Solution Overview

Problem

The development of new soybean varieties is a time-consuming and unpredictable process due to the complexity of combining desirable traits such as higher seed yield, disease resistance, and environmental adaptability, with conventional breeding methods lacking control over genetic combinations and requiring extensive resources.

Innovation Solution

The soybean variety D4253681 is developed through specific breeding methods, including crossing and selection techniques, which introduce desirable traits like herbicide resistance, disease resistance, and improved nutritional quality, and can be used in various breeding protocols to produce hybrid seeds and plants with consistent performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional breeding methods are used to combine desirable traits, then genetic diversity and adaptability are improved, but the breeding process becomes time-consuming and unpredictable

Engineering Contradiction:
Improvegenetic diversityVSAvoidbreeding process duration
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-screening parental lines for specific desirable traits (herbicide resistance, disease resistance, nutritional quality) before crossing. This advance preparation of parental germplasm with known characteristics reduces the time needed for subsequent selection and evaluation in the breeding process.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If extensive parental combinations are tested to achieve desirable traits, then trait combination quality is improved, but resource consumption increases

Engineering Contradiction:
Improvetrait combination qualityVSAvoidresource consumption
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent applies local quality by focusing breeding efforts on specific key traits rather than evaluating all possible characteristics. Parental lines are selected based on predetermined criteria for herbicide resistance, disease resistance, and nutritional quality, allowing concentrated resource allocation to achieve precise trait combinations without exhaustive testing of all parental combinations.

Inventive Principle:
Principle #3Local quality

3Reliability

If multiple generations of selection are performed to improve yield and quality, then variety superiority is improved, but the breeding program complexity increases

Engineering Contradiction:
Improvevariety superiorityVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies mechanics substitution by replacing complex multi-generational field selection processes with molecular marker-assisted selection. DNA markers are used to directly identify and track inheritance of desirable traits through generations, substituting the mechanical/physical process of phenotypic evaluation with a molecular-based system that reduces program complexity while maintaining variety superiority.

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