Engineering Contradiction Analysis
1Reliability
If traditional soybean variety development methods are used, then desirable traits can be combined in a single variety, but the process takes 6-12 years and requires precise planning with minimal directional changes
Solution Approach 1:
The patent applies preliminary action by developing and maintaining a pre-characterized, stable, and homozygous soybean variety (5PESH71) with known genetic traits before breeding operations begin. This pre-prepared genetic base allows breeders to immediately start crossing programs without the typical 6-12 year development timeline, as the foundation variety is already optimized and ready for trait combination.
Solution Approach 2:
The patent utilizes parameter changes by transforming the soybean variety through genetic modification to introduce specific traits (such as herbicide resistance, disease resistance, or improved yield characteristics) into the stable 5PESH71 background. This allows rapid alteration of genetic parameters without requiring traditional multi-generational breeding, significantly reducing the time to combine desirable traits.
2Stability of the object's composition
If soybean variety 5PESH71 is used as a stable and homozygous base, then uniformity and stability across traits are achieved, but additional methods are required for crossing, introgressing traits, and characterizing plants
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct, manageable modules: (1) using the stable 5PESH71 variety as a fixed base, (2) performing targeted crossings with specific donor varieties, (3) introgressing individual traits through backcrossing, and (4) characterizing resulting plants. This modular approach simplifies the overall complexity by breaking down the breeding program into standardized, repeatable steps.
Solution Approach 2:
The patent uses molecular markers as intermediaries to facilitate trait introgression and plant characterization. These markers serve as mediators that allow breeders to track and select for specific traits during crossing and backcrossing operations, simplifying the complexity of managing multiple breeding steps while maintaining the stability of the 5PESH71 genetic background.
