Soybean Variety 5PLSB92 Breeding Stability
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 tolerance to environmental stresses, while existing methods are inefficient and directionally unstable.
Innovation Solution
The introduction of soybean variety 5PLSB92, which is stable and homozygous, combined with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to produce plants with improved agronomic characteristics and disease resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the variety 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-characterizing variety 5PLSB92 with multiple desirable traits (high yield, disease resistance, stress tolerance) before using it as a parent in breeding programs. This pre-prepared genetic foundation eliminates the need for time-consuming trait combination experiments, directly reducing the 6-12 year development timeline while maintaining reliability of desired traits
2Productivity
If multiple crossing and selection steps are performed to achieve stable high-yielding varieties, then the variety shows maximal yield over different conditions, but the process requires precise planning and efficient resource use with minimum changes in direction
Solution Approach 1:
The patent applies parameter changes by providing a variety (5PLSB92) with already-optimized genetic parameters for yield, disease resistance, and stress tolerance. Using this pre-optimized parent in crossing programs reduces the complexity of multiple selection steps needed to achieve stable high-yielding varieties, as the desirable trait combinations are already established in the parent variety
