Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is a time-consuming and unpredictable process due to the complexity of identifying genetically superior plants, with conventional breeding methods lacking control at the DNA level, leading to high research costs and variability in resulting cultivars.
Innovation Solution
The introduction of soybean cultivar S070149, which offers resistance to glyphosate herbicides and excellent agronomic characteristics, along with methods for producing hybrid seeds and plants through selfing, backcrosses, and genetic transformation, allowing for the introduction of desirable traits such as herbicide resistance and improved yield potential.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop new soybean cultivars, then genetic diversity and trait combination are improved, but the process becomes time-consuming and unpredictable
Solution Approach 1:
The patent replaces conventional mechanical breeding methods (manual crossing, selection, and evaluation) with molecular marker-assisted selection. DNA markers are used to directly identify and select plants with desired genetic traits, eliminating the need for time-consuming phenotypic evaluation and multiple generations of breeding. This substitution of molecular biology techniques for traditional breeding mechanics resolves the contradiction by maintaining genetic diversity while dramatically reducing the time required.
2Adaptability or versatility
If conventional breeding methods are used, then new genetic combinations are generated, but control at the DNA level is lacking leading to high research costs
Solution Approach 1:
The patent replaces complex, uncontrolled conventional breeding procedures with a systematic molecular marker-assisted approach. DNA markers provide direct visualization and selection of specific genetic combinations, replacing the need for complex pedigree tracking and phenotypic selection across multiple generations. This reduces breeding program complexity while maintaining the ability to generate diverse genetic combinations.
Solution Approach 2:
The patent introduces molecular markers as intermediaries between the breeder and the genetic traits. These markers serve as detectable signals that indicate the presence of desired genes, allowing breeders to select plants with specific genetic combinations without needing to track complex breeding histories or wait for phenotypic expression. This intermediary system simplifies the breeding process while maintaining genetic diversity.
3Measurement precision
If replicated observations are used to estimate genetic worth, then measurement accuracy is improved, but the time and resources required increase
Solution Approach 1:
The patent replaces repeated phenotypic observations with a single DNA-based genetic evaluation. Molecular markers directly detect the presence of desired genetic traits at the DNA level, providing accurate measurement of genetic worth without requiring multiple generations of replicated field trials. This substitution maintains measurement precision while eliminating the time-consuming nature of replicated phenotypic evaluation.
