Problem
Soybean breeding faces challenges in predicting phenotypic expression due to genetic complexity and environmental factors, making it difficult to replicate varieties using the same parents and methodology, resulting in unique and unpredictable outcomes.
Innovation Solution
Development of the soybean variety DLL1172, which can be used for self-pollination, backcrosses, and hybrid production, incorporating transgenes for traits like herbicide resistance, disease resistance, and nutritional enhancement through genetic engineering and tissue culture methods, allowing for the creation of stable and uniform soybean plants with desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used with the same parents and methodology, then breeding process is simple and cost-effective, but phenotypic expression is unpredictable and variety replication is difficult
Solution Approach 1:
The patent uses molecular markers to create a genetic copy of the target variety's DNA profile. By identifying and tracking specific marker combinations that define the desired variety, breeders can reliably replicate the variety's genetic identity across different breeding cycles and locations, ensuring consistent phenotypic expression regardless of environmental variations.
Solution Approach 2:
The patent implements a feedback mechanism where molecular markers provide real-time information about the genetic composition of breeding progeny. This allows breeders to select plants with the desired genetic makeup based on marker presence, creating a closed-loop system that ensures accurate variety replication and enables informed breeding decisions.
2Measurement precision
If molecular marker technology is implemented for variety replication, then phenotypic prediction accuracy improves, but breeding process complexity and cost increase
Solution Approach 1:
The patent extracts specific molecular markers from the complex genome that are directly associated with desired phenotypic traits. By focusing only on these key markers rather than analyzing the entire genome, the method achieves high prediction accuracy while simplifying the breeding process and reducing costs through targeted genetic analysis.
Solution Approach 2:
The patent changes the measurement parameter from observable phenotypic traits to molecular marker presence/absence. This parameter transformation enables more precise genetic prediction because markers provide direct information about genotype, eliminating the environmental noise that affects phenotypic expression and improving prediction reliability.
3Stability of the object's composition
If extensive testing and selection are performed to ensure variety uniformity, then variety stability improves, but breeding time and resource requirements increase
Solution Approach 1:
The patent performs preliminary genetic screening using molecular markers at early breeding stages, before plants are fully grown. This allows breeders to identify and eliminate unwanted genetic variants early in the process, ensuring variety uniformity without requiring extensive field testing and selection across multiple growing seasons.
