Innovation Solution
The development of the soybean variety 01098259, which includes specific genetic modifications and locus conversions for traits like herbicide resistance, disease resistance, and improved agronomic characteristics through backcrossing and genetic transformation techniques, allowing for the introduction of desired traits while maintaining the original variety's morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity and trait combinations can be explored, but the process requires extensive research and time due to unpredictability of genetic combinations
Solution Approach 1:
The patent applies preliminary action by using molecular markers to identify and select plants with desired traits before actual breeding occurs. This allows breeders to pre-screen large populations for specific genetic combinations, significantly reducing the time required to develop new varieties while maintaining genetic diversity. The marker-assisted selection process enables early identification of promising candidates without waiting for phenotypic expression.
Solution Approach 2:
The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based genetic analysis. Instead of visually screening plants for traits and making selections based on physical characteristics, the invention uses DNA markers to directly detect and select for desired genetic combinations, accelerating the breeding process while preserving adaptability.
2Productivity
If molecular marker-assisted selection is implemented to accelerate breeding, then breeding efficiency and trait prediction accuracy improve, but the complexity of the breeding program and cost increase
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: initial population development, molecular marker screening, selected plant propagation, and final variety development. This segmentation allows the complex process to be managed in manageable stages, with molecular markers applied at specific decision points rather than continuously, reducing overall program complexity while maintaining high breeding efficiency.
3Manufacturing precision
If backcrossing is used to introduce specific traits while maintaining variety characteristics, then trait introduction precision improves, but the number of generations required and time increase
Solution Approach 1:
The patent applies preliminary action by using molecular markers to identify the desired trait early in the backcrossing process and to track its inheritance through generations. This allows breeders to make informed decisions at each backcross generation, potentially reducing the number of backcrosses needed while ensuring precise trait introduction and maintaining the original variety's characteristics.
