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, taking six to twelve years from the first cross to delivering finished seed.

Innovation Solution

The introduction of soybean variety 5PKPU92, 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 variety development methods are used, then desirable traits such as high yield and disease resistance can be combined, but the process takes six to twelve years and is time-consuming

Engineering Contradiction:
Improvecombination of desirable traitsVSAvoiddevelopment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-establishing a diverse germplasm collection with known desirable traits before the actual breeding process. This preparatory step allows breeders to quickly identify and combine specific traits without starting from scratch, thereby reducing the overall development time while maintaining trait combination reliability

Inventive Principle:
Principle #10Preliminary action

2Reliability

If traditional breeding processes are followed, then new varieties can be developed with improved traits, but the process requires extensive resources and precise planning

Engineering Contradiction:
Improveagronomic soundnessVSAvoidbreeding process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the breeding process into distinct phases: germplasm collection, trait identification, cross-breeding, and evaluation. This segmentation allows each stage to be managed independently with specific protocols, reducing overall process complexity while maintaining agronomic soundness through systematic progression

Inventive Principle:
Principle #1Segmentation

3Reliability

If multiple crossing and selection steps are performed to achieve high yield and stability, then desirable variety characteristics can be obtained, but the directionality and efficiency of the process are reduced

Engineering Contradiction:
Improveyield stabilityVSAvoidbreeding efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements feedback mechanisms through systematic evaluation and characterization of breeding lines at each generation. Performance data on yield, stability, and other traits are collected and used to guide subsequent crossing decisions, ensuring the breeding process remains directional and efficient while achieving reliable variety characteristics

Inventive Principle:
Principle #23Feedback
