Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in soybean breeding is to develop stable, high-yielding varieties that are resistant to diseases, insects, and abiotic stresses, while also improving fatty acid profiles and agronomic characteristics, which is a time-consuming process requiring precise planning and resource management.
Innovation Solution
The development of the soybean variety XB31S10, which combines desirable traits such as resistance to aerial blight, brown stem rot, and improved fatty acid composition, achieved through careful breeding and selection, allowing for the production of seeds with enhanced agronomic and nutritional qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to develop varieties with multiple desirable traits, then disease resistance and fatty acid profile improvement are achieved, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits (disease resistance, fatty acid profiles) before crossing. The parental soybean plants are screened and evaluated for resistance to multiple diseases and insects, and for improved fatty acid composition, ensuring that the desired traits are present in the parent generation before hybridization occurs. This preliminary selection and characterization of parental material accelerates the breeding process by avoiding generations of selection that would otherwise be required.
2Stability of the object's composition
If multiple generations of selection and crossing are performed to combine desirable traits, then uniformity and stability of traits are improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct functional modules: (1) selection of parental lines with specific trait combinations, (2) controlled crossing to produce F1 hybrids, (3) evaluation of F1 and subsequent generations for trait expression, and (4) selection and stabilization of superior lines. This modular segmentation of the breeding process allows for systematic management of complexity while achieving uniform and stable trait expression in the final varieties.
3Productivity
If extensive phenotypic evaluation and trait analysis are conducted, then the quality and agronomic performance of the variety are improved, but the resources and time required for evaluation increase
Solution Approach 1:
The patent applies preliminary action by conducting preliminary phenotypic evaluation and characterization of parental lines for key agronomic traits including yield potential, disease resistance, and fatty acid composition before crossing. This preliminary assessment allows breeders to select parental combinations most likely to produce high-performing hybrids, reducing the need for extensive resource投入 in later evaluation stages while still achieving superior grain yield and quality in the final variety.
