Solution Overview

Problem

The development of new soybean varieties is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as high yield, disease resistance, and environmental tolerance, while existing methods are inefficient and directionally unstable, taking six to twelve years from the first cross to delivering finished seed to farmers.

Innovation Solution

The introduction of the novel soybean variety 5PTMG32, which is stable and high-yielding, with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to produce plants and plant parts with improved agronomic characteristics, including resistance to diseases and environmental stresses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine desirable traits, then the variety achieves high yield and disease resistance, but the development process takes six to twelve years and requires extensive resources

Engineering Contradiction:
Improveyield stability and disease resistanceVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-screening and selecting parent lines with desired traits (high yield, disease resistance, environmental tolerance) before initiating the breeding program. This advance preparation of germplasm with known desirable characteristics reduces the time required for trait combination and validation in later breeding stages.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms through systematic evaluation and selection processes at multiple breeding stages. Performance data from field trials and genetic analysis are used to guide subsequent crossing decisions and selection criteria, enabling more efficient progression toward the target variety with desired traits.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If multiple crossing and selection steps are performed to achieve stable high-yielding varieties, then the variety shows uniformity and stability, but the process becomes complex and resource-intensive

Engineering Contradiction:
Improvevariety uniformity and trait stabilityVSAvoidbreeding process complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding process into distinct stages with specific objectives: parent line selection, controlled crossing, F1 generation evaluation, backcrossing if needed, and final variety testing. This structured segmentation allows each stage to be optimized independently while maintaining overall process efficiency and reducing unnecessary complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes parameter changes in the form of selective breeding parameters (crossing schemes, selection criteria, generation advancement timing) to achieve stable uniform varieties. By adjusting these breeding parameters based on performance data, the process efficiently progresses toward genetic stabilization without requiring excessive generations or complex interventions.

Inventive Principle:
Principle #35Parameter changes
