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 a novel soybean variety, XB005G14, 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 comprehensive breeding program that includes backcrossing and genetic marker-assisted breeding to introduce desired traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop soybean varieties with multiple desirable traits, then trait combination is achieved, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent employs molecular markers as intermediary tools to identify and select plants carrying desired traits. These markers serve as proxies for complex trait combinations, allowing breeders to screen for multiple traits simultaneously through DNA analysis rather than traditional phenotypic observation, significantly accelerating the breeding process while maintaining trait combination accuracy
2Reliability
If extensive breeding programs are implemented to combine multiple traits, then variety improvement is achieved, but resource consumption increases
Solution Approach 1:
The patent replaces traditional mechanical and manual breeding methods with molecular marker-assisted selection. Instead of relying on labor-intensive field trials, phenotypic scoring, and manual cross-breeding operations, the system uses DNA-based molecular markers to identify and select plants with desired traits, dramatically reducing resource consumption while improving variety stability through precise genetic selection
3Stability of the object's composition
If multiple generations of breeding are conducted to achieve trait stability, then variety uniformity is improved, but the development timeline extends
Solution Approach 1:
The patent performs preliminary genetic analysis using molecular markers at early breeding stages to identify plants carrying desired traits before advancing to subsequent generations. This preliminary identification allows breeders to make informed selection decisions early in the process, reducing the number of generations needed to achieve trait stability and uniformity while maintaining high breeding efficiency
