Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits like disease resistance, drought tolerance, and improved fatty acid profiles, but face challenges in efficiently combining these traits in a single variety.
Innovation Solution
The development of the soybean variety XB26W12, which is the result of careful breeding and selection, combining traits such as resistance to aerial web blight, aphid antibiosis, and improved agronomic characteristics, through a process involving backcrossing and genetic marker-assisted breeding to introduce desired traits and loci.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional soybean breeding processes are used to develop new varieties with multiple desirable traits, then the variety can achieve comprehensive trait improvement, but the development process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-establishing a set of desirable traits and their corresponding genetic markers before the breeding process begins. The breeding program is designed with predetermined goals for yield, disease resistance, and fatty acid profiles, allowing for targeted selection and reducing the overall breeding cycle time while maintaining comprehensive trait improvement.
Solution Approach 2:
The patent implements feedback mechanisms through the use of genetic markers that provide real-time information about trait inheritance. This allows breeders to monitor and select for desired traits more efficiently, adjusting the breeding strategy based on observed results and marker data, thereby reducing the time required to develop varieties with multiple desirable traits.
2Adaptability or versatility
If multiple desirable traits are combined in a single soybean variety, then the variety achieves superior performance, but the breeding complexity and resource requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into manageable modules, each focused on specific traits such as yield, disease resistance, and fatty acid profiles. Genetic markers are used to segment the selection process, allowing breeders to work on individual traits separately and then integrate them, reducing the overall complexity of the breeding program.
Solution Approach 2:
The patent uses genetic markers as intermediaries between the desired traits and the breeding process. These markers serve as mediators that simplify the selection and combination of multiple traits by providing objective, measurable indicators of trait presence and inheritance, thereby reducing the complexity of managing and integrating multiple desirable characteristics.
3Reliability
If extensive breeding and selection steps are performed to achieve stable, high-yielding varieties, then the variety achieves superior agronomic characteristics, but the development process becomes more resource-intensive
Solution Approach 1:
The patent replaces traditional mechanical and manual breeding methods with marker-assisted selection and molecular tools. This substitution reduces the number of physical crossing and selection steps required, thereby reducing the resources needed while maintaining or improving variety stability and agronomic characteristics through more precise genetic control.
