Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean varieties is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as high yield, disease resistance, and environmental tolerance, while existing methods are slow and prone to directional changes.
Innovation Solution
The introduction of soybean variety 5PKPS94, which is stable and homozygous, combined with methods for crossing, introgressing transgenic or mutant traits, and characterizing plants to produce varieties with improved agronomic characteristics, such as resistance to diseases and environmental stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to develop new varieties with multiple desirable traits, then the varieties can achieve high yield and disease resistance, but the development process takes 6-12 years and requires extensive resources
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parent lines with specific desirable traits (high yield, disease resistance, stress tolerance) before initiating the breeding program. This advance preparation of germplasm with known characteristics accelerates the breeding process while ensuring the final variety meets target performance criteria.
Solution Approach 2:
The patent implements feedback mechanisms through systematic evaluation and characterization of breeding progeny at multiple stages. Performance data on yield, disease resistance, and other traits are collected and used to guide selection decisions, allowing the breeding program to efficiently identify superior lines and adjust strategies based on observed results.
2Adaptability or versatility
If multiple crossing and selection steps are performed to combine desirable traits, then the final variety achieves improved agronomic characteristics, but the process becomes complex and prone to directional changes
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: parent line selection, controlled crossing, progeny evaluation, and variety development. Each phase has specific objectives and selection criteria, allowing complex trait combination to be managed through systematic, stepwise progression rather than simultaneous manipulation of multiple variables.
Solution Approach 2:
The patent employs universal parent lines and standardized evaluation protocols that can be applied across different breeding programs and trait combinations. This multi-functional approach allows the same methodological framework to be used for combining various desirable traits (yield, disease resistance, stress tolerance) without requiring program-specific modifications.
