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, while existing methods face challenges in efficiently combining these traits in a single variety.

Innovation Solution

The development of a novel soybean variety, XB02W13, 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 comprehensive breeding program that includes backcrossing and genetic marker-assisted breeding to introduce desired traits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine multiple desirable traits, then the variety achieves stability and uniformity, but the breeding process becomes time-consuming and resource-intensive

Engineering Contradiction:
Improvetrait stabilityVSAvoidbreeding duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs molecular marker technology to provide real-time feedback on the presence and combination of desired traits during the breeding process. This allows breeders to select plants with the correct trait combinations much earlier than traditional phenotypic selection, significantly reducing breeding time while maintaining trait stability and uniformity in the final variety.

Inventive Principle:
Principle #23Feedback

2Productivity

If multiple desirable traits are combined in a single variety, then the agronomic performance is improved, but the breeding complexity increases

Engineering Contradiction:
Improvegrain yieldVSAvoidbreeding program complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the complex task of combining multiple traits into manageable segments by using specific molecular markers for each desired trait (disease resistance, yield components, quality traits). This segmentation allows breeders to track and combine individual traits systematically through marker-assisted selection, reducing overall breeding program complexity while achieving high grain yield with multiple desirable traits.

Inventive Principle:
Principle #1Segmentation

3Reliability

If extensive breeding and selection is performed to achieve superior varieties, then the disease resistance and yield are improved, but the resource consumption increases

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding resource consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent performs preliminary action by using molecular marker screening to identify and select plants carrying desired disease resistance genes early in the breeding process, before field testing. This preliminary genetic screening prevents the propagation of unwanted trait combinations and reduces the number of plants that need to be grown and evaluated in field trials, thereby reducing resource consumption while maintaining or improving disease resistance.

Inventive Principle:
Principle #10Preliminary action
