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, with limited control over genetic combinations and environmental factors.

Innovation Solution

The development of the soybean variety XR39V15X, which incorporates specific genetic loci for traits like herbicide resistance, disease resistance, and improved nutritional quality through genetic transformation and backcrossing, allowing for the creation of stable and uniform soybean plants with enhanced agronomic characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional breeding techniques are used to develop soybean varieties, then genetic diversity is maintained, but the breeding process is time-consuming and unpredictable with limited control over genetic combinations

Engineering Contradiction:
Improvepredictability of breeding outcomeVSAvoidbreeding duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by using molecular marker technology to pre-identify and select parent lines with desired traits before actual crossing. This allows breeders to predict offspring characteristics in advance, reducing the time needed for multiple generations of testing and selection while improving reliability of breeding outcomes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms through molecular marker-assisted selection, where DNA markers provide real-time information about genetic composition during the breeding process. This feedback allows for precise selection of plants with desired traits, accelerating the breeding process and improving predictability without losing genetic diversity.

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If conventional breeding techniques are used, then natural genetic variation is preserved, but control over specific genetic traits is limited

Engineering Contradiction:
Improvecontrol over genetic traitsVSAvoidbreeding method complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent uses molecular markers as intermediaries between phenotypic observation and genotypic selection. These markers serve as reliable indicators of desired traits, allowing breeders to control specific genetic characteristics with high precision while maintaining a relatively simple breeding workflow that doesn't require complex genetic manipulation techniques.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If traditional breeding methods are employed, then environmental adaptability is tested naturally, but yield stability across environments is difficult to achieve

Engineering Contradiction:
Improveyield stabilityVSAvoidbreeding efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent applies preliminary action by using molecular markers to pre-identify genetic combinations associated with yield stability before environmental testing. This allows breeders to focus resources on evaluating a smaller number of highly promising candidates across multiple environments, improving both yield stability and breeding efficiency simultaneously.

Inventive Principle:
Principle #10Preliminary action
