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 tolerance to environmental stresses, while existing methods are inefficient and directionally unstable.

Innovation Solution

The introduction of soybean variety 5PLSB92, which is stable and homozygous, combined with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to produce plants with improved agronomic characteristics and disease resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine desirable traits, then the variety can achieve high yield and disease resistance, but the development process takes 6-12 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-characterizing variety 5PLSB92 with multiple desirable traits (high yield, disease resistance, stress tolerance) before using it as a parent in breeding programs. This pre-prepared genetic foundation eliminates the need for time-consuming trait combination experiments, directly reducing the 6-12 year development timeline while maintaining reliability of desired traits

Inventive Principle:
Principle #10Preliminary action

2Productivity

If multiple crossing and selection steps are performed to achieve stable high-yielding varieties, then the variety shows maximal yield over different conditions, but the process requires precise planning and efficient resource use with minimum changes in direction

Engineering Contradiction:
Improveseed yieldVSAvoidbreeding process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by providing a variety (5PLSB92) with already-optimized genetic parameters for yield, disease resistance, and stress tolerance. Using this pre-optimized parent in crossing programs reduces the complexity of multiple selection steps needed to achieve stable high-yielding varieties, as the desirable trait combinations are already established in the parent variety
