Solution Overview

Problem

Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to significant research costs and variability in results.

Innovation Solution

The development of the soybean variety 5PUWT62, which incorporates specific genetic traits through crossing and backcrossing techniques, including the use of transgenic genes for herbicide resistance and dicamba tolerance, along with advanced breeding methods like genetic marker-assisted selection, to produce stable and high-yielding soybean plants with improved agronomic characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional breeding techniques are used, then soybean varieties can be developed with desirable traits, but the process is time-consuming and unpredictable

Engineering Contradiction:
Improvepredictability of breeding resultsVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces conventional mechanical breeding methods (manual crossing, selection, and evaluation) with molecular marker-assisted selection technology. This substitution enables identification of desirable traits at the DNA level, dramatically reducing the time required for breeding cycles and improving predictability of breeding outcomes by selecting plants based on genetic markers associated with target traits rather than waiting for phenotypic expression.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces molecular markers as intermediaries between the breeder and the target traits. These markers serve as proxies that indicate the presence of desirable genetic elements, allowing breeders to select plants with desired traits early in the breeding process without waiting for the traits to manifest phenotypically, thus accelerating the breeding process and improving reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If conventional breeding techniques are used, then soybean varieties can be developed, but research costs are significant

Engineering Contradiction:
Improvestability of variety traitsVSAvoidresearch costs
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent replaces resource-intensive conventional breeding procedures with cost-effective molecular marker analysis. By using DNA-based selection methods, the program reduces expenses associated with maintaining large breeding populations over multiple generations, field testing, and phenotypic evaluation, while simultaneously improving trait stability through precise genetic selection.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the selection parameter from phenotypic observation to genotypic analysis. This parameter change allows breeders to identify and select for desirable traits at the molecular level, reducing the need for expensive multi-year field trials and large-scale phenotypic evaluation, thereby lowering research costs while ensuring trait stability.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If transgenic genes are introduced for herbicide resistance, then agronomic quality is improved, but genetic complexity increases

Engineering Contradiction:
Improveherbicide resistanceVSAvoidgenetic structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses molecular markers as intermediaries to track and select for transgenic traits during backcrossing. This approach simplifies the management of genetic complexity by providing a straightforward method to identify plants that have successfully incorporated the desired transgenic genes while recovering the recurrent parent background, making the breeding process more manageable despite the increased genetic complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
