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 the complexity of combining these traits effectively.

Innovation Solution

The development of the soybean variety XB48E09, which combines traits such as glyphosate resistance, strong SCN race 3 resistance, good Phytophthora field tolerance, and excellent sudden death syndrome tolerance, achieved through careful breeding and selection, allowing for improved yield potential and stability across various environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding processes are used to develop new varieties, then desirable traits can be combined, but the process is time-consuming and resource-intensive

Engineering Contradiction:
Improvedesirable traits combinationVSAvoidbreeding process duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-establishing a structured breeding program with defined objectives, selecting parent germplasm with desired traits before the actual crossing, and planning multiple generations of selection and evaluation in advance. This systematic preparation and forward planning reduces the overall time and resource requirements while maintaining the reliability of combining desirable traits.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If multiple desirable traits are combined in a single variety, then agricultural performance improves, but the complexity of achieving this increases

Engineering Contradiction:
Improveagricultural performanceVSAvoidbreeding program complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the breeding program into distinct phases and components: selecting parent germplasm with specific traits, performing controlled crosses, evaluating progeny for multiple traits, selecting superior lines, and validating performance across environments. This segmentation makes the complex process of combining multiple desirable traits more manageable and systematic.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The breeding program is designed to simultaneously achieve multiple objectives including disease resistance, yield improvement, and trait stability across different environments. By creating a universal breeding framework that addresses multiple needs simultaneously, the complexity is managed through integrated planning rather than separate specialized programs.

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

3Reliability

If new soybean varieties are developed through extensive breeding, then trait improvement is achieved, but fewer varieties reach commercial success

Engineering Contradiction:
Improvetrait improvementVSAvoidcommercial variety output
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent incorporates feedback mechanisms through systematic evaluation of breeding progress, monitoring trait expression across generations, assessing performance in field trials, and using this information to adjust selection criteria and breeding directions. This feedback loop ensures that resources are allocated to varieties most likely to succeed commercially while maintaining high trait improvement reliability.

Inventive Principle:
Principle #23Feedback
