Solution Overview

Problem

Existing ornamental plant breeding methods struggle to consistently produce plants with novel characteristics such as color, growth habit, and hardiness in New Guinea Impatiens varieties, leading to unpredictable and costly research efforts.

Innovation Solution

The development of the New Guinea Impatiens variety SAKIMP075, which is derived from an interspecific hybridization between Impatiens 'NQK-2163C' and 'NMK-3108', and its use in breeding programs through techniques like pedigree breeding, backcrossing, mutation breeding, and gene editing using CRISPR/Cas9, TALENs, and ZFNs to introduce desired traits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional ornamental plant breeding methods are used for New Guinea Impatiens, then breeding programs can be conducted, but the production of plants with novel characteristics (color, growth habit, hardiness) is unpredictable and costly

Engineering Contradiction:
Improvepredictability of producing plants with novel characteristicsVSAvoidbreeding program duration and cost
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by creating a stable interspecific hybrid variety (SAKIMP075) through controlled cross-pollination of Impatiens 'NQK-2163C' and 'NMK-3108' before use in breeding programs. This pre-established hybrid serves as a reliable starting point that exhibits uniformity and stability, allowing breeders to predictably produce plants with novel characteristics without the uncertainty of traditional breeding methods.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by utilizing the genetic parameters of interspecific hybridization to create a new variety with stabilized traits. By changing the genetic composition through controlled cross-pollination and selecting for uniformity and stability, the breeding process transforms unpredictable trait expression into reliable, consistent characteristics that can be replicated.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If interspecific hybridization is used to create new varieties, then novel characteristics can be achieved, but the complexity of breeding programs increases

Engineering Contradiction:
Improvenovel characteristics (color, growth habit, hardiness)VSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding program into distinct phases: first creating the interspecific hybrid (SAKIMP075) through controlled cross-pollination, then using this stable hybrid as a separate resource for subsequent breeding work. This segmentation allows the complex interspecific hybridization to be isolated as a one-time event, while subsequent breeding programs can leverage the stabilized traits of SAKIMP075 with reduced complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses an intermediary approach by establishing SAKIMP075 as a mediator variety that bridges different Impatiens lines. This stable interspecific hybrid serves as an intermediate resource that combines desirable traits from its parents while providing uniformity and stability, thereby simplifying subsequent breeding programs that use SAKIMP075 as a parent line.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple breeding techniques (pedigree breeding, backcrossing, mutation breeding, gene editing) are applied, then desired traits can be introduced, but the complexity and cost of research efforts increase

Engineering Contradiction:
Improvetrait improvement capabilityVSAvoidbreeding technique complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by first establishing the stable intersspecific hybrid SAKIMP075 through controlled cross-pollination before applying subsequent breeding techniques. This pre-established hybrid provides a uniform and stable genetic base that simplifies the application of pedigree breeding, backcrossing, mutation breeding, and gene editing techniques, as the starting material already exhibits the desired uniformity and stability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by leveraging the stabilized genetic parameters of SAKIMP075 to make subsequent breeding techniques more effective and less complex. The uniformity and stability of the hybrid variety provide a consistent genetic parameter base, allowing traits to be introduced through pedigree breeding, backcrossing, mutation breeding, and gene editing with greater predictability and reduced experimental complexity.

Inventive Principle:
Principle #35Parameter changes
