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, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to the need for innovative approaches to introduce specific traits like herbicide resistance and improved agronomic characteristics.
Innovation Solution
The development of the soybean variety D5789653, which includes methods for crossing and breeding to introduce specific traits like herbicide resistance, disease resistance, and improved nutritional quality through genetic transformation and backcrossing, allowing for the recovery of desired morphological and physiological characteristics along with single locus conversions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties with desirable traits, then the varieties can achieve stable inheritance of traits, but the breeding process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by performing genetic transformation to introduce desired traits directly into the soybean genome before conventional breeding begins. This allows the breeder to start with plants that already possess the target traits (such as herbicide resistance or disease resistance), eliminating the need for lengthy selective breeding to introduce these traits. The transformation step prepares the genetic material in advance, making subsequent breeding operations more efficient and predictable.
2Reliability
If conventional breeding techniques are used to combine multiple desirable traits, then the traits can be stably inherited, but the process becomes unpredictable in achieving the desired trait combination
Solution Approach 1:
The patent uses preliminary action by pre-combining multiple desirable traits through genetic transformation in the parental lines before crossing. This ensures that when the cross is made, the offspring already have a high probability of inheriting the desired trait combination, making the breeding process more predictable and efficient.
Solution Approach 2:
The patent employs molecular markers as intermediaries to track and select for desired traits during breeding. These markers serve as reliable indicators that allow breeders to efficiently identify plants with the desired trait combinations without having to wait for phenotypic expression, thereby improving both reliability and productivity.
3Productivity
If genetic transformation is used to introduce specific traits, then the breeding process becomes more predictable and efficient, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct modular steps: genetic transformation to introduce specific traits, followed by conventional crossing and selection. This modular approach allows each step to be optimized independently and makes the overall complex process more manageable and systematic.
Solution Approach 2:
The patent uses molecular markers as intermediaries to simplify the management of complexity. These markers provide clear, objective criteria for selecting plants with desired traits, replacing subjective phenotypic assessments and reducing the overall complexity of trait tracking and selection in the breeding program.
4Reliability
If backcrossing is used to recover parental characteristics, then the desired morphological and physiological traits can be recovered, but multiple generations are required increasing the time investment
Solution Approach 1:
The patent applies preliminary action by performing genetic transformation to introduce desired traits into the parental line before backcrossing begins. This ensures that the trait of interest is already present in the parental genome, so during backcrossing, the breeder can more efficiently recover the parental background while retaining the transformed trait, reducing the number of generations needed compared to introducing the trait during backcrossing.
Solution Approach 2:
The patent uses molecular markers as intermediaries to accelerate the backcrossing process by enabling marker-assisted selection. This allows breeders to quickly identify and select offspring that have both the desired parental background and the transformed trait, significantly reducing the time required to recover parental characteristics compared to traditional phenotypic selection methods.
