Solution Overview

Problem

The development of stable, high-yielding soybean varieties that are resistant to diseases and abiotic stresses is a time-consuming process, requiring precise planning and resource optimization, with existing soybean varieties often lacking comprehensive resistance to multiple diseases and environmental stresses.

Innovation Solution

The development of the soybean variety BG4184Y, which combines improved traits such as disease resistance, drought tolerance, and enhanced agronomic characteristics through careful breeding and selection, including the introduction of transgenic or mutant traits, to create a stable and resilient soybean line.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to develop disease-resistant varieties, then disease resistance is improved, but the breeding process becomes time-consuming and resource-intensive

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding process duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting parental lines with known disease resistance traits and using marker-assisted selection to track desired resistance genes through generations. This allows breeders to anticipate and plan for resistance inheritance patterns, significantly reducing the time required to develop resistant varieties compared to traditional trial-and-error breeding approaches.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If multiple disease resistance traits are combined in a single variety, then comprehensive resistance is improved, but the breeding complexity increases

Engineering Contradiction:
Improvecomprehensive disease resistanceVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding program into distinct modules: selecting for resistance to specific diseases (e.g., cyst nematode, sudden death syndrome, brown stem rot) independently, then systematically combining these resistance traits. This modular approach allows breeders to manage complexity by handling one resistance trait at a time while using marker-assisted selection to track multiple traits simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies universality by developing a standardized breeding protocol using marker-assisted selection that can be applied across multiple disease resistance traits. The same molecular markers and selection procedures are used universally for different diseases, reducing the need for separate breeding programs for each disease and simplifying the overall process of combining multiple resistance traits.

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

3Stability of the object's composition

If extensive field testing is conducted to ensure variety stability, then trait uniformity is improved, but the time required for variety development increases

Engineering Contradiction:
Improvetrait uniformityVSAvoidtesting duration
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent applies mechanics substitution by replacing extensive phenotypic field testing with molecular marker-based genotypic analysis. Instead of growing and evaluating thousands of plants across multiple locations to assess trait uniformity, breeders use DNA markers to directly detect the presence and consistency of desired resistance genes, dramatically reducing testing time while maintaining or improving accuracy in assessing variety stability.

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