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 such as disease resistance, drought tolerance, and improved fatty acid profiles, while existing methods face challenges in efficiently combining these traits in a single variety.
Innovation Solution
The development of the soybean variety XB31AG13, 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 genetic marker-assisted breeding to introduce desired traits and loci.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine multiple desirable traits, then the variety achieves stability and uniformity, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by using genetic marker-assisted selection to identify and select plants with desired traits before completing the full breeding cycle. This allows breeders to make informed decisions early in the process, reducing the time required to develop stable varieties while maintaining reliability through systematic trait tracking.
Solution Approach 2:
The patent implements feedback mechanisms through molecular marker analysis that provides real-time information about trait inheritance and expression. This feedback allows breeders to adjust breeding strategies, select optimal parent plants, and predict offspring characteristics, thereby accelerating the breeding process while ensuring variety stability.
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the variety achieves superior agronomic characteristics, but the breeding program complexity increases
Solution Approach 1:
The patent applies segmentation by breaking down the complex breeding program into manageable components: identifying individual genetic markers for each desired trait, selecting parent plants based on specific marker profiles, and tracking trait inheritance separately for each marker. This modular approach reduces program complexity while enabling the combination of multiple traits.
Solution Approach 2:
The patent implements universality by developing a standardized genetic marker-assisted selection system that can be applied to select for multiple different traits simultaneously. The same methodological framework and molecular techniques are used regardless of which specific traits are being combined, reducing the complexity increment when adding new trait combinations.
3Productivity
If genetic marker-assisted breeding is used to introduce desired traits, then the breeding efficiency is improved, but the technical requirements and resources increase
Solution Approach 1:
The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based selection. Instead of visually assessing and testing plant traits in the field, breeders use DNA marker analysis to identify plants with desired genetic markers, dramatically improving breeding efficiency while the technical requirements become more specialized but manageable.
