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 6PDLD01B, which involves genetic modification and locus conversion through transgenic techniques, allowing for the introduction of traits like herbicide resistance, disease resistance, and altered nutritional content, along with traditional breeding methods to create stable and uniform wheat plants.
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 significantly, but the uniformity and stability of the final variety may be compromised
Solution Approach 1:
The patent segments the complex breeding process by using molecular markers to identify and track specific trait loci independently. This allows breeders to select for multiple traits separately through marker-assisted selection, then combine them systematically, reducing the overall complexity of managing multiple traits simultaneously in traditional breeding.
Solution Approach 2:
Molecular markers serve as intermediaries between the desired traits and the selection process. Instead of directly selecting for complex phenotypic traits, breeders use molecular markers as proxies to identify and select for specific genetic loci, simplifying the selection process and improving accuracy in combining multiple traits.
2Stability of the object's composition
If multiple generations of breeding are performed to stabilize traits, then the time required increases, but maintaining uniformity across generations becomes more challenging
Solution Approach 1:
The patent applies preliminary action by using molecular markers to identify and select for desired trait loci early in the breeding process, before phenotypic expression is fully observable. This allows breeders to make informed selection decisions earlier, reducing the number of generations needed to stabilize traits and achieve uniformity across generations.
Solution Approach 2:
Molecular marker analysis provides continuous feedback on the genetic composition of breeding lines throughout the breeding process. This feedback mechanism allows breeders to monitor the presence and stability of desired trait loci across generations, enabling及时调整 of selection strategies to maintain uniformity and reduce breeding cycle time.
3Manufacturing precision
If genetic modification techniques are used to introduce specific traits, then the precision of trait introduction improves, but the complexity of the genetic structure increases
Solution Approach 1:
The patent extracts and isolates specific trait loci using molecular markers, allowing breeders to identify and work with individual genetic elements independently. This extraction approach enables precise introduction of specific traits through targeted selection or modification, while keeping the overall genetic structure manageable by focusing on specific loci rather than the entire genome.
