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
Development of the soybean variety XBP10002, which is the result of careful breeding and selection, combining traits such as resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, through a comprehensive breeding program involving cross-pollination and genetic marker-assisted selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional soybean breeding methods are used to develop new varieties with multiple desirable traits, then the variety can achieve comprehensive trait improvement, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-establishing a comprehensive set of desirable traits in the parental germplasm before the actual breeding process. The parental lines are selected and prepared in advance to carry multiple target traits (disease resistance, drought tolerance, improved fatty acid profiles, etc.), which then can be efficiently combined in the offspring through controlled crossing, significantly reducing the overall breeding time required.
Solution Approach 2:
The patent merges multiple desirable traits into a single breeding program by combining several breeding objectives simultaneously. Instead of breeding for one trait at a time over multiple generations, the method integrates multiple traits (yield, disease resistance, stress tolerance, compositional traits) into a unified breeding strategy, achieving comprehensive improvement in a condensed timeframe.
2Adaptability or versatility
If multiple desirable traits are combined in a single soybean variety, then the variety achieves superior performance, but the complexity of the breeding program increases
Solution Approach 1:
The patent segments the complex breeding program into distinct, manageable phases and components. Each desirable trait is assigned to specific parental lines or breeding objectives, allowing the program to be organized into modular sections (e.g., disease resistance component, stress tolerance component, compositional trait component). This segmentation reduces overall program complexity by making each component independently manageable and selectable.
Solution Approach 2:
The patent employs universal parental germplasm lines that serve multiple functions simultaneously. Certain parental lines are selected that carry multiple desirable traits across different categories (yield, disease resistance, stress tolerance), allowing a single parental line to contribute to multiple breeding objectives at once, thereby reducing the total number of separate breeding operations needed.
3Productivity
If conventional breeding methods are used without genetic marker assistance, then the breeding process remains simpler, but the efficiency of combining desirable traits is reduced
Solution Approach 1:
The patent replaces conventional mechanical breeding methods (relying solely on phenotypic selection and manual crossing) with genetic marker-assisted selection. Molecular markers are used to identify and select for desirable traits at the genetic level, substituting the labor-intensive phenotypic evaluation process with faster, more accurate molecular detection. This substitution dramatically increases trait combination efficiency while adding controlled complexity through the integration of molecular biology tools.
