Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding soybean varieties that combine desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, while also being susceptible to herbicides and pests, and require extensive resources and time due to the unpredictability of genetic combinations.
Innovation Solution
The development of the soybean variety D2011903, which includes a single locus conversion that can introduce traits like herbicide resistance, insect resistance, and improved nutritional quality through genetic transformation, and a breeding program that utilizes techniques like backcrossing and marker-assisted selection to produce hybrid seeds and plants with specific agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to combine desirable traits, then genetic diversity is achieved, but the process requires extensive resources and time due to unpredictability of genetic combinations
Solution Approach 1:
The patent applies parameter changes by utilizing marker-assisted selection to monitor and control specific genetic parameters during breeding. This allows breeders to track the inheritance of desirable traits through molecular markers, transforming the unpredictable genetic combination process into a controlled parameter-based selection system that reduces time and resource requirements
Solution Approach 2:
The patent implements feedback mechanisms through the use of molecular markers that provide real-time information about the genetic composition of breeding lines. This feedback allows breeders to make informed decisions about which plants to advance or discard, eliminating the need for lengthy field testing and significantly reducing the breeding cycle time while maintaining genetic diversity
2Adaptability or versatility
If multiple traits are combined in a single variety, then agronomic quality is improved, but the breeding complexity increases
Solution Approach 1:
The patent applies segmentation by breaking down the complex task of combining multiple traits into manageable segments through the use of specific molecular markers for each trait. Each marker tracks a specific genetic locus, allowing breeders to independently monitor and combine different traits (such as disease resistance, yield, and quality) without being overwhelmed by the overall complexity
Solution Approach 2:
The patent implements universality through the use of a standardized marker-assisted selection system that can be applied across multiple breeding programs and trait combinations. The same molecular marker technology and methodology can simultaneously track multiple different traits, reducing the need for separate breeding programs for each trait and simplifying the overall breeding complexity
