Solution Overview

Problem

The challenge in soybean breeding is to develop stable, high-yielding varieties that are resistant to diseases, insects, and abiotic stresses while maintaining desirable agronomic traits, which is a time-consuming process requiring precise planning and resource management.

Innovation Solution

The development of the soybean variety RJS40001, which exhibits resistance to Roundup herbicides, Soybean Cyst Nematode Race 3, Phytophthora, sudden death syndrome, and drought, with a valuable combination of traits including high yield potential, excellent harvest standability, and shattering resistance, achieved through careful breeding and selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to develop varieties with multiple desirable traits (disease resistance, insect resistance, stress tolerance, high yield), then the variety achieves improved agronomic performance, but the breeding process becomes extremely time-consuming (6-12 years)

Engineering Contradiction:
Improvevariety stability and performanceVSAvoidbreeding cycle duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing parental germplasm with specific desirable traits before crossing. The breeding program systematically identifies and evaluates parent lines for disease resistance, yield potential, and other target traits in advance, allowing the development process to proceed more efficiently with predetermined breeding objectives and selected parental combinations.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If extensive germplasm screening and selection is performed to achieve high yield potential and multiple resistances, then the variety quality improves, but the complexity of the breeding program increases

Engineering Contradiction:
Improvevariety performance and resistanceVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the complex breeding program into distinct phases and components: germplasm collection and characterization, parental selection based on specific criteria, controlled crossing operations, progeny evaluation for individual traits, and final variety registration. This systematic segmentation allows each aspect of the breeding process to be managed and optimized independently while contributing to the overall variety development.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple traits are combined in a single variety (disease resistance, insect resistance, stress tolerance, high yield), then the agronomic value increases, but the difficulty of achieving stable inheritance of all traits simultaneously increases

Engineering Contradiction:
Improvevariety multi-trait performanceVSAvoidtrait inheritance stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies merging by combining multiple desirable traits from different parental germplasm sources into a single integrated variety. The breeding program systematically crosses parent lines possessing different target traits (disease resistance, yield potential, stress tolerance) and selects progeny that inherit and stabilize the combination of these traits, creating a unified variety with multi-trait performance.

Inventive Principle:
Principle #5Merging (Combining)
