Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as higher seed yield, disease resistance, drought tolerance, and improved fatty acid profile, while existing methods struggle to efficiently introduce and stabilize these traits in a single cultivar.
Innovation Solution
The introduction of soybean cultivar S170117, which includes methods for crossing, mutagenesis, and transformation to introduce transgenic or mutant traits, such as herbicide resistance and disease resistance, and the use of regenerable cells in tissue culture to produce plants with consistent morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine desirable traits, then the cultivar achieves stable inheritance of traits, but the development process takes 6-12 years and requires multiple generations of crossing and selection
Solution Approach 1:
The patent applies preliminary action by first identifying and selecting parental lines with specific desirable traits (such as disease resistance, yield potential, and fatty acid profile) before initiating the crossing program. This advance planning and preparation of parental germplasm allows the breeding process to proceed more efficiently through predefined selection criteria, reducing the overall time required while maintaining trait stability.
2Adaptability or versatility
If multiple crossing and selection steps are performed to combine desirable traits, then the cultivar achieves superior trait combination, but the process requires precise forward planning and efficient resource use with minimum changes in direction
Solution Approach 1:
The patent segments the breeding program into distinct phases: parental selection, initial crossing, F1 evaluation, backcrossing if needed, and final selection. Each phase has specific objectives and selection criteria. This segmentation allows the complex task of combining multiple traits to be managed through a series of simpler, more controllable steps, reducing program complexity while achieving superior trait combinations.
Solution Approach 2:
The patent employs universal selection criteria that can be applied across different trait combinations and parental lines. The same evaluation framework is used whether selecting for disease resistance, yield, or fatty acid profile, making the breeding program more efficient and less complex. This multi-functional approach allows the same procedural framework to handle various breeding objectives.
3Stability of the object's composition
If conventional breeding methods are used to introduce new traits, then the cultivar maintains genetic stability, but the process is time-consuming and requires six to twelve years from first cross to marketing
Solution Approach 1:
The patent implements feedback mechanisms at each breeding stage where selected plants are evaluated against predefined criteria for trait expression and genetic stability. This feedback allows for immediate selection of plants that maintain genetic stability while expressing desired traits, enabling faster progression through breeding generations. The feedback loop ensures that only genetically stable plants advance, accelerating the development rate without sacrificing stability.
