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 seed yield, disease resistance, and environmental adaptability, making it challenging to produce consistent and superior soybean varieties using conventional breeding methods.
Innovation Solution
The introduction of the soybean variety D5703684, which can be crossed with itself or other plants to produce hybrid seeds and plants exhibiting traits such as herbicide resistance, disease resistance, and improved nutritional quality, using methods like backcrossing and genetic transformation to introduce specific loci and enhance desirable characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used to combine desirable traits, then soybean varieties can be developed, but the process is time-consuming and unpredictable
Solution Approach 1:
The patent applies parameter changes by modifying the genetic composition of soybean plants through the introduction of specific genetic loci (such as herbicide resistance genes, disease resistance genes, and quality trait genes) into the breeding program. This allows breeders to directly alter genetic parameters rather than relying on traditional random recombination, thereby increasing predictability and potentially reducing the time required to develop varieties with desired traits.
2Reliability
If multiple desirable traits are combined in a single variety, then the overall value and superiority of the variety is improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct modules, each responsible for introducing specific types of traits (herbicide resistance, disease resistance, quality traits, yield traits). This modular approach allows breeders to systematically combine different trait packages without overwhelming complexity, as each module can be developed and evaluated independently before integration into the final variety.
Solution Approach 2:
The patent applies universality by developing a multi-functional breeding program that can simultaneously address multiple trait categories (herbicide resistance, disease resistance, nutritional quality, yield) within a single integrated framework. The breeding methodology is designed to be universally applicable across different soybean breeding objectives, reducing the need for separate breeding programs for different trait combinations.
3Measurement precision
If replicated evaluations are conducted to accurately assess genetic worth, then selection accuracy is improved, but the time and resources required increase
Solution Approach 1:
The patent applies preliminary action by implementing early-generation screening methods that provide preliminary assessments of genetic worth before committing to time-consuming replicated evaluations. By using molecular markers, preliminary phenotypic screens, or selective indexing in early generations, breeders can identify promising lines that warrant further replicated testing, thereby reducing the overall time and resource investment required for accurate genetic assessment.
