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 the soybean variety XBP37012, 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 crossing, backcrossing, and genetic marker-assisted breeding to ensure homozygosity and 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 process becomes time-consuming and resource-intensive

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 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 (repeated crossing and selection based on physical observation) with a molecular biology-based system. Molecular markers provide a rapid, objective means to identify and select plants with desired traits, eliminating the need for lengthy phenotypic evaluation cycles and reducing the time required to develop new varieties.

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

2Adaptability or versatility

If traditional soybean breeding methods are used to combine multiple desirable traits, then comprehensive trait improvement can be achieved, but resource consumption increases

Engineering Contradiction:
Improvecomprehensive trait improvementVSAvoidresource consumption
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent replaces resource-intensive traditional breeding operations (requiring large numbers of plants, multiple generations of crossing, and extensive field evaluations) with a molecular marker-based selection system. This substitution dramatically reduces the number of plants that need to be grown and evaluated, as markers provide direct information about trait presence without requiring extensive phenotypic data collection.

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

Solution Approach 2:

The patent uses molecular markers as copies or proxies for the actual desirable traits. Instead of directly observing and selecting for complex phenotypic traits that require extensive resources, the markers serve as convenient, easily detectable copies that indicate the presence of the desired traits, thereby reducing the resources needed for selection and evaluation.

Inventive Principle:
Principle #26Copying

3Productivity

If conventional breeding processes are used, then variety development can proceed, but the process lacks precision and efficiency

Engineering Contradiction:
Improvevariety development efficiencyVSAvoidbreeding process precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent replaces imprecise traditional breeding methods (relying on visual selection and manual crossing) with precise molecular marker-based techniques. Molecular markers provide objective, binary information (present/absent) that enables exact selection of plants with desired traits, eliminating the subjectivity and imprecision inherent in phenotypic selection and manual breeding operations.

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

Solution Approach 2:

The patent implements feedback mechanisms through molecular marker analysis, where the presence or absence of markers provides immediate information about trait inheritance. This feedback allows breeders to quickly adjust selection criteria and breeding strategies based on actual genetic data, improving both the precision and efficiency of the breeding process compared to traditional methods that rely on delayed phenotypic observation.

Inventive Principle:
Principle #23Feedback
