Mandevilla Cultivar MAN222902 Breeding for Vigor and Flower Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Mandevilla plant cultivars with large, attractive flowers and good container performance, as existing varieties may lack vigor, flower size, or color consistency under varying environmental conditions.
Innovation Solution
The development of Mandevilla sanderi 'MAN222902' through cross-pollination of Mandevilla sanderi 'Lannevada' and 'Rio Red' resulted in a cultivar with a vigorous growth habit, dark red flowers, smaller glossy leaves, and improved stem thickness, distinguishing it from parent varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing Mandevilla varieties are used, then they may have large flowers, but they lack vigor and show poor container performance
Solution Approach 1:
The patent combines the desirable traits of two parent varieties through controlled cross-pollination. The female parent 'Lannevada' contributes flower characteristics while the male parent 'Rio Red' contributes vigor and growth habits. The resulting cultivar 'MAN222902' merges these traits to achieve both large flowers and strong container performance, resolving the contradiction between flower size and vigor.
2Duration of action of stationary object
If existing Mandevilla varieties are used, then they may flower, but flower color consistency varies under different environmental conditions
Solution Approach 1:
The patent selects and stabilizes specific genetic parameters through controlled breeding to achieve color consistency. Cultivar 'MAN222902' was bred to maintain its dark red flower color (RHS color group 53A-53D) across varying environmental conditions, including different temperatures and light intensities. This genetic stabilization resolves the contradiction between flowering duration and color consistency.
3Quantity of substance
If Mandevilla sanderi 'Lannevada' is used as parent, then large flowers are obtained, but flower color is lighter red compared to the new cultivar
Solution Approach 1:
The patent applies local quality by introducing a specific genetic factor from the male parent 'Rio Red' that concentrates and intensifies the red pigment in the flower petals. While maintaining the large flower size from 'Lannevada', the new cultivar 'MAN222902' achieves darker, more intense red coloring (RHS 53A-53D versus lighter shades in parent), resolving the contradiction between flower size and color intensity.
