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 inefficient and directionally unstable, taking six to twelve years from the first cross to delivering finished seed.
Innovation Solution
The introduction of soybean variety 5PGWK31, which is self-pollinated to ensure homozygosity and phenotypic stability, along with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to produce stable, high-yielding soybeans with improved agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the variety achieves high yield and disease resistance, but the development process takes six to twelve 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 crossing. This advance preparation of genetically superior parents with known performance characteristics accelerates the breeding process while ensuring the resulting variety achieves the desired reliability in yield and disease resistance.
2Stability of the object's composition
If multiple crossing and selection steps are performed to achieve trait combination, then the variety achieves phenotypic stability and uniformity, but the process becomes complex and resource-intensive
Solution Approach 1:
The patent employs feedback mechanisms through systematic evaluation and characterization of breeding lines at multiple stages. Performance data from field trials, disease resistance assessments, and yield measurements are used to guide subsequent crossing decisions and selection processes. This feedback-driven approach achieves phenotypic stability and uniformity while reducing unnecessary complexity by focusing resources on the most promising lines.
3Productivity
If traditional breeding methods are used without precise planning, then the breeding process can proceed with minimal resources, but directionality is lost and development time increases
Solution Approach 1:
The patent applies preliminary action through comprehensive pre-breeding planning that defines specific breeding objectives, selects parent lines with known superior traits, and establishes evaluation protocols before the breeding process begins. This advance planning creates directional focus that accelerates productivity while reducing the time required to deliver finished seed by avoiding later course corrections.
Solution Approach 2:
The patent implements self-service through the development of self-pollinating soybean lines that maintain their genetic integrity without requiring complex manual intervention for controlled pollination. This self-service characteristic reduces labor requirements and increases breeding efficiency while maintaining precise directional control over trait combination.
