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 inheritance and the lack of control over genetic traits, requiring extensive research and resources to achieve desirable traits such as higher seed yield, disease resistance, and improved agronomic quality.
Innovation Solution
The introduction of soybean cultivar SG4377NRR, which is resistant to glyphosate herbicides and has high yield potential, along with methods such as selfing, backcrossing, and genetic engineering to produce plants with superior characteristics like herbicide resistance, disease resistance, and improved nutritional quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used to develop new soybean cultivars, then desirable traits such as disease resistance and yield can be achieved, but the process becomes time-consuming and unpredictable
Solution Approach 1:
The patent replaces conventional mechanical breeding methods (crossing, selfing, and selection) with genetic engineering techniques. Specifically, glyphosate resistance is introduced through direct genetic modification rather than traditional crossing and selection, dramatically reducing the time required to develop cultivars with desirable traits while increasing predictability of the outcome
Solution Approach 2:
The patent changes the fundamental parameter of trait introduction from phenotypic selection in conventional breeding to direct genotypic modification. By introducing the glyphosate resistance gene directly through genetic engineering, the breeding process achieves precise control over trait inheritance, eliminating the unpredictability and time constraints of traditional methods
2Reliability
If extensive breeding programs are implemented to achieve superior traits, then cultivar quality improves, but research costs and resource expenditure increase
Solution Approach 1:
The patent replaces resource-intensive conventional breeding programs with efficient genetic engineering approaches. By directly introducing the glyphosate resistance trait through genetic modification rather than conducting multiple generations of crossing and selection, the research time and resource costs are significantly reduced while maintaining high agronomic quality
Solution Approach 2:
The patent performs the trait introduction in advance through direct genetic engineering, eliminating the need for lengthy breeding programs. The glyphosate resistance is incorporated into the cultivar genome directly, allowing researchers to skip multiple generations of selection and evaluation that would otherwise be required
