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 XB16R11, which is the result of careful breeding and selection, combining traits such as resistance to aerial web blight, aphid antibiosis, brown stem rot, and improved fatty acid composition, through a comprehensive breeding program involving cross-pollination and genetic marker-assisted selection.

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 select plants with desired traits based on marker presence rather than waiting for phenotypic expression after multiple generations of breeding and selection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical breeding methods (relying on phenotypic selection and multiple generations of crossing) with a molecular-based selection system. By using molecular markers to identify and select plants with desired traits, the process eliminates the need for lengthy phenotypic evaluation and multiple breeding cycles, significantly reducing the time required to develop new varieties.

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 comprehensive trait improvement can be achieved, but the process becomes resource-intensive

Engineering Contradiction:
Improvecomprehensive trait improvementVSAvoidbreeding resources required
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent replaces resource-intensive traditional breeding operations (multiple generations of crossing, phenotypic screening, and manual selection) with a molecular marker-based selection system. This substitution dramatically reduces the number of plants that need to be grown and evaluated, as well as the labor and time required for breeding operations, while still achieving comprehensive trait improvement.

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

Solution Approach 2:

The patent introduces molecular markers as intermediary elements that mediate between the desired traits and the breeding process. These markers serve as accessible proxies for the actual traits, allowing selection to be based on easy-to-detect molecular presence rather than requiring extensive phenotypic analysis and multiple breeding cycles, thereby reducing overall resource requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If conventional soybean breeding is used to develop high-yielding varieties with disease resistance and stress tolerance, then agronomic performance improves, but the breeding process lacks efficiency

Engineering Contradiction:
Improveagronomic performanceVSAvoidbreeding efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces inefficient conventional breeding practices with a molecular marker-guided selection system. This substitution enables rapid identification and selection of plants with desired agronomic traits such as disease resistance, stress tolerance, and high yield potential, significantly improving breeding efficiency while maintaining or enhancing the reliability of the resulting varieties.

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

Solution Approach 2:

The patent implements feedback mechanisms through molecular marker analysis that provides immediate information about the genetic makeup of selected plants. This feedback allows breeders to quickly adjust selection criteria and breeding directions based on actual genetic data, rather than waiting for phenotypic expression after multiple generations, thereby improving both breeding efficiency and the reliability of produced varieties.

Inventive Principle:
Principle #23Feedback
