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 using conventional breeding methods.
Innovation Solution
The soybean variety D5896414 is developed through specific breeding methods, including crossing and selection techniques, which allows for the introduction of desirable traits such as herbicide resistance, disease resistance, and improved nutritional quality, and can be used in breeding programs to produce hybrid seeds and new varieties with predictable characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to combine desirable traits, then genetic diversity and adaptability are improved, but the breeding process becomes time-consuming and unpredictable
Solution Approach 1:
The patent replaces conventional mechanical breeding methods (manual crossing, selection, and evaluation) with molecular marker technology and DNA-level analysis. This substitution enables breeders to identify and select for multiple desirable traits simultaneously at the molecular level, dramatically reducing the time required while maintaining genetic diversity and adaptability.
Solution Approach 2:
The patent changes the parameter of trait evaluation from phenotypic observation (which is slow and environment-dependent) to genotypic analysis using molecular markers. This parameter change allows for rapid, accurate identification of plants with desired genetic characteristics, reducing breeding cycle time while preserving genetic diversity.
2Productivity
If multiple desirable traits are combined in a single variety, then overall value and productivity are improved, but the complexity of inheritance makes selection difficult
Solution Approach 1:
The patent replaces complex phenotypic evaluation and pedigree tracking with molecular marker-assisted selection. This substitution simplifies the management of multiple trait inheritance by providing direct molecular evidence of gene presence, eliminating the need to track complex inheritance patterns through multiple generations.
Solution Approach 2:
The patent introduces molecular markers as intermediaries between the desired traits and the selection process. These markers serve as reliable indicators that directly indicate the presence of target genes, simplifying the selection of plants with multiple desirable traits despite complex inheritance patterns.
3Measurement precision
If replicated evaluations are conducted to accurately estimate genetic worth, then selection accuracy is improved, but the time and resource requirements increase
Solution Approach 1:
The patent replaces time-consuming replicated field evaluations with molecular marker analysis. This substitution provides accurate estimation of genetic worth directly from DNA samples, eliminating the need for multiple seasons of replicated phenotypic evaluation while maintaining or improving accuracy.
Solution Approach 2:
The patent performs genotypic analysis early in the breeding process, before phenotypic expression occurs. This preliminary action allows breeders to identify plants with desired genetic characteristics at the seedling stage, eliminating the need for lengthy replicated evaluations across multiple growing seasons.
