Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with improved traits such as disease resistance, herbicide tolerance, and nutritional quality, 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 01067788, which incorporates specific genetic modifications through transgenic gene introduction and genome editing techniques, such as Cas endonucleases, to confer traits like herbicide resistance, disease resistance, and improved nutritional quality, along with a breeding program that includes methods like backcrossing and marker-assisted selection to stabilize these traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity can be maintained, but the breeding process becomes time-consuming and unpredictable due to complex genetic combinations and environmental factors
Solution Approach 1:
The patent replaces conventional mechanical breeding methods (crossing, selection, and environmental testing) with genetic engineering techniques. Specific gene sequences are directly introduced or modified to confer desired traits such as herbicide tolerance and disease resistance, eliminating the need for extensive multi-generational breeding and field testing while achieving predictable trait expression.
2Adaptability or versatility
If multiple traits are combined in a single soybean variety through conventional breeding, then genetic diversity is maintained, but the complexity of genetic combinations makes trait prediction and selection extremely difficult
Solution Approach 1:
The patent segments the complex trait improvement process into individual gene targeting steps. Each desired trait (herbicide tolerance, disease resistance, nutritional quality) is addressed by introducing or modifying specific gene sequences independently, rather than attempting to combine multiple traits through complex multi-generational crosses and selection processes.
Solution Approach 2:
The patent uses molecular markers and specific gene sequences as intermediaries to achieve trait combination. These genetic markers serve as reliable indicators that allow breeders to select for multiple traits simultaneously through marker-assisted selection, simplifying the complexity of combining multiple improved traits in a single variety.
3Reliability
If extensive field testing and environmental evaluation are conducted to ensure variety stability, then variety reliability is improved, but the research effort and resources required increase significantly
Solution Approach 1:
The patent incorporates molecular marker feedback systems that provide direct genetic information about trait presence and stability. This feedback mechanism allows for early identification of varieties with desired traits and stable inheritance patterns, reducing the need for extensive multi-location and multi-year field testing while ensuring variety reliability.
