Duessporaur Impatiens Cultivar Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new and distinct cultivars of New Guinea Impatiens plants with attractive flowers and good garden performance, as existing varieties may lack uniformity and desirable traits such as compact growth, specific leaf and flower colors, and robust flowering habits.
Innovation Solution
A new cultivar, 'DUESSPORAUR', resulting from a planned breeding program, exhibits an upright, spreading habit, vigorous growth, medium green leaves, early and frequent flowering, and dark orange flowers, distinguishing it from other Impatiens×hybrida varieties like 'Misato FG3' and 'SAKIMP012' with differences in compactness, leaf color, and flower color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Impatiens varieties are used, then they have basic flowering capability, but they lack uniformity and desirable traits such as compact growth, specific leaf and flower colors, and robust flowering habits
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic traits in the Impatiens×hybrida cultivar 'Duessporaur' to achieve uniform expression of compact growth habit, medium green leaf color, and dark orange flower color. This natural mutation was identified and propagated to create consistent phenotypic expression across the cultivar population, resolving the contradiction between adaptability and uniformity.
2Shape
If Impatiens×hybrida 'Misato FG3' is used, then it has magenta-colored flowers and darker green leaves, but it is less compact and has different flowering characteristics
Solution Approach 1:
The patent applies local quality by distinguishing specific phenotypic traits of 'Duessporaur' from other cultivars. The cultivar exhibits medium green leaf color (distinguishing from darker green of 'Misato FG3') and dark orange flower color (distinguishing from magenta of 'Misato FG3'), while simultaneously achieving superior compactness. This localized differentiation of traits resolves the contradiction between compactness and color intensity.
3Shape
If Impatiens×hybrida 'SAKIMP012' is used, then it has red purple-colored flowers and darker green leaves, but it is less compact and has different growth characteristics
Solution Approach 1:
The patent applies parameter changes by establishing distinct phenotypic parameters for 'Duessporaur' including compact growth habit, medium green leaf color, and dark orange flower color. The cultivar demonstrates early and freely flowering characteristics that differ from 'SAKIMP012', achieving a balance between compactness and flowering duration through stabilized genetic expression of these parameters.
