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 improved traits such as disease resistance, drought tolerance, and altered fatty acid profiles, but face challenges in efficiently combining these desirable characteristics.
Innovation Solution
The development of the soybean variety XBP48006, which is the result of careful breeding and selection, combining traits like resistance to aerial blight, brown stem rot, and improved fatty acid composition, along with molecular marker profiles for identification and introgression of new traits, facilitating efficient breeding and trait introduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding processes are used to combine multiple desirable traits, then disease resistance and yield improvement are achieved, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent employs molecular marker technology to provide feedback on the genetic composition of breeding plants. By using DNA markers linked to desirable traits (such as disease resistance genes Rps1c, Rps1k, Rps6), breeders can selectively identify and propagate plants carrying these traits without waiting for phenotypic expression, thereby accelerating the breeding process while maintaining reliable disease resistance
Solution Approach 2:
The patent replaces traditional mechanical/phenotypic selection methods with molecular-level detection. Instead of visually assessing disease resistance or conducting field trials to evaluate trait inheritance, the invention uses DNA-based molecular markers to detect and select for desirable traits at the genetic level, significantly reducing the time and resources required for breeding while improving reliability
2Adaptability or versatility
If multiple desirable traits are combined in a single soybean variety, then agronomic performance and nutritional value are improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent segments the breeding process into distinct genetic components that can be independently tracked and combined. By using specific molecular markers for different traits (e.g., separate markers for Rps1c, Rps1k, Rps6 resistance genes, and markers for fatty acid composition), the breeding program can systematically assemble multiple desirable traits in a modular fashion, reducing overall program complexity while achieving superior agronomic performance
3Productivity
If molecular marker profiles are used for trait identification and introgression, then breeding efficiency is improved, but the need for sophisticated detection methods increases
Solution Approach 1:
The patent uses molecular markers as intermediary indicators that indirectly reveal the presence of desirable traits. Instead of directly detecting complex traits like disease resistance or fatty acid composition, the invention employs simpler-to-detect DNA markers that are genetically linked to these traits, thereby improving breeding efficiency while managing detection complexity through the use of these intermediary molecular signals
