Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Soybean breeding is challenging due to the plant's self-pollinating nature, requiring extensive intervention by breeders to develop new germplasm with desired traits such as herbicide resistance, disease resistance, and altered oil profiles, which is unpredictable and time-consuming, involving complex genetic manipulation and extensive testing.

Innovation Solution

Development of the soybean cultivar WN1013170, which carries transgenes for herbicide resistance, disease resistance, and altered fatty acid profiles, utilizing techniques like marker-assisted selection and transformation to introduce specific genetic traits, enabling the production of seeds with improved yield and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional breeding methods are used to develop new soybean germplasm, then genetic diversity is maintained through self-pollination, but the breeding process becomes highly unpredictable and time-consuming

Engineering Contradiction:

Improvepredictability of breeding outcomeVSAvoidbreeding development time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical breeding methods (manual pollination manipulation, phenotypic selection) with molecular marker-based selection systems. Specific DNA markers are used to track desired traits through generations, enabling predictable selection without time-consuming phenotypic evaluation and significantly accelerating the breeding process while maintaining genetic diversity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If extensive genetic manipulation is performed to introduce desired traits, then new traits such as herbicide resistance and altered oil profiles are achieved, but the complexity of the breeding procedure increases

Engineering Contradiction:

Improvetrait diversityVSAvoidbreeding procedure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent substitutes complex phenotypic screening and multiple backcrossing procedures with a streamlined molecular marker-assisted selection system. DNA markers directly associated with target traits (herbicide resistance, oil profile modification) enable single-step selection, dramatically reducing procedural complexity while introducing diverse genetic traits into the soybean germplasm.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If marker-assisted breeding is employed to move specific genes, then breeding precision is improved, but the requirement for specialized knowledge and techniques increases

Engineering Contradiction:

Improveallele movement precisionVSAvoidbreeding technique accessibility

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent extracts and utilizes only the essential molecular marker-trait associations needed for breeding, separating the complex genomic information into specific, actionable marker systems. This extraction approach maintains high breeding precision for target traits while simplifying the technical requirements to manageable levels, making the methodology accessible to breeding programs with moderate molecular biology capabilities.
