Innovation Solution

The development of the wheat variety W060401B1, which involves genetic modification and locus conversion techniques, including transgenic approaches and backcrossing, to introduce traits like herbicide resistance, disease resistance, and improved nutritional quality, while ensuring homozygosity and phenotypic stability through rigorous breeding and selection methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional wheat breeding methods are used to combine multiple desirable traits, then the complexity of the breeding process increases significantly, but the uniformity and stability of the resulting variety may be compromised

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

Solution Approach 1:

The breeding process is segmented into distinct phases: initial crossing to combine traits, followed by separate backcrossing generations (BC1, BC2, BC3) to recover the recurrent parent genome, and final selection. This segmentation allows systematic integration of multiple traits while maintaining process control and reducing overall complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Molecular markers are used for preliminary identification and tracking of desirable traits during the breeding process. This preliminary action allows early selection of plants carrying target traits, reducing the need for extensive phenotypic screening in later generations and simplifying the overall breeding workflow.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If extensive backcrossing is performed to achieve homozygosity and phenotypic stability, then the time required for variety development increases, but the uniformity of the final variety is improved

Engineering Contradiction:
Improvephenotypic stabilityVSAvoidbreeding cycle duration
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

Molecular marker analysis provides continuous feedback on the genetic composition of breeding lines throughout the backcrossing process. This feedback mechanism allows real-time monitoring of genome recovery and trait retention, enabling informed decisions about when to proceed to the next generation or select specific plants for advancement, thereby optimizing the breeding timeline.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Traditional phenotypic selection methods are replaced or supplemented with molecular marker-based selection. This substitution accelerates the identification of homozygous lines and desired trait combinations, reducing the time required for multiple generations of backcrossing and selection while maintaining genetic stability.

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

3Manufacturing precision

If multiple traits are introduced through genetic modification and backcrossing, then the manufacturing precision of the breeding process must be high, but the ease of manufacture decreases

Engineering Contradiction:
Improvetrait integration precisionVSAvoidbreeding operation ease
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

Molecular markers serve as intermediaries between the visible phenotypic traits and the underlying genetic composition. These markers facilitate precise tracking and selection of multiple traits simultaneously during backcrossing, achieving high manufacturing precision without requiring complex manual tracking and selection procedures, thus maintaining ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)
