Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding soybean varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, and often result in varieties that are not easily replicable.
Innovation Solution
The development of the soybean variety 01051603, which incorporates specific genetic traits through cross-breeding and genetic transformation, including the introduction of transgenic genes for herbicide resistance, disease resistance, and improved nutritional quality, and the use of advanced breeding techniques like backcrossing and marker-assisted selection to produce consistent and superior soybean lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used, then soybean varieties can be developed with desirable traits, but the process is time-consuming and unpredictable
Solution Approach 1:
The patent replaces conventional mechanical breeding methods (manual crossing, selection, and phenotypic evaluation) with molecular marker-based genetic analysis. By using DNA markers linked to desirable traits, breeders can predict trait inheritance with high accuracy without waiting for phenotypic expression, dramatically reducing breeding cycle time and improving reliability.
Solution Approach 2:
The patent introduces molecular markers as intermediaries between genes and phenotypic traits. These markers serve as detectable proxies for desirable traits, allowing breeders to screen for trait presence at the DNA level rather than waiting for physical expression, thereby accelerating the breeding process while maintaining accuracy.
2Stability of the object's composition
If conventional breeding techniques are used, then soybean varieties can be developed, but the results are not easily replicable
Solution Approach 1:
The patent replaces phenotypic selection with genotypic selection using molecular markers. This substitution ensures that selected plants possess the desired genetic composition regardless of environmental variations, making variety composition stable and results easily replicable across different locations and seasons while maintaining high breeding efficiency.
Solution Approach 2:
The patent implements molecular marker-based feedback mechanisms where DNA analysis results directly inform breeding decisions. This feedback loop ensures that only plants with the correct genetic makeup advance to the next breeding stage, guaranteeing variety consistency and enabling precise replication of successful breeding outcomes.
3Reliability
If transgenic genes are introduced for herbicide resistance and disease resistance, then agronomic quality is improved, but genetic complexity increases
Solution Approach 1:
The patent extracts and isolates specific resistance genes and their associated molecular markers from donor parents. By focusing on individual resistance traits rather than whole-genome transfers, the complexity is managed through targeted gene introduction while achieving reliable disease and pest resistance in the soybean variety.
Solution Approach 2:
The patent applies local quality by introducing specific resistance genes at particular genomic locations rather than uniform genetic modification throughout the genome. This targeted approach allows the soybean to gain specific resistance traits (herbicide and disease resistance) while maintaining the natural complexity of the rest of the genome, thereby improving reliability without excessive overall genetic complexity.
