Solution Overview

Problem

Current wheat breeding methods face challenges in combining desirable traits such as high seed yield, disease resistance, drought tolerance, and improved milling properties into a single variety, while maintaining uniformity and stability across generations.

Innovation Solution

The development of the wheat variety W090340G1, 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 multiple desirable traits are combined into a single wheat variety through breeding, then the variety shows improved seed yield, disease resistance, and agronomic characteristics, but maintaining uniformity and stability across generations becomes difficult

Engineering Contradiction:
Improvecombination of desirable traitsVSAvoiduniformity and stability across generations
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The breeding process is segmented into distinct stages: initial cross-breeding to combine traits, followed by separate selection phases for disease resistance, yield, and uniformity. This allows systematic management of multiple traits while maintaining stability in the final variety.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Once a stable variety with combined desirable traits is developed, it is replicated and propagated through controlled breeding to maintain uniformity across generations. The successful genetic combination is copied and preserved in subsequent generations.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If genetic modification and locus conversion techniques are used to introduce traits, then herbicide resistance, disease resistance, and nutritional quality are improved, but the complexity of the breeding process increases

Engineering Contradiction:
Improveherbicide resistance, disease resistance, nutritional qualityVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Locus conversion techniques serve as intermediaries to introduce desired traits (herbicide resistance, disease resistance) into the wheat variety. These conversion techniques act as mediators that facilitate trait introduction while providing a systematic approach to manage the breeding complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The breeding process utilizes parameter changes at the genetic level through locus conversion to introduce specific traits. By changing genetic parameters systematically, multiple resistance and quality traits are introduced while maintaining control over the breeding complexity.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If rigorous breeding and selection methods are applied to ensure homozygosity and phenotypic stability, then uniformity is improved, but the time and resources required for development increase

Engineering Contradiction:
Improvehomozygosity and phenotypic stabilityVSAvoidbreeding development time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

Preliminary selection and screening are performed during the breeding process to identify plants showing desired homozygosity and stability early in development. This preliminary action reduces the time required for subsequent generations to achieve uniformity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The breeding program incorporates feedback mechanisms where phenotypic performance and genetic uniformity are continuously monitored. This feedback allows adjustment of selection criteria and breeding strategies to achieve homozygosity and stability more efficiently, reducing overall development time.

Inventive Principle:
Principle #23Feedback
