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 in a single wheat variety, while maintaining uniformity and stability across generations.
Innovation Solution
The development of the wheat variety XW14B, which involves genetic modification and locus conversion through transgenic techniques, including CRISPR/Cas system, to introduce traits like herbicide resistance, disease resistance, and altered nutritional quality, along with traditional breeding methods like backcrossing and selection to ensure uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to combine multiple desirable traits, then the complexity of the breeding process increases, but the uniformity and stability of trait expression across generations deteriorates
Solution Approach 1:
The patent applies CRISPR/Cas9 genome editing technology to precisely modify specific genetic loci in wheat, enabling controlled introduction of desirable traits such as disease resistance and improved agronomic characteristics while maintaining genomic stability and uniformity across generations through targeted single-locus conversions rather than traditional multi-generational breeding
2Adaptability or versatility
If multiple traits are combined through conventional breeding, then the desired trait combination is achieved, but the breeding time and generational cycles increase
Solution Approach 1:
The patent performs preliminary genetic modification through CRISPR/Cas9 editing to directly introduce desirable traits into the wheat genome at specific loci, eliminating the need for multiple generations of conventional breeding and selection, thereby significantly reducing the time required to develop new wheat varieties with combined desirable traits
3Manufacturing precision
If transgenic techniques are used to introduce traits, then the precision of trait introduction improves, but the complexity of the genetic modification process increases
Solution Approach 1:
The patent utilizes CRISPR/Cas9 genome editing technology to precisely target and modify specific genetic loci in wheat, enabling accurate introduction of desirable traits such as disease resistance and improved agronomic characteristics while maintaining controlled complexity through standardized molecular biology protocols
