Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of stable, high-yielding soybean varieties that are agronomically sound and possess desirable traits such as disease resistance, drought tolerance, and improved fatty acid profiles is a time-consuming process requiring precise planning and resource efficiency, with existing methods taking six to twelve years from cross to delivery.
Innovation Solution
The introduction of the novel soybean variety 5PLSL31, which combines desirable traits like resistance to diseases, insects, and tolerance to drought and heat, along with improved fatty acid profiles, through a combination of genetic manipulation and breeding techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop new soybean varieties, then desirable traits can be combined in a single variety, but the process takes six to twelve years from first cross to finished seed delivery
Solution Approach 1:
The patent applies preliminary action by pre-establishing a diverse panel of soybean lines with known trait profiles before the breeding process begins. This allows breeders to select parents with complementary traits more efficiently and plan crossing strategies in advance, reducing the overall development time while maintaining the ability to combine multiple desirable traits in the final variety.
2Reliability
If multiple desirable traits are combined in a single soybean variety, then agronomic soundness and yield stability are improved, but the breeding process becomes more complex and resource-intensive
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct stages: establishing a panel of lines with specific trait combinations, selecting parent pairs for crossing, evaluating F1 and F2 generations, and finally developing stable varieties. This segmented approach allows systematic management of complexity and efficient tracking of multiple traits through each breeding stage.
Solution Approach 2:
The patent applies universality by creating a reusable panel of soybean lines that can serve multiple breeding objectives. The same panel can be used to develop varieties with different trait combinations by selecting different parent pairs, making the breeding system multi-functional and reducing overall process complexity.
3Productivity
If precise planning and efficient resource use are implemented in variety development, then the breeding process can be optimized, but changes in direction must be minimized which limits flexibility
Solution Approach 1:
The patent applies feedback by implementing systematic evaluation and characterization of soybean lines at each breeding stage. Performance data on multiple traits are collected and analyzed, allowing breeders to make informed decisions about which parent pairs to cross and which lines to advance. This feedback mechanism enables efficient resource allocation while maintaining flexibility to adjust breeding directions based on observed performance.
