Solution Overview

Problem

Current soybean breeding methods face challenges in developing stable, high-yielding soybean varieties that combine desirable traits such as disease resistance, drought tolerance, and improved agronomic qualities, which are difficult to predict and require extensive research and resources.

Innovation Solution

The development of the soybean variety A1026437, which is suited for early group 5 growing regions, involves specific breeding techniques including backcrossing and genetic transformation to introduce desired traits like herbicide resistance, disease resistance, and improved nutritional quality, while maintaining the variety's elite genetic background.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional breeding methods are used to combine desirable traits, then genetic diversity is improved, but the process requires extensive research and resources with unpredictable outcomes

Engineering Contradiction:
Improvecombination of desirable traitsVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs marker-assisted selection using DNA markers to track and select for desirable traits during breeding. This feedback mechanism allows breeders to predictably combine traits by monitoring genetic markers associated with desired characteristics, reducing the unpredictability of traditional breeding while maintaining genetic diversity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional phenotypic selection with molecular marker-based genotypic selection. Instead of visually assessing and selecting plants based on physical traits, the invention uses DNA marker analysis to identify and select plants carrying desired genetic markers, thereby substituting mechanical/visual selection methods with molecular biology techniques to achieve more predictable trait combination.

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

2Stability of the object's composition

If extensive breeding research is conducted to develop stable varieties, then variety stability is improved, but development time and resource requirements increase

Engineering Contradiction:
Improvevariety stabilityVSAvoidbreeding development time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent performs preliminary genetic analysis using DNA markers during early breeding stages to identify plants carrying desired traits. By conducting marker-assisted selection in advance rather than waiting for phenotypic expression, the breeding process can identify and select promising genotypes earlier, reducing the overall time required to develop stable varieties while maintaining genetic stability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention substitutes traditional multi-year field testing and phenotypic evaluation with molecular marker analysis that can be performed more rapidly in laboratory settings. This replacement of field-based mechanical selection with molecular biology techniques accelerates the identification of stable genetic lines, reducing development time while ensuring variety stability through precise genetic tracking.

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

3Adaptability or versatility

If multiple traits are combined in a single variety, then agronomic quality is improved, but the breeding process becomes more complex and costly

Engineering Contradiction:
Improveagronomic qualityVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses DNA marker feedback to track multiple trait-associated markers simultaneously during the breeding process. By monitoring several genetic markers in parallel, breeders can select for multiple desirable traits (such as disease resistance, yield, and quality characteristics) in a coordinated manner, making the combination of multiple traits more manageable and less complex than traditional methods.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The invention employs a universal marker-assisted selection platform that can be applied to select for multiple different traits using the same molecular biology techniques. This multi-functional approach allows the breeding program to target various agronomic qualities (disease resistance, yield, nutritional content) through a single integrated methodology, reducing the need for separate breeding programs for each trait and thereby simplifying the overall process.

Inventive Principle:
Principle #6Universality (Multi-functionality)
