Solution Overview

Problem

Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to significant research costs and variability in resulting soybean varieties.

Innovation Solution

The development of the soybean variety A1036554, which incorporates specific genetic traits through crossing and backcrossing techniques, including the introduction of transgenic genes for herbicide resistance and improved oil quality, along with advanced breeding methods like genetic marker-assisted selection, to produce soybean plants with consistent and enhanced agronomic characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional breeding techniques are used, then soybean varieties can be developed with desirable traits, but the process is time-consuming and unpredictable

Engineering Contradiction:
Improvepredictability of breeding resultsVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs molecular marker-assisted selection that provides feedback on the genetic composition of breeding lines at the DNA level. This allows breeders to track the inheritance of desirable traits through generations and make informed selection decisions, significantly improving predictability and reducing the time required to develop stable varieties compared to traditional phenotypic selection methods.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces conventional mechanical/phenotypic breeding methods with molecular biology techniques. Instead of relying on observable traits and manual selection, the invention uses DNA-based molecular markers to identify and select plants with desired genetic characteristics, thereby accelerating the breeding process and improving reliability.

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

2Reliability

If conventional breeding techniques are used, then soybean varieties can be developed, but research costs are significant

Engineering Contradiction:
Improvestability of variety traitsVSAvoidresearch costs
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

Molecular marker-assisted selection provides early-generation feedback on genetic composition, allowing breeders to identify promising lines before investing extensive resources in field trials and multi-location testing. This feedback mechanism reduces the number of lines that need to be advanced through costly breeding stages, thereby reducing overall research costs while maintaining trait stability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent performs preliminary genetic analysis using molecular markers at early breeding stages to identify lines with desired traits before committing to expensive multi-year field testing. This preliminary action filters out unlikely candidates early, reducing the total research investment required to develop stable varieties.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If transgenic genes are introduced for herbicide resistance and improved oil quality, then agronomic characteristics are enhanced, but breeding complexity increases

Engineering Contradiction:
Improveagronomic performanceVSAvoidbreeding process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent uses molecular markers linked to transgenic traits to provide feedback on the presence and inheritance of herbicide resistance and improved oil quality genes. This allows breeders to track multiple complex traits simultaneously through DNA analysis rather than through complex phenotypic screening, simplifying the management of breeding processes involving transgenic modifications.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces complex phenotypic screening and manual tracking of transgenic traits with molecular marker-based detection. This substitution simplifies the breeding process by using DNA-level analysis to monitor the inheritance of multiple transgenic characteristics, reducing the complexity associated with managing herbicide resistance and oil quality improvements.

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