Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
