Innovation Solution
The development of the soybean variety XB52K13, which is the result of careful breeding and selection, combining traits such as resistance to diseases, insects, drought, and improved agronomic characteristics, with methods for producing and characterizing seeds, cells, and plants of this variety, including introgression of transgenic or mutant traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding processes are used to combine multiple desirable traits, then disease resistance and yield improvement are achieved, but the breeding process becomes extremely time-consuming and resource-intensive
Solution Approach 1:
The patent segments the complex breeding process into distinct generations (P, F1, F2, F3, F4) with specific selection criteria for each stage. This systematic segmentation allows efficient tracking and combination of multiple traits across generations, reducing the overall time required while maintaining reliability of disease resistance and yield improvements.
Solution Approach 2:
The patent applies preliminary action by pre-selecting parental lines with specific desirable traits (disease resistance, yield potential) before initiating the cross-breeding program. This preliminary selection of germplasm with known favorable characteristics accelerates the breeding process by ensuring that subsequent generations inherit these traits more predictably, reducing the time needed to achieve reliable disease resistance.
2Stability of the object's composition
If multiple generations of selection and crossing are performed to achieve stable varieties, then trait stability and uniformity are improved, but the time required from first cross to finished seed delivery increases
Solution Approach 1:
The patent implements feedback mechanisms at each generation stage where selected plants are evaluated for trait stability and uniformity. This feedback loop allows breeders to identify and eliminate off-type plants early, ensuring that only stable, uniform individuals progress to the next generation. This maintains high trait stability while optimizing the number of generations required, thereby improving variety development speed.
Solution Approach 2:
The patent changes key parameters at each generation stage, such as selection intensity, population size, and evaluation criteria. By adjusting these parameters systematically across generations, the patent achieves stable trait composition more efficiently, reducing the total time from first cross to finished seed delivery while maintaining the required level of stability and uniformity.
3Manufacturing precision
If careful breeding and selection are conducted to combine multiple desirable traits, then the quality and agronomic characteristics of the variety are improved, but the resource requirements and complexity of the breeding program increase
Solution Approach 1:
The patent segments the complex trait combination process into discrete generational stages, each with specific selection objectives. This segmentation breaks down the overall complexity into manageable steps, allowing breeders to focus on combining specific traits at each generation rather than attempting to manage all traits simultaneously, thereby improving trait combination accuracy while reducing perceived program complexity.
Solution Approach 2:
The patent applies local quality by assigning different selection priorities and criteria to different generations and trait types. For example, early generations may focus on disease resistance while later generations emphasize yield and agronomic characteristics. This localized approach to quality control improves the accuracy of trait combination by addressing specific quality requirements at appropriate stages, while simplifying the overall breeding program structure.
