Innovation Solution
The development of the soybean variety XB36AL13, which is the result of careful breeding and selection, combining traits like resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, through a process involving backcrossing and molecular marker-assisted breeding to introduce desired traits and loci.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine multiple desirable traits in a single soybean variety, then the variety achieves improved yield, disease resistance, and agronomic characteristics, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by using molecular marker technology to identify and select plants with desired traits at early breeding stages, rather than waiting for full trait expression. This allows breeders to make informed selection decisions before completing the full breeding cycle, significantly reducing the time required to develop new varieties while maintaining trait reliability.
Solution Approach 2:
The patent implements feedback mechanisms through molecular marker-assisted selection, where genetic information is continuously monitored and fed back into the breeding decision-making process. This enables real-time adjustment of breeding strategies to ensure desired traits are successfully combined, improving both efficiency and reliability of variety development.
2Adaptability or versatility
If multiple desirable traits are combined into a single soybean variety through comprehensive breeding programs, then the variety achieves superior agronomic performance, but the complexity of the breeding process increases
Solution Approach 1:
The patent applies segmentation by breaking down the complex breeding process into distinct, manageable stages: initial parental selection based on molecular markers, intermediate generation screening, and final variety development. This segmentation allows breeders to focus on specific traits at each stage, reducing overall program complexity while achieving multiple trait combinations in the final variety.
Solution Approach 2:
The patent uses molecular markers as intermediaries to facilitate the combination of multiple desirable traits. These markers serve as mediators that link parental traits to offspring selection, enabling breeders to track and combine multiple traits simultaneously without being overwhelmed by the complexity of direct phenotypic selection for all traits.
3Manufacturing precision
If extensive breeding and selection processes are undertaken to develop new soybean varieties, then desirable traits are achieved, but resources are consumed inefficiently
Solution Approach 1:
The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based genetic analysis. This substitution allows for more precise identification of plants with desired traits without requiring extensive growing and evaluation of multiple generations, thereby reducing resource consumption while maintaining or improving selection accuracy.
Solution Approach 2:
The patent changes the selection parameter from phenotypic observation to molecular genetic markers. This parameter change enables earlier and more accurate identification of plants with desired traits, reducing the need for prolonged breeding trials and associated resource consumption while improving the precision of trait selection.
