Innovation Solution
The development of the soybean variety A1024181, which includes methods for crossing and breeding to introduce specific traits like herbicide resistance, disease resistance, and improved nutritional quality through genetic transformation and backcrossing, allowing for the creation of hybrid seeds and plants with consistent physiological and morphological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties with desirable traits, then the breeding process is time-consuming and unpredictable, but the methods are simple and do not require complex genetic transformation procedures
Solution Approach 1:
The patent applies parameter changes by utilizing genetic transformation techniques to directly modify specific genes or gene combinations in soybean plants, rather than relying on conventional phenotypic selection. This allows precise control over trait inheritance patterns and accelerates the breeding cycle by skipping multiple generation steps, thereby improving predictability while reducing time loss.
Solution Approach 2:
The invention replaces the mechanical/conventional breeding system (manual crossing and phenotypic selection) with a molecular biology-based system (genetic transformation and molecular marker assistance). This substitution enables direct manipulation of genetic material to achieve desired traits more reliably and efficiently, resolving the contradiction between reliability and time loss.
2Reliability
If conventional breeding methods are used to combine desirable traits, then the process is straightforward, but it fails to consistently produce stable, high-yielding varieties with multiple desirable traits
Solution Approach 1:
The patent introduces molecular markers as intermediaries between the genetic transformation process and the selection of stable varieties. These markers serve as detectable indicators of specific gene presence or genotype, enabling precise tracking and selection of plants with desired traits throughout the breeding program, thereby ensuring stability while managing complexity through systematic tracking.
Solution Approach 2:
The invention employs a multi-functional breeding system that integrates genetic transformation, molecular marker analysis, and phenotypic evaluation into a unified approach. This universal system can simultaneously target multiple desirable traits (disease resistance, yield, quality) while maintaining stability, resolving the contradiction by consolidating multiple functions into a coordinated program rather than separate processes.
3Productivity
If genetic transformation and backcrossing are used to introduce specific traits, then the breeding process becomes more efficient and predictable, but the methods require complex laboratory procedures and expertise
Solution Approach 1:
The patent applies preliminary action by developing and validating molecular markers and transformation protocols before the actual breeding program begins. This preparation includes creating reference databases, establishing selection criteria, and pre-testing transformation efficiency, thereby simplifying the subsequent trait introduction process and improving productivity while reducing the operational difficulty through advance planning and standardized procedures.
