Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean varieties is a time-consuming and unpredictable process due to the complexity of combining desirable traits like disease resistance, yield, and environmental adaptability, making it challenging for breeders to consistently produce superior varieties.
Innovation Solution
The soybean variety 0385457 is developed through specific breeding methods, including crossing and selection techniques, which allows for the introduction of traits such as herbicide resistance, disease resistance, and improved nutritional quality, and can be used in various breeding protocols to produce hybrid seeds and plants with desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop new soybean varieties, then genetic diversity and adaptability are improved, but the breeding process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by pre-screening parental lines for desirable traits (herbicide resistance, disease resistance, nutritional quality) before crossing. This advance preparation of parental germplasm with known superior characteristics reduces the time needed for later selection and evaluation, while maintaining genetic diversity through careful selection of parents from different genetic backgrounds
2Productivity
If multiple traits are combined in a single variety to improve overall performance, then agronomic quality is enhanced, but the complexity of inheritance makes selection difficult
Solution Approach 1:
The patent applies segmentation by developing parental lines that each excel in specific traits (one parent for herbicide resistance, another for disease resistance, another for nutritional quality). This divides the complex multi-trait breeding problem into manageable segments, allowing breeders to combine proven single-trait performers rather than attempting to select all traits simultaneously in a single population
Solution Approach 2:
The patent changes the approach from selecting multiple traits in one population to evaluating and combining lines based on specific parameter excellence. Each parental line is optimized for particular parameters (herbicide resistance, disease resistance, protein content, oil content), and these parameter-optimized lines are then crossed to produce offspring with combined superior parameters
3Productivity
If superior individual plants are selected based on single observations, then selection efficiency is improved, but the true genotypic value remains masked by environmental factors
Solution Approach 1:
The patent applies preliminary action by conducting multi-environment testing of parental lines before using them in crossing programs. This preliminary evaluation across multiple locations and years provides a more accurate assessment of true genotypic value, reducing the impact of environmental masking and improving the reliability of subsequent selection decisions
Solution Approach 2:
The patent incorporates feedback mechanisms by systematically evaluating breeding lines across multiple environments and using this information to guide subsequent selection and crossing decisions. Performance data from previous generations and test locations feed into the selection process, allowing breeders to identify lines with consistent superior performance rather than those that merely performed well in a single observation
