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 across generations.
Innovation Solution
The development of the wheat variety W060346O1, 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 patent applies preliminary action by pre-introducing multiple desirable traits through genetic modification before traditional breeding begins. Transgenic techniques are used to incorporate disease resistance, drought tolerance, and other desired traits into the wheat genome in advance, eliminating the need for lengthy traditional breeding cycles to accumulate these traits through multiple generations of selection and crossing.
2Adaptability or versatility
If multiple traits are combined through breeding, then the functionality of the wheat variety improves, but the uniformity and stability of the variety across generations may deteriorate
Solution Approach 1:
The patent merges transgenic technology with traditional breeding methods to achieve both high functionality and stability. Multiple desirable traits are introduced through genetic modification and then consolidated through systematic backcrossing and selection processes, ensuring that the combined traits are stably inherited across generations while maintaining variety uniformity.
Solution Approach 2:
The patent employs feedback mechanisms through rigorous selection and evaluation processes at each breeding stage. Phenotypic and genotypic monitoring ensures that desired traits are properly incorporated and stably inherited, allowing breeders to identify and eliminate off-type plants, thereby maintaining uniformity and stability across generations.
3Manufacturing precision
If genetic modification techniques are used to introduce specific traits, then the precision of trait introduction improves, but the complexity of the breeding process increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct phases: initial genetic modification to introduce specific traits, followed by systematic backcrossing to recover the recurrent parent genome, and final selection to fix desired traits. This segmented approach manages complexity by handling trait introduction and variety recovery as separate, manageable steps rather than simultaneous processes.
