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 efforts and is difficult to predict due to complexity of genetic combinations and environmental factors
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with known desirable traits and using molecular markers to identify specific genetic loci before crossing. This preliminary characterization of parental germplasm and target traits allows the breeding program to proceed more efficiently with predictable outcomes, reducing the extensive trial-and-error time required in conventional breeding.
Solution Approach 2:
The patent implements feedback through molecular marker-assisted selection during the breeding process. By continuously monitoring specific genetic markers associated with desired traits (such as disease resistance and yield components), breeders can make informed decisions about which progeny to advance, providing real-time feedback on genetic progress and reducing the time needed to develop varieties with target trait combinations.
2Reliability
If multiple traits are combined in a single soybean variety through breeding, then agronomic quality and resistance to diseases and insects are improved, but the device complexity and breeding program complexity increase
Solution Approach 1:
The patent applies segmentation by breaking down the complex task of combining multiple traits into manageable segments: (1) selecting parental lines with specific single or double traits, (2) performing targeted crosses between these parents, (3) using molecular markers to track inheritance of specific trait loci, and (4) selecting progeny that inherit the desired combination. This segmented approach reduces breeding program complexity compared to attempting to improve all traits simultaneously in a single population.
Solution Approach 2:
The patent applies local quality by focusing breeding efforts on specific genetic loci associated with particular traits rather than attempting to improve the entire genome uniformly. Molecular markers allow breeders to concentrate selection pressure on specific chromosomal regions containing genes for disease resistance, yield, or other target traits, while maintaining the rest of the genome from elite parental lines.
3Productivity
If extensive breeding research is conducted to achieve stable high-yielding varieties, then seed yield and agronomic quality are maximized, but the cost and resources required for breeding increase
Solution Approach 1:
The patent applies mechanics substitution by replacing traditional phenotypic selection methods (which require growing and evaluating large numbers of plants in field trials) with molecular marker-assisted selection. This substitution allows breeders to identify plants with desired genetic potential at the seedling stage or even before planting, eliminating the need for extensive field testing resources while still achieving high-yielding, stable varieties.
Solution Approach 2:
The patent applies parameter changes by shifting the selection criterion from phenotypic performance (which requires environmental control and large plot sizes) to genotypic markers. This parameter change from phenotype to genotype allows for more efficient resource utilization, as marker analysis can be performed on small tissue samples without requiring the plant to express the trait phenotypically, thereby reducing land, labor, and time resources needed for breeding evaluation.
