Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, due to the unpredictability of genetic combinations and the need for extensive research and resources.
Innovation Solution
The development of the soybean variety 01045783, which combines desirable traits through a specific breeding history and genetic transformation, including the introduction of a transgenic gene for glyphosate tolerance, and the use of backcrossing and genetic marker-assisted selection to introduce desired traits while maintaining the variety's morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional soybean breeding methods are used, then basic variety development is achieved, but the development of stable, high-yielding varieties with multiple desirable traits is difficult and resource-intensive
Solution Approach 1:
The patent applies preliminary action by using genetic marker-assisted selection to identify and select plants with desired traits before completing the full breeding cycle. This allows the breeding program to focus resources on promising lines that have already been pre-screened for key characteristics such as disease resistance, drought tolerance, and yield potential, thereby reducing the overall complexity and resource requirements of the breeding program while maintaining variety stability.
Solution Approach 2:
The patent uses genetic markers as intermediaries between the breeding objectives and the actual plant selection process. These markers serve as detectable indicators of desired traits, allowing breeders to indirectly select for complex phenotypic characteristics through molecular detection, thus simplifying the breeding program structure and reducing the need for extensive phenotypic evaluation and resource consumption.
2Productivity
If extensive breeding programs are conducted to combine multiple desirable traits, then variety improvement is achieved, but research and development resources are significantly increased
Solution Approach 1:
The patent replaces traditional mechanical phenotypic evaluation methods with molecular genetic marker detection. Instead of requiring extensive field testing, visual inspection, and multiple generations of breeding to identify desired traits, the system uses molecular markers to directly detect and select for genetic configurations associated with high yield, disease resistance, and other desirable traits. This substitution dramatically reduces the time and resources required for breeding while maintaining or improving productivity.
Solution Approach 2:
The patent changes the detection parameter from phenotypic characteristics (requiring growth and environmental interaction) to genotypic markers (detectable at the molecular level). This parameter change allows for earlier and more efficient selection of high-yielding lines, reducing the breeding cycle time and resource requirements while maintaining focus on achieving high productivity through combination of desirable traits.
3Adaptability or versatility
If traditional breeding methods are used without genetic transformation, then natural variation is utilized, but desirable traits such as disease resistance and drought tolerance are difficult to introduce
Solution Approach 1:
The patent uses genetic markers as intermediaries to track and select for disease resistance and drought tolerance traits that may be difficult to express or select for directly. These markers serve as detectable proxies for complex adaptive traits, allowing breeders to efficiently introduce and maintain desirable characteristics without requiring extensive trial-and-error breeding, thus simplifying the process while enhancing adaptability.
Solution Approach 2:
The patent applies preliminary action by pre-introducing desirable traits through genetic transformation before the main breeding program begins. This allows the variety to start with built-in disease resistance and drought tolerance mechanisms, reducing the need for subsequent breeding steps to achieve these characteristics and simplifying the overall breeding process while maintaining high adaptability.
