Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is a time-consuming process that requires precise planning and resource management, aiming to combine desirable traits such as high seed yield, disease resistance, drought tolerance, and improved fatty acid profiles, while existing methods are inefficient in achieving these goals.
Innovation Solution
The introduction of soybean cultivar S170042, which is developed through crossing and mutagenesis, incorporating traits like resistance to glyphosate and glufosinate herbicides, and disease resistance, along with methods for introgressing transgenic or mutant traits, enabling the creation of superior soybean hybrids and variants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the cultivar achieves improved yield and resistance traits, but the development process becomes extremely time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-characterizing multiple soybean accessions for specific traits (fatty acid profiles, resistance genes, yield components) before breeding. This advance characterization allows breeders to select parents with known desirable traits, eliminating the need for lengthy trial-and-error breeding cycles and directly reducing the 6-12 year development timeline while maintaining trait stability
2Adaptability or versatility
If multiple desirable traits are combined in a single cultivar, then the overall cultivar performance is improved, but the breeding program complexity increases significantly
Solution Approach 1:
The patent segments the breeding program into distinct modules: (1) identifying accessions with specific target traits through preliminary characterization, (2) selecting parental combinations based on complementary trait profiles, (3) executing targeted crosses, and (4) evaluating progeny for desired trait combinations. This segmentation transforms a complex monolithic breeding program into manageable steps, reducing overall program complexity while achieving multi-trait cultivars
3Productivity
If resource allocation is optimized for efficient breeding, then the breeding process becomes more manageable, but the quality and quantity of desirable traits that can be combined are limited
Solution Approach 1:
The patent creates a universal preliminary characterization framework that evaluates multiple accessions simultaneously for diverse traits including fatty acid composition, disease resistance, insect resistance, and yield components. This multi-functional assessment system allows a single breeding program to pursue multiple trait combinations using the same core resources, thereby maintaining high productivity while expanding trait combination diversity
