Soybean Germplasm Breeding With Marker-Assisted Trait Introgression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is unpredictable and requires intensive research due to vast genetic diversity and complex traits, making it challenging to produce consistent and commercially viable soybean germplasm with desired characteristics such as disease resistance, insect resistance, and altered oil profiles.
Innovation Solution
The introduction of transgenic genes and single locus conversions in soybean varieties CL1945910, CL1945851, CL1924220, CL1924371, CL1946032, CL1946267, CL1946273, CL1946369, CL1946309, CL1946320, CL1946388, and/or CL1946410, CL1946167, which confer traits like herbicide resistance, fungal resistance, insect resistance, and altered oil profiles, along with breeding methods like marker-assisted selection and backcrossing to achieve desired genetic combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop new soybean cultivars, then genetic diversity and complexity are maintained, but the process becomes unpredictable and time-consuming
Solution Approach 1:
The patent applies preliminary action by using marker-assisted selection to identify and select plants with desired traits before completing the full breeding cycle. Molecular markers are used to predict the presence of desirable genes (such as disease resistance, insect resistance, or altered oil profiles) early in the breeding process, allowing breeders to make informed selections without waiting for phenotypic expression, thereby reducing the time required to develop new cultivars while improving predictability.
2Manufacturing precision
If marker-assisted selection is employed to introduce desired traits, then breeding precision is improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent uses molecular markers as intermediaries between the desired traits and the breeding process. These markers serve as detectable proxies for the actual genes of interest, allowing breeders to select plants based on marker presence rather than directly observing the trait. This intermediary approach enables precise trait introduction through DNA-based selection while managing complexity by providing clear, objective criteria for selection decisions.
3Manufacturing precision
If backcrossing is used to transfer specific genes, then the desired traits are achieved with higher accuracy, but the number of generations required increases
Solution Approach 1:
The patent applies preliminary action by using molecular markers to identify and select plants with the desired backcrossing traits early in the process. Instead of waiting for multiple generations for phenotypic expression, markers allow breeders to identify plants carrying the desired genes immediately after the backcross, enabling accelerated selection and reducing the number of generations required to achieve accurate trait transfer.
