Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean cultivars face challenges in combining desirable traits such as higher seed yield, disease resistance, herbicide tolerance, and improved fatty acid profiles, which are time-consuming to develop and require precise planning and resource efficiency.
Innovation Solution
Development of a new soybean cultivar (94402428) with integrated traits like herbicide resistance, disease tolerance, and altered fatty acid composition, achieved through genetic modification and traditional breeding methods, including introgression of transgenic and mutant traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine desirable traits (higher seed yield, disease resistance, herbicide tolerance, improved fatty acid profiles), then the cultivar can achieve stable and high yielding performance, but the development process is time-consuming (6-12 years) and requires precise forward planning and efficient resource use
Solution Approach 1:
The patent combines traditional breeding methods with genetic modification techniques to integrate multiple desirable traits (seed yield, disease resistance, herbicide tolerance, fatty acid profiles) into a single cultivar. This merging of approaches allows for accelerated development while maintaining the stability and reliability achieved through conventional breeding, thereby reducing the 6-12 year development timeline without sacrificing performance consistency
Solution Approach 2:
The patent employs preliminary action by using genetic modification to introduce and establish desirable traits in early generations, before completing the full traditional breeding cycle. This allows the cultivar to inherit beneficial traits (disease resistance, herbicide tolerance, improved fatty acid profiles) from transformed parent lines, significantly reducing the time required to develop stable high-yielding varieties while maintaining agricultural soundness
2Adaptability or versatility
If multiple desirable traits are combined in a single cultivar through breeding, then agronomic quality and yield are improved, but the complexity of the breeding program and resource requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: (1) genetic modification of parent lines to introduce specific traits (disease resistance, herbicide tolerance, fatty acid profiles), (2) controlled crossing and backcrossing to transfer traits to the target cultivar, and (3) evaluation and selection. This segmentation allows for systematic integration of multiple traits while managing program complexity through structured implementation
Solution Approach 2:
The patent uses intermediary techniques including backcrossing to recurrent parents and controlled hybridization to facilitate the transfer of multiple traits from genetically modified lines to the target cultivar. These intermediary methods simplify the overall breeding program by providing controlled pathways for trait integration, reducing the complexity of directly combining multiple traits in a single complex breeding scheme
