Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of stable, high-yielding soybean varieties that are agronomically sound and possess desirable traits such as disease resistance, drought tolerance, and improved compositional traits is a time-consuming process requiring precise planning and resource efficiency, with existing methods taking six to twelve years from cross to delivery.
Innovation Solution
The introduction of the novel soybean variety 5PSAC37, which combines desirable traits like resistance to diseases, insects, and tolerance to drought and heat, along with improved agronomic characteristics, through a combination of genetic manipulation and breeding techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop new soybean varieties, then the variety can be developed with desirable traits, but the process takes six to twelve years which is time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-establishing a structured breeding program with defined objectives, selecting germplasm with desirable traits before the actual crossing begins, and planning multiple steps (crossing, selection, evaluation) in advance. This organized preliminary planning enables the variety development to proceed efficiently through the subsequent generations, reducing the overall six to twelve year timeline while maintaining the reliability of combining desirable traits.
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the variety becomes more versatile and reliable, but the breeding process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct manageable steps: (1) analyzing and defining problems and weaknesses of current germplasm, (2) establishing program goals, (3) selecting germplasm with specific traits, (4) crossing selected lines, (5) evaluating progeny, and (6) releasing varieties. This segmentation allows complex multi-trait combination to be handled systematically through organized generations of crossing and selection, reducing the perceived complexity while achieving versatile trait combinations.
Solution Approach 2:
The patent applies universality by developing a breeding program framework that can be universally applied to combine multiple desirable traits (disease resistance, insect resistance, drought tolerance, heat tolerance, yield improvement, compositional traits) in a single variety. The standardized multi-step approach serves multiple functions: it manages complexity, ensures trait combination reliability, and can be adapted to different trait combinations, making the breeding process itself universal rather than requiring separate complex procedures for each trait combination.
3Reliability
If stable and high yielding varieties are developed, then the variety performs reliably across different conditions, but the development requires precise planning and efficient resource use
Solution Approach 1:
The patent applies feedback by incorporating evaluation steps at multiple generations where progeny are assessed for yield stability, disease resistance, and other desirable traits. Based on this feedback, breeders can identify which lines perform reliably across different conditions and focus resources on those lines for further development. This feedback mechanism ensures yield stability while allowing efficient resource allocation by eliminating unpromising lines early in the process.
