Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean cultivar development is time-consuming and resource-intensive, aiming to combine desirable traits like higher seed yield, disease resistance, and improved fatty acid profiles, but existing methods are inefficient in achieving stable and uniform cultivars with desired characteristics.
Innovation Solution
Development of a new soybean cultivar S100108, involving breeding techniques such as backcrossing and genetic transformation to introduce transgenic traits for herbicide resistance, disease resistance, and improved agronomic qualities, along with tissue culture methods for regenerating plants with consistent physiological and morphological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine desirable traits in soybean cultivars, then the cultivar achieves improved yield and disease resistance, but the development process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-introducing disease resistance genes and desired traits through genetic transformation before conventional breeding begins. This allows the breeding program to start with genetically modified parents that already possess the target traits, eliminating the need for lengthy trait introduction phases and accelerating the overall breeding timeline while maintaining disease resistance.
Solution Approach 2:
The patent uses molecular markers as intermediaries to track and select for desired traits during breeding. These markers serve as proxies for complex disease resistance genes and yield-related traits, enabling breeders to efficiently identify and select plants carrying the desired genetic combinations without time-consuming phenotypic testing, thus resolving the contradiction between achieving reliable disease resistance and reducing breeding time.
2Stability of the object's composition
If multiple generations of crossing and selection are performed to achieve uniform cultivars, then the cultivar stability improves, but the productivity of the breeding program decreases
Solution Approach 1:
The patent replaces the mechanical system of repeated crossing and phenotypic selection with molecular marker-assisted selection. Instead of performing multiple generations of manual crossing and field evaluation to achieve uniformity, breeders use DNA markers to directly identify and select plants with the desired genetic composition in a single generation, dramatically increasing breeding productivity while ensuring cultivar stability and uniformity.
Solution Approach 2:
The patent changes the selection parameter from phenotypic traits (which require environmental expression and multiple generations to stabilize) to genotypic markers (which can be directly measured and selected). This parameter change allows for immediate selection of uniform genetic compositions without requiring multiple generations of crossing, thereby maintaining cultivar stability while significantly improving breeding productivity.
3Manufacturing precision
If extensive field trials and evaluations are conducted to ensure cultivar quality, then the agronomic quality improves, but the resource requirements increase
Solution Approach 1:
The patent applies preliminary action by conducting molecular marker screening and genetic analysis early in the breeding process, before extensive field trials. This preliminary genetic characterization allows breeders to identify and eliminate inferior lines early, reducing the number of plants that need to undergo resource-intensive field evaluations while still ensuring final cultivar quality and agronomic performance.
Solution Approach 2:
The patent uses molecular markers as intermediaries to predict agronomic quality traits without requiring extensive field trials. These markers serve as proxies for complex agronomic characteristics, enabling breeders to screen and select high-quality candidates in the laboratory setting, thereby reducing the need for large-scale field testing and minimizing resource consumption while maintaining manufacturing precision of agronomic quality.
