Innovation Solution

The development of the wheat variety W030065A1, which is the result of a breeding program that combines desirable traits such as high seed yield, disease resistance, drought tolerance, and improved grain quality through careful selection and cross-pollination techniques, including modified pedigree selection and molecular marker-assisted breeding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional breeding methods are used to develop wheat varieties, then genetic diversity and adaptability are improved, but breeding time and complexity increase significantly

Engineering Contradiction:
ImproveadaptabilityVSAvoidbreeding time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Molecular marker-assisted selection provides continuous feedback on the genetic composition of breeding lines, allowing breeders to track desired traits through generations and make informed selection decisions, thereby reducing breeding time while maintaining genetic diversity

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional phenotypic selection (mechanical/visual assessment) with molecular marker-based genotypic selection, enabling earlier and more accurate identification of desirable traits, thus accelerating the breeding process without sacrificing adaptability

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

2Stability of the object's composition

If multiple breeding generations are advanced to achieve stability, then variety uniformity and stability are improved, but development time and resource requirements increase

Engineering Contradiction:
Improvevariety stabilityVSAvoidresource requirements
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

Molecular markers replace traditional multi-generation phenotypic testing by directly detecting the presence of desired genetic alleles, achieving variety stability verification in fewer generations and reducing resource requirements for field trials and maintenance

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

Solution Approach 2:

The breeding program performs preliminary molecular marker screening at early generations to identify lines with desired genetic composition, allowing selective advancement of only promising lines and reducing overall resource requirements for stability verification

Inventive Principle:
Principle #10Preliminary action

3Reliability

If disease resistance traits are incorporated through breeding, then crop protection and yield stability are improved, but breeding complexity and selection difficulty increase

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Molecular markers substitute for complex phenotypic disease resistance testing by directly detecting resistance-associated genetic markers, simplifying the selection process and reducing breeding program complexity while maintaining reliable disease resistance

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

Solution Approach 2:

Molecular markers serve as intermediaries between disease resistance genes and phenotypic expression, allowing indirect selection of resistant lines through marker detection rather than direct disease challenge testing, thereby reducing breeding complexity

Inventive Principle:
Principle #24Intermediary (Mediator)
