Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with improved traits such as disease resistance, drought tolerance, and herbicide resistance, which are difficult to predict and require extensive research efforts due to the complexity of genetic combinations and environmental factors.
Innovation Solution
The development of the soybean variety 01072864, which incorporates specific genetic modifications and locus conversions, including transgenic genes for herbicide resistance and disease resistance, achieved through genetic transformation and backcrossing techniques, allowing for the introduction of desired traits while maintaining the original variety's morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity and trait combination are achieved, but the process requires extensive research efforts and time due to the complexity of genetic combinations and environmental factors
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits (herbicide resistance, disease resistance, yield characteristics) before crossing. The parental germplasm is carefully chosen and pre-evaluated to ensure they possess the target traits, which accelerates the breeding process by avoiding the need to screen through numerous random crosses and environmental variations.
Solution Approach 2:
The patent employs feedback mechanisms through systematic evaluation and selection of progeny at multiple generations (F2, F3, F4, etc.). Performance data on herbicide resistance, disease resistance, and yield are collected and used to guide subsequent selection decisions, allowing breeders to iteratively improve varieties while tracking progress toward specific breeding objectives.
2Reliability
If multiple traits are combined in a single soybean variety, then agronomic performance and resistance are improved, but the genetic complexity and difficulty of stable inheritance increase
Solution Approach 1:
The patent applies segmentation by developing parental lines that each carry specific, well-defined traits (e.g., one parent with herbicide resistance, another with disease resistance). This modular approach allows individual traits to be independently validated and then combined through controlled crosses, making the complex multi-trait variety development more manageable and predictable.
Solution Approach 2:
The patent utilizes parameter changes by evaluating progeny across multiple generations for specific quantitative and qualitative parameters (herbicide resistance levels, disease resistance scores, yield metrics). Statistical analysis and selection thresholds are applied to these parameters to ensure stable inheritance of desired traits while filtering out unwanted genetic variations.
3Measurement precision
If extensive screening and evaluation are performed to ensure variety stability, then trait reliability is improved, but productivity and breeding speed are reduced
Solution Approach 1:
The patent applies partial action by implementing a tiered evaluation system where not all progeny are screened with the same intensity. Initial screening uses rapid, less resource-intensive methods to identify promising candidates, followed by more rigorous evaluation only for selected individuals. This approach maintains measurement precision for key traits while reducing overall time and resource requirements.
Solution Approach 2:
The patent uses preliminary action by conducting preliminary evaluations of parental lines and early-generation progeny using rapid assessment methods. This allows breeders to identify and eliminate non-promising lines early in the breeding process, concentrating resources on the most promising candidates and thereby increasing overall breeding productivity without sacrificing the accuracy of final variety selection.
