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, due to the unpredictability of genetic combinations and environmental factors.

Innovation Solution

The development of the soybean variety A1037423, which combines desirable traits through a specific breeding history and genetic transformation, including a single locus conversion that can introduce traits like herbicide resistance, disease resistance, and improved nutritional quality, using methods like backcrossing and genetic transformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional breeding methods are used to develop soybean varieties, then genetic diversity is maintained, but the predictability of desirable trait combinations is low and development time is extended

Engineering Contradiction:
Improvepredictability of trait combinationsVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing genetic transformation to introduce specific desirable traits (herbicide resistance, disease resistance, nutritional quality) directly into the soybean variety A1037423 through controlled genetic modification, rather than relying on unpredictable conventional breeding. This preliminary genetic setup allows the variety to already possess target traits before field testing, significantly reducing the time and increasing the predictability of trait expression.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple breeding objectives are pursued simultaneously, then comprehensive improvement is achieved, but the complexity of the breeding program increases

Engineering Contradiction:
Improvecomprehensive trait improvementVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding objectives into distinct, independently addressable components: herbicide resistance (glyphosate tolerance), disease resistance (SCN, PRR, bacterial blight), and nutritional quality (protein and oil content). Each trait is targeted through specific genetic transformation events or selective breeding steps, allowing the complex breeding program to be managed as separate, manageable modules rather than an undifferentiated whole.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If genetic transformation is used to introduce specific traits, then breeding precision is improved, but the complexity of the transformation process increases

Engineering Contradiction:
Improvebreeding precisionVSAvoidtransformation process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies the intermediary principle by using Agrobacterium tumefaciens as a mediator to transfer desired genetic traits into the soybean variety A1037423. This bacterial intermediary carries the genetic material for herbicide resistance, disease resistance, and nutritional improvement, facilitating precise genetic modification without requiring direct human manipulation of the plant genome. The Agrobacterium acts as a natural vector that simplifies the transformation process while maintaining high precision in trait introduction.

Inventive Principle:
Principle #24Intermediary (Mediator)
