Mandevilla MOGI THREE Breeding for Vigor and Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Mandevilla varieties with vigorous plant habits suitable for commercial production that exhibit unique characteristics such as light pink flowers, rapid growth, dense branching, and abundant flowering, which are not adequately met by existing varieties.
Innovation Solution
The cultivar 'MOGI THREE' is developed through cross-pollination, characterized by light pink flowers, vigorous plants, rapid growth, short internodes, abundant flowering, and dense branching, making it suitable for trellis production or hanging baskets, with stable propagation through terminal vegetative cuttings and tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing Mandevilla varieties are used for commercial production, then basic flowering is achieved, but plant vigor, density, and flowering abundance are insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific genetic traits that modify plant vigor, internode length, and flowering abundance. The cross between seed parent S-1 and pollen parent S-2 resulted in offspring with optimized parameters including reduced internode length (increasing density) and enhanced flowering capacity, directly resolving the contradiction between productivity and reliability.
Solution Approach 2:
The breeding program segmented the parent plants with distinct characteristics (seed parent with dense branching, pollen parent with vigorous growth) and combined their traits in the offspring. This segmentation of desirable traits from different parents allowed the new variety to achieve both high vigor and abundant flowering simultaneously.
2Productivity
If Mandevilla varieties with vigorous growth are developed, then plant vigor and rapid growth are improved, but flower color intensity may be reduced
Solution Approach 1:
The patent successfully changed multiple parameters simultaneously through selective breeding. The new variety exhibits both rapid growth (increased productivity) and light pink flower color (modified illumination characteristic). This resolves the apparent contradiction by demonstrating that vigor and flower color can be independently optimized through genetic selection rather than being trade-offs.
3Quantity of substance
If dense branching is achieved through breeding, then plant density and flowering abundance improve, but plant height may be reduced
Solution Approach 1:
The patent applies parameter changes by specifically selecting for reduced internode length while maintaining overall plant vigor. The new variety has shorter internodes resulting in denser branching and more compact habit, which increases the quantity of branches and flowers without necessarily reducing total plant height when grown in commercial containers. This resolves the contradiction between branch density and plant height by optimizing the distribution of growth rather than simply reducing overall size.
