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, and often result in varieties that are not easily replicable.

Innovation Solution

The development of the soybean variety 5PDSD70, which is created through a specific breeding history involving cross-breeding, bulk selection, and molecular marker-assisted selection, incorporating traits like glyphosate and dicamba tolerance, and resistance to various diseases, and is suitable for propagation and hybrid production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional breeding techniques are used to develop soybean varieties, then desirable traits such as disease resistance and yield can be improved, but the breeding process becomes time-consuming and unpredictable

Engineering Contradiction:
Improvevariety stabilityVSAvoidbreeding time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs molecular marker-assisted selection which provides feedback on the genetic composition of breeding lines at the DNA level. This allows breeders to track inheritance of desired traits through specific molecular markers, enabling informed selection decisions that accelerate breeding while ensuring variety stability and replicability.

Inventive Principle:
Principle #23Feedback

2Reliability

If conventional breeding techniques are used, then trait improvement can be achieved, but the varieties produced are not easily replicable

Engineering Contradiction:
Improvevariety replicabilityVSAvoidbreeding efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces conventional phenotypic selection methods with molecular marker-assisted selection. Instead of relying on visual trait assessment and manual selection processes, the invention uses DNA-based molecular markers to identify and select plants with desired genetic compositions, thereby improving replicability and efficiency of variety production.

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

3Adaptability or versatility

If multiple desirable traits are combined in a single variety, then agronomic quality and yield can be improved, but the breeding complexity increases

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by breaking down the complex task of combining multiple traits into manageable units through the use of specific molecular markers for each trait. Each marker serves as an independent unit that can be tracked and selected separately, allowing systematic combination of multiple desirable traits while simplifying the overall breeding program through modular marker-based selection.

Inventive Principle:
Principle #1Segmentation
