Solution Overview

Problem

There is a need for a new cultivar of New Guinea Impatiens that combines a beautiful deep rose flower color, strong root system, and compact growth habit, which existing cultivars have not effectively addressed.

Innovation Solution

The development of the Impatiens×hybrida cultivar 'SAKIMP017' through interspecific hybridization between 'NC-177' and 'NC-229B', resulting in a plant with deep rose flowers, compact growth habit, and strong root system, achieved through vegetative propagation and evaluation for stability in successive generations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing Impatiens cultivars are used, then they have established growth habits and flower colors, but they do not simultaneously exhibit the desired combination of deep rose flower color, compact growth habit, and strong root system

Engineering Contradiction:

Improveflower color consistencyVSAvoidgrowth habit variation

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines traits from two different parent lines: 'NC-177' (providing compact growth habit and strong root system) and 'NC-229B' (providing deep rose flower color). Through controlled hybridization, these distinct parental traits are merged into a single cultivar 'SAKIMP017' that expresses all desired characteristics simultaneously, resolving the contradiction between flower color consistency and growth habit adaptability.

Inventive Principle:

Principle #5Merging (Combining)

2Stability of the object's composition

If vegetative propagation is used to reproduce the cultivar, then the deep rose flower color and compact growth habit are maintained true to type, but the root system strength must be evaluated across multiple generations to ensure stability

Engineering Contradiction:

Improvetrait stabilityVSAvoidevaluation time

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent performs preliminary evaluation of the root system strength during the initial development and selection phases before widespread propagation. By assessing root characteristics in the F1 generation and selected plants during controlled trials, the breeders establish trait stability early, reducing the need for extensive multi-generational evaluation and thereby minimizing time loss while ensuring compositional stability.
