Solution Overview

Problem

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

Innovation Solution

The development of the wheat variety W060347A1, which involves genetic modification and locus conversion through transgenic techniques, including the introduction of specific genes for traits like herbicide resistance, disease resistance, and abiotic stress tolerance, along with traditional breeding methods like backcrossing and selection, to create a stable and uniform germplasm.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional breeding methods are used to combine multiple desirable traits, then the number of traits combined increases, but the time required for breeding and the complexity of the breeding program increase significantly

Engineering Contradiction:
Improvenumber of traits combinedVSAvoidbreeding time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The breeding program is segmented into distinct phases: initial cross-breeding to combine traits, followed by systematic backcrossing with the original variety to stabilize the genome while retaining desired traits. This segmentation allows efficient progression from trait combination to variety stabilization without excessive time loss

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary backcrossing operations early in the breeding process to gradually replace the donor parent's genome with the recurrent parent's genome while retaining the desired trait. This preliminary action accelerates the overall breeding timeline by preparing the genetic background in advance rather than waiting for natural segregation

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If multiple generations of backcrossing are performed to maintain variety stability, then genetic uniformity is improved, but the number of breeding steps and program complexity increase

Engineering Contradiction:
Improvegenetic uniformityVSAvoidbreeding program complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The breeding program incorporates feedback mechanisms through systematic selection and evaluation at each backcrossing generation. Plants are screened for both the desired introduced trait and fidelity to the original variety's characteristics, allowing real-time adjustment and ensuring genetic uniformity without requiring excessive breeding steps

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent changes key parameters during the breeding process, including the number of backcrossing generations performed and the selection criteria applied at each stage. By optimizing these parameters, the program achieves genetic uniformity with fewer steps than traditional approaches, reducing overall complexity while maintaining stability

Inventive Principle:
Principle #35Parameter changes
