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 adaptability to various conditions, while existing methods are slow and prone to directional changes.
Innovation Solution
The introduction of soybean variety 5PKLM31, 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, then desirable traits such as disease resistance and adaptability can be combined, but the process takes 6-12 years and is time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-characterizing soybean variety 5PKLM31 for stable, homozygous traits including disease resistance and adaptability before using it as a parent in breeding programs. This pre-validation allows breeders to start with a known good genetic base, reducing the time needed for subsequent selection and testing phases while maintaining reliability of desirable traits
2Productivity
If traditional breeding methods are used to combine desirable traits, then high yield and disease resistance can be achieved, but the process requires numerous steps and is complex
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct modules: (1) using pre-characterized variety 5PKLM31 as a stable parent, (2) performing controlled crosses with specific donors, (3) selecting for desired traits, and (4) advancing generations systematically. This modular approach reduces overall process complexity while maintaining productivity by allowing parallel development of multiple breeding lines
3Stability of the object's composition
If traditional breeding methods are used to develop stable varieties, then yield consistency can be improved, but the process requires multiple generations and self-pollination steps
Solution Approach 1:
The patent applies preliminary action by providing variety 5PKLM31 that is already established as stable and homozygous for desirable traits. This pre-stabilized parent line reduces the number of generations needed in subsequent breeding programs to achieve yield consistency, as breeders start with genetically uniform material rather than developing stability from scratch
Solution Approach 2:
The patent applies copying by enabling breeders to replicate the successful genetic combination of variety 5PKLM31 across multiple breeding programs and environments. The stable, homozygous nature of 5PKLM31 allows its desirable traits to be consistently copied into new varieties through controlled crosses, reducing the time needed to achieve yield consistency in progeny
