Soybean Cultivar S170068 Breeding Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is a time-consuming process that requires precise planning and resource management, aiming to combine desirable traits such as high seed yield, disease resistance, drought tolerance, and improved fatty acid profiles, while existing methods are inefficient in achieving these goals within a reasonable timeframe.
Innovation Solution
The introduction of soybean cultivar S170068, which is developed through a process involving crossing, mutagenesis, and transformation to incorporate traits like herbicide resistance, disease resistance, and improved agronomic qualities, along with the use of regenerable cells in tissue culture for consistent production of plants with specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to develop new cultivars with multiple desirable traits, then the cultivars achieve improved yield, disease resistance, and agronomic quality, 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 germplasm with specific desirable traits (high yield, disease resistance, drought tolerance, improved fatty acid profiles) before crossing. This preliminary characterization and selection of parents with known trait profiles accelerates the breeding process by 6-12 years through systematic forward planning and efficient resource allocation from the outset
2Productivity
If multiple crossing and selection cycles are performed to combine desirable traits, then the resulting cultivar achieves superior agronomic performance, but the process requires precise forward planning and efficient resource management with minimum changes in direction
Solution Approach 1:
The patent segments the breeding process into distinct phases: parental selection, crossing, progeny evaluation, and cultivar development. Each phase has specific objectives and criteria, allowing systematic progression while maintaining precise forward planning. The segmentation enables efficient resource management by focusing efforts on specific traits at each stage rather than attempting to optimize all traits simultaneously
Solution Approach 2:
The patent utilizes parameter changes by evaluating progeny for specific quantitative traits (yield components, disease resistance levels, fatty acid composition) and selecting individuals that meet predetermined thresholds. This systematic parameter-based selection reduces breeding complexity by providing clear decision criteria at each generation, minimizing unnecessary changes in direction
