Solution Overview

Problem

Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved fatty acid profiles, but face challenges in efficiently combining these traits in a single variety.

Innovation Solution

The development of a novel soybean variety, XBP22005, which is the result of careful breeding and selection, combining traits like resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, through a process involving backcrossing and genetic marker-assisted breeding to introduce desired traits and achieve phenotypic stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional soybean breeding methods are used to develop new varieties with multiple desirable traits, then the variety can achieve comprehensive trait improvement, but the breeding process becomes time-consuming and resource-intensive

Engineering Contradiction:
Improvecomprehensive trait improvementVSAvoidbreeding process duration
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-establishing a set of molecular markers that are linked to desirable traits before the actual breeding process begins. These markers serve as predictive indicators, allowing breeders to identify and select plants with desired traits based on marker presence rather than waiting for phenotypic expression after multiple generations of breeding.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the traditional mechanical/phenotypic selection process with a molecular-based selection system. Instead of relying on visual inspection and multi-generational breeding to identify desirable traits, the invention uses molecular markers to detect and select for specific genetic configurations, significantly accelerating the breeding timeline and reducing resource requirements.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If traditional breeding methods are used to combine multiple desirable traits in a single variety, then trait combination is achieved, but the process requires precise planning and efficient resource use with minimal changes in direction

Engineering Contradiction:
Improvetrait combination capabilityVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces molecular markers as intermediary elements that mediate between the desired traits and the breeding process. These markers act as proxies or indicators that simplify the complex task of tracking multiple traits simultaneously, providing a straightforward molecular basis for selection that reduces the complexity of breeding program management.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the fundamental parameter of trait detection from phenotypic observation to molecular detection. By shifting the selection criterion from physical trait expression (which requires complex multi-generational tracking) to molecular marker presence (which can be detected in a single generation), the invention simplifies the breeding program structure while maintaining comprehensive trait combination capability.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If conventional soybean breeding is used to develop high-yielding varieties with stable traits, then agronomic soundness is achieved, but the development process takes six to twelve years from first cross to finished seed

Engineering Contradiction:
Improvevariety stabilityVSAvoidbreeding cycle length
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent applies preliminary action by pre-identifying and pre-characterizing molecular markers associated with stable, desirable traits before initiating the breeding process. This allows the breeding program to skip the lengthy phenotypic evaluation phase and directly select for plants carrying the desired genetic markers, significantly reducing the time to develop stable, high-yielding varieties.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent substitutes the traditional multi-generational phenotypic selection process with a molecular marker-based selection system. This replacement allows for rapid identification and fixation of stable traits without requiring six to twelve years of breeding cycles, while still achieving the same level of variety stability and agronomic soundness.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
