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 the soybean variety XB09F10, which is the result of careful breeding and selection, combining traits like resistance to aerial blight, brown stem rot, and improved fatty acid composition, along with molecular marker-assisted breeding techniques to introduce new traits, such as herbicide resistance and altered fatty acid profiles.

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 extremely time-consuming (6-12 years)

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

Solution Approach 1:

The patent applies preliminary action by pre-establishing a molecular marker map and identifying candidate genes for desirable traits before the actual breeding process begins. This allows the breeding program to target specific genetic regions and accelerate the selection process, reducing the overall breeding cycle duration while maintaining comprehensive trait improvement.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based selection. By using DNA markers linked to desirable traits, the breeding process can identify and select plants with desired characteristics much faster than traditional visual or physiological assessment methods, significantly reducing the 6-12 year breeding cycle.

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

2Adaptability or versatility

If multiple desirable traits are combined in a single variety through traditional breeding, then the variety achieves superior performance, but the process requires extensive resources and planning

Engineering Contradiction:
Improvecombination of desirable traitsVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the complex breeding program into distinct modular components: (1) molecular marker map construction, (2) candidate gene identification, (3) marker-assisted selection, and (4) variety development. This segmentation allows each component to be optimized independently and reduces overall program complexity while maintaining the ability to combine multiple desirable traits.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses molecular markers as intermediaries between the desired traits and the actual breeding process. These markers serve as detectable proxies for complex genetic traits, simplifying the selection process and reducing the resources needed to combine multiple desirable traits in a single variety.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If conventional breeding methods are used to introduce new traits into soybean varieties, then the variety can achieve trait diversity, but the process is resource-intensive and time-consuming

Engineering Contradiction:
Improvetrait diversityVSAvoidbreeding efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent replaces conventional phenotypic screening methods with molecular marker-based identification. This substitution allows rapid detection and selection of plants carrying desired traits, dramatically increasing breeding efficiency and reducing the resources required to introduce new traits into soybean varieties.

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

Solution Approach 2:

The patent uses molecular markers as genetic copies or proxies for the actual traits of interest. By selecting based on marker presence rather than direct phenotypic observation, the breeding process becomes much faster and more efficient, enabling rapid introduction of new traits while maintaining accuracy.

Inventive Principle:
Principle #26Copying
