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 are limited in achieving these goals efficiently.
Innovation Solution
The introduction of soybean cultivar S170157, which is developed through crossing and mutagenesis, incorporating traits like glyphosate herbicide tolerance and disease resistance, and can be used in various breeding methods including selfing, backcrosses, and transformation to produce superior hybrid seeds and plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the cultivar achieves improved seed yield and disease resistance, but the development process takes 6-12 years and requires extensive resources
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits (disease resistance, yield potential, fatty acid profile) before crossing. The parental germplasm is evaluated and prepared in advance with known characteristics, allowing the breeding program to start from a optimized foundation rather than discovering traits during the breeding process, thus reducing the overall development time while maintaining reliability of desired traits
2Productivity
If multiple desirable traits are combined in a single cultivar, then the agronomic quality and seed yield improve, but the breeding program complexity and resource requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: parental line selection and characterization, controlled crossing, progeny evaluation, and cultivar development. Each phase focuses on specific traits (e.g., disease resistance in parental selection, yield in progeny evaluation), allowing complex multi-trait combination to be managed through systematic, modular steps rather than attempting to address all traits simultaneously, thus reducing program complexity while maintaining high productivity
3Loss of time
If the breeding program maintains precise forward planning and efficient resource use, then the development time is reduced, but the ability to adapt to new goals or discoveries is limited
Solution Approach 1:
The patent applies dynamics by designing a flexible breeding program where evaluation criteria and selection priorities can be adjusted based on emerging data and changing program goals. The systematic evaluation framework allows re Prioritization of traits (e.g., shifting focus from yield to disease resistance if new threats emerge) without requiring complete program redesign, thus maintaining efficient timeline while enabling adaptation to new objectives or discoveries during the 6-12 year development period
