Solution Overview

Problem

Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits like 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 the soybean variety XBP37004, which is the result of careful breeding and selection, combining traits such as resistance to aerial blight, brown stem rot, and improved fatty acid composition, along with molecular marker profiles for identification and introgression of new traits, facilitating efficient breeding and trait introduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine multiple desirable traits, then disease resistance and yield improvement can be achieved, but the breeding process becomes extremely time-consuming and resource-intensive

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding cycle duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Molecular markers serve as feedback mechanisms that provide direct information about the presence of desired traits during breeding, allowing breeders to make informed selection decisions without waiting for phenotypic expression. This accelerates the breeding cycle by enabling early selection of plants carrying disease resistance genes and other desirable traits.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based selection. Instead of visually assessing disease resistance or waiting for trait expression, breeders use DNA markers to directly detect the presence of desired genetic traits, fundamentally changing the selection mechanism from phenotypic to genotypic assessment.

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

2Reliability

If multiple disease resistance traits are combined in a single variety through conventional breeding, then comprehensive protection is achieved, but the complexity of the breeding program increases significantly

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

Solution Approach 1:

The breeding program is segmented into distinct molecular marker-assisted selection steps for different traits. Each disease resistance trait can be tracked and selected for independently using specific molecular markers, allowing breeders to systematically combine multiple traits without being overwhelmed by program complexity. The segmentation of selection criteria into marker-based modules simplifies management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Molecular markers serve multiple functions simultaneously: they identify disease resistance genes, track inheritance patterns, predict trait expression, and enable early selection. This multi-functionality reduces the need for separate breeding programs for different traits and simplifies the overall breeding strategy while achieving comprehensive disease resistance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If extensive breeding and selection processes are undertaken to develop new varieties, then improved yield and trait combination are achieved, but resource consumption increases

Engineering Contradiction:
Improveseed yieldVSAvoidresource consumption
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

Molecular marker analysis is performed at early seedling stages to identify plants carrying desired traits before significant resource investment in growing and maturing those plants. This preliminary genetic screening prevents wasted resources on plants that will not express desired traits, allowing breeders to focus resources only on promising candidates with high potential for improved yield and disease resistance.

Inventive Principle:
Principle #10Preliminary action
