New Guinea Impatiens Cultivar SAKIMP014 Trait Combination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of New Guinea impatiens that combines desirable traits such as white flowers with a light pink tint, compact growth habit, and a strong root system, which are not adequately met by existing cultivars.
Innovation Solution
The development of the cultivar 'SAKIMP014' through interspecific hybridization between a white flowered Impatiens plant 'NG-01 WD' and a lilac flowered Impatiens plant 'EL-1A-2', resulting in a plant with white flowers, compact growth, and a robust root system, which is stable across generations of asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Impatiens cultivars are used, then they have established growth habits and flower production, but they do not simultaneously exhibit the combination of white flowers with light pink tint, compact growth habit, and strong root system
Solution Approach 1:
The patent combines multiple desirable traits from different parent lines through interspecific hybridization. The female parent 'NG-01 WD' contributes white flower color and compact growth habit, while the male parent 'EL-1A-2' contributes strong root system and disease resistance. The resulting cultivar 'SAKIMP014' merges these traits into a single stable genotype that reproduces true-to-type through asexual propagation, resolving the contradiction between trait combination and reliability.
2Adaptability or versatility
If hybridization is performed to create new trait combinations, then novel characteristics are achieved, but the stability of traits across generations may be compromised
Solution Approach 1:
The patent uses asexual propagation methods (cuttings, tissue culture) to create genetically identical copies of the hybrid plant. This ensures that the novel trait combination achieved through hybridization is precisely replicated in successive generations without segregation or recombination, maintaining both the novelty and stability of the cultivar's characteristics.
