Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding 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, leading to the need for innovative approaches to combine multiple desirable characteristics in a single variety.
Innovation Solution
The development of the soybean variety A1036445, which involves crossing and selecting plants to combine traits like disease resistance, herbicide tolerance, and improved nutritional quality, using techniques like backcrossing and genetic transformation to introduce specific loci, enabling the creation of hybrid seeds and plants with enhanced agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional breeding techniques are used to develop soybean varieties, then the breeding process is simple and requires minimal specialized equipment, but the development time is excessively long and the predictability of desirable traits is low
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits (disease resistance, yield potential, nutritional quality) before crossing. This preliminary characterization and selection of parents with known genetic profiles enables more predictable outcomes and reduces the time required for subsequent breeding cycles, as the foundational genetic material is already optimized for the desired traits.
Solution Approach 2:
The patent implements feedback mechanisms through systematic evaluation and selection processes at multiple stages of breeding. Performance data from field trials, disease resistance assays, and compositional analysis are used to feed back into selection decisions for subsequent generations. This feedback loop allows breeders to make informed decisions that accelerate variety development while maintaining predictability of desirable traits.
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the overall agronomic performance and nutritional quality improve, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct modules: selecting parents for specific traits (e.g., disease resistance in one parent, yield in another), performing targeted crosses, and evaluating progeny for individual and combined traits. This modular approach allows parallel development of different trait combinations and reduces overall development time compared to attempting to combine all traits in a single undifferentiated breeding process.
Solution Approach 2:
The patent merges desirable traits from multiple parental lines into a single soybean variety through controlled crossing and selection. By combining parents with complementary traits (e.g., one parent with disease resistance and another with high yield), the patent achieves varieties that simultaneously express multiple desirable characteristics, improving overall agronomic performance and nutritional quality while managing breeding complexity through systematic trait integration.
3Manufacturing precision
If advanced genetic techniques like genetic transformation are used, then the precision and efficiency of introducing specific traits improve, but the complexity of the breeding process and regulatory requirements increase
Solution Approach 1:
The patent uses conventional crossbreeding and selection as an intermediary approach to achieve trait introduction without directly applying complex genetic transformation techniques. By using carefully selected parental lines with desired traits and employing systematic crossing and selection protocols, the patent achieves precise trait integration through biological mediation rather than direct genetic engineering, thereby reducing regulatory and procedural complexity while maintaining precision in trait introduction.
