Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits like disease resistance, drought tolerance, and improved fatty acid profiles, but face challenges in efficiently combining these traits in a single variety.
Innovation Solution
Development of the soybean variety XBP48011, which is the result of careful breeding and selection, combining traits such as resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, through a comprehensive breeding program involving cross-pollination and genetic marker-assisted selection.
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 variety can achieve improved yield, disease resistance, and stress tolerance, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-establishing a comprehensive set of genetic markers and selection criteria before the breeding process begins. The breeding program pre-defines the desired traits (disease resistance, stress tolerance, yield characteristics) and prepares the genetic framework through controlled crosses and marker development, enabling more efficient trait combination in subsequent generations without requiring years of trial-and-error breeding
Solution Approach 2:
The patent implements feedback mechanisms through molecular marker-assisted selection, where genetic markers provide real-time information about trait inheritance. This feedback loop allows breeders to monitor and select for desired traits at the molecular level, accelerating the breeding process by eliminating the need for lengthy phenotypic evaluation and reducing the time required to achieve variety stability
2Adaptability or versatility
If multiple desirable traits are combined in a single soybean variety through traditional breeding, then the variety achieves improved agronomic performance, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into distinct, manageable modules: (1) parental line development with specific traits, (2) controlled cross-pollination protocols, (3) molecular marker-based selection stages, and (4) multi-environment testing phases. This segmentation allows each trait combination step to be optimized independently while maintaining overall program coherence
Solution Approach 2:
The patent uses molecular markers as intermediaries between the desired traits and the breeding process. These markers serve as detectable proxies for complex traits like disease resistance and stress tolerance, simplifying the selection process by providing objective, measurable indicators that can be screened efficiently without requiring complex phenotypic analysis for each trait
