Solution Overview

Problem

Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, herbicide tolerance, and improved nutritional quality, as they rely on conventional breeding procedures that are time-consuming and unpredictable, with limited control over genetic combinations.

Innovation Solution

The development of the soybean variety A1024755, which includes methods for crossing and breeding to introduce specific traits like herbicide resistance, disease resistance, and improved nutritional quality through genetic transformation and backcrossing, allowing for the creation of hybrid seeds and plants with consistent physiological and morphological characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

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

Engineering Contradiction:
Improvepredictability of trait inheritanceVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent uses molecular markers as intermediaries to detect and track specific genes or QTLs associated with desirable traits during breeding. These markers serve as proxies that allow breeders to identify plants carrying target traits without waiting for phenotypic expression, thereby accelerating selection and improving predictability of trait inheritance in the resulting soybean varieties.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based selection. Instead of relying on observable physical traits that require plant growth and environmental expression, the invention uses DNA-level detection to identify desired genetic combinations early in the breeding process, substituting biochemical analysis for conventional phenotypic evaluation.

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

2Adaptability or versatility

If conventional breeding procedures are used, then soybean varieties can be developed, but control over genetic combinations is limited

Engineering Contradiction:
Improvecontrol over genetic combinationsVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements feedback through molecular marker detection at multiple stages of the breeding process. By continuously monitoring the presence and combination of target genes/QTLs using markers, breeders can make informed decisions about which plants to advance, cross, or discard, thereby exercising precise control over genetic combinations while managing breeding program complexity through data-driven selection.

Inventive Principle:
Principle #23Feedback

3Reliability

If multiple desirable traits are combined in a single variety, then agronomic quality improves, but breeding difficulty increases

Engineering Contradiction:
Improvestability of desirable traitsVSAvoidbreeding process simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent segments the complex task of combining multiple desirable traits into manageable units by using molecular markers to track each target gene or QTL independently. This allows breeders to work with specific trait combinations in a systematic manner, monitoring each marker's inheritance separately while working toward the integrated goal of developing varieties with multiple stacked traits, thereby reducing breeding process complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter of trait detection from phenotypic observation to genotypic analysis using molecular markers. This parameter change enables the simultaneous tracking of multiple traits at the DNA level, allowing breeders to monitor and combine several desirable traits in parallel during the breeding process, thereby improving ease of manufacture despite the complexity of combining multiple traits.

Inventive Principle:
Principle #35Parameter changes
