characteristics such as compact and vining habits, vigorous growth, glossy dark green leaves, and specific flower shapes and colors, which existing Mandevilla hybrida cultivars do not adequately provide.
Innovation Solution
The development of the Mandevilla hybrida cultivar 'Lanmissouri' through controlled cross-pollination between a proprietary selection of Mandevilla hybrida and 'Sunparapibra', resulting in plants with larger star-shaped light red purple flowers, compact vining habit, and enhanced branching, which are stable and reproduce true to type via asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If cross-pollination between proprietary selection and 'Sunparapibra' is conducted, then larger star-shaped light red purple flowers are produced, but the plant habit becomes less compact
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific flower characteristics (star-shaped, light red purple color, larger size) while controlling plant habit parameters through controlled cross-pollination and selection processes, achieving the desired floral traits without excessive growth
2Productivity
If vigorous growth habit is developed, then productivity is improved, but disease resistance may be compromised
Solution Approach 1:
The patent applies local quality by developing a compact vining habit with specific growth characteristics that are localized to the plant's structural features, allowing vigorous growth in controlled areas while maintaining overall compactness and disease resistance through selective breeding
3Shape
If larger flowers are produced, then aesthetic quality is improved, but the plant requires more space
Solution Approach 1:
The patent applies parameter changes by breeding for larger flower size while controlling the plant's spatial requirements through compact vining habit development, achieving enhanced floral aesthetics without proportionally increasing the space the plant occupies
