Solution Overview

Problem

Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits like disease resistance, drought tolerance, and improved fatty acid profiles, but few varieties achieve commercial success due to stringent selection criteria and long development times.

Innovation Solution

The development of the soybean variety XB38Y09, which combines traits such as glyphosate resistance, strong SCN race 3 resistance, good Phytophthora field tolerance, and sudden death syndrome tolerance, achieved through careful breeding and selection, allowing for efficient production and distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding processes are used to develop varieties with multiple desirable traits, then disease resistance and yield potential are improved, but the breeding time and resource requirements increase significantly

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

Solution Approach 1:

The patent applies preliminary action by pre-selecting parental lines with known desirable traits (glyphosate resistance, SCN resistance, Phytophthora tolerance) before crossing. This advance preparation of parental germplasm with characterized traits reduces the time needed for trait discovery and validation in later breeding stages, directly addressing the time-loss contradiction

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If stringent selection criteria are applied to ensure variety quality, then commercial success and trait stability are improved, but the number of varieties achieving commercial use decreases

Engineering Contradiction:
Improvevariety qualityVSAvoidcommercial variety output
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent employs feedback mechanisms through multi-environment field trials and performance evaluation of candidate varieties. This systematic feedback loop allows for objective assessment of trait stability and yield performance, enabling breeders to make informed decisions that maintain high quality standards while efficiently identifying commercial-ready varieties, thus resolving the contradiction between quality precision and productivity

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If multiple desirable traits are combined in a single variety, then agronomic performance and market value are improved, but the breeding complexity and resource requirements increase

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

Solution Approach 1:

The patent applies segmentation by dividing the breeding process into distinct stages: selection of parental lines with specific traits, controlled crossing to combine traits, and systematic evaluation of progeny. This segmented approach to multi-trait breeding reduces overall complexity by managing trait combination in organized steps rather than attempting simultaneous development, directly addressing the contradiction between adaptability and process complexity

Inventive Principle:
Principle #1Segmentation
