Solution Overview

Problem

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

Innovation Solution

The introduction of the novel soybean variety 5PSNR14, which incorporates genetic traits for resistance to diseases such as Aerial Web Blight, Anthracnose, Aphid Antibiosis, and Brown Stem Rot, along with improved agronomic characteristics, through a combination of breeding and genetic manipulation techniques.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional breeding methods are used to develop disease-resistant soybean varieties, then resistance to diseases is improved, but the development time becomes excessively long (6-12 years)

Engineering Contradiction:
Improvedisease resistanceVSAvoidvariety development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing parent lines with specific disease resistance traits (Aerial Web Blight, Anthracnose, Aphid Antibiosis, Brown Stem Rot) before crossing. This preliminary characterization of genetic traits in parent varieties allows for more efficient breeding by predicting progeny performance, thereby reducing the overall development time while maintaining reliable disease resistance

Inventive Principle:
Principle #10Preliminary action

2Reliability

If multiple disease resistance traits are incorporated into a single variety, then comprehensive disease resistance is improved, but the breeding program complexity increases

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

Solution Approach 1:

The patent merges multiple disease resistance traits (Aerial Web Blight, Anthracnose, Aphid Antibiosis, Brown Stem Rot) into a single soybean variety through controlled crossing programs. By systematically combining these resistance traits from different parent lines and evaluating progeny for all traits simultaneously, the patent achieves comprehensive disease resistance while managing breeding program complexity through structured selection protocols

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If extensive field testing is conducted to ensure yield stability across environments, then yield reliability is improved, but resource consumption increases

Engineering Contradiction:
Improveyield stabilityVSAvoidresource consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements feedback mechanisms by conducting multi-environment field trials and using the performance data to refine selection criteria and breeding decisions. The feedback from field testing results allows the breeding program to identify the most promising lines for further development, optimizing resource allocation by focusing efforts on varieties that demonstrate consistent performance across different environments rather than testing all lines equally

Inventive Principle:
Principle #23Feedback
