Soybean D4012368 Breeding via Molecular Markers
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, with conventional breeding methods lacking control over genetic combinations and requiring extensive resources.
Innovation Solution
The soybean variety D4012368 is developed through specific breeding methods, including crossing and selection techniques, which introduce desirable traits such as herbicide resistance, disease resistance, and improved nutritional quality, and can be used in breeding programs to produce hybrid seeds and plants with consistent performance across different environments.
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 applies parameter changes by utilizing molecular markers to track and select specific genetic parameters during breeding. Instead of relying on traditional phenotypic selection that requires multiple years of field testing, the invention uses DNA-based markers to directly identify and select plants with desired genetic combinations, dramatically accelerating the breeding process while maintaining genetic diversity and adaptability
2Adaptability or versatility
If conventional breeding methods are used to combine desirable traits, then trait combination flexibility is improved, but resource intensity increases
Solution Approach 1:
The patent replaces the mechanical and resource-intensive process of traditional breeding (manual crossing, extensive field planting, phenotypic evaluation) with a molecular biology-based system. Molecular markers allow breeders to identify and select desired trait combinations at the DNA level, reducing the need for large-scale field trials and manual labor while maintaining flexibility in combining traits
3Measurement precision
If molecular markers are used for trait identification, then selection precision is improved, but detection complexity increases
Solution Approach 1:
The patent uses molecular markers as intermediary tools that bridge the gap between complex genetic information and practical breeding decisions. These markers serve as visible, detectable indicators that correlate with desired traits, allowing breeders to indirectly select for complex genetic characteristics through simpler, more precise molecular assays rather than attempting to directly measure or evaluate the complex traits themselves
