Solution Overview

Problem

Current soybean breeding methods face challenges in developing stable, high-yielding soybean varieties that combine desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, while existing technologies struggle to predict the genetic outcomes of breeding processes due to environmental and genetic variability.

Innovation Solution

The development of the soybean variety A1025962, which includes methods for crossing and breeding to combine traits like herbicide resistance, disease resistance, and improved nutritional quality, using techniques such as backcrossing and genetic transformation to introduce desired loci while maintaining the variety's morphological and physiological characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional breeding methods are used to combine desirable traits, then genetic diversity is increased, but the unpredictability of breeding outcomes increases

Engineering Contradiction:
Improvegenetic diversityVSAvoidbreeding outcome predictability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent employs marker-assisted selection where DNA markers are used to track and select for specific traits during breeding. This feedback mechanism allows breeders to predictably select plants with desired traits while maintaining genetic diversity, resolving the contradiction between genetic diversity and breeding outcome predictability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional phenotypic selection (mechanical/physical observation of traits) with molecular marker-based genotypic selection. This substitution enables precise tracking of genetic traits, making breeding outcomes predictable while preserving genetic diversity through controlled selection.

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

2Adaptability or versatility

If multiple desirable traits are combined in a single variety, then agronomic quality is improved, but the complexity of the breeding program increases

Engineering Contradiction:
Improveagronomic qualityVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the breeding program into distinct segments: initial cross-breeding to combine traits, followed by marker-assisted selection to individually track and select for each desired trait. This segmentation reduces overall program complexity by breaking down the complex task of combining multiple traits into manageable, systematic steps.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent develops universal DNA markers that can simultaneously track multiple different traits (herbicide resistance, disease resistance, maturity, yield). This multi-functionality allows a single breeding program to combine multiple desirable traits while managing complexity through a unified selection system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If genetic transformation is used to introduce desired loci, then breeding precision is improved, but the device complexity increases

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

Solution Approach 1:

The patent uses DNA markers as intermediaries between the desired traits and the selection process. These markers serve as detectable proxies for complex genetic traits, enabling precise selection without requiring direct manipulation or observation of the complex transformation processes themselves, thus reducing perceived complexity while maintaining precision.

Inventive Principle:
Principle #24Intermediary (Mediator)
