Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding soybean varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to genetic variability and environmental sensitivity.
Innovation Solution
The development of the soybean variety S110149, which combines improved traits through a breeding program involving crossing, selection, and genetic transformation, resulting in a stable variety suitable for mid-group 0 growing regions with specific characteristics like resistance to diseases, herbicides, and improved agronomic traits, and the use of tissue culture and regenerable cells to propagate and enhance the variety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties with desirable traits, then the breeding process is simple and accessible, but it is time-consuming and unpredictable, resulting in genetic variability and environmental sensitivity
Solution Approach 1:
The patent applies parameter changes by transitioning from conventional phenotypic selection to molecular marker-assisted selection, changing the selection parameter from observable traits to genetic markers. This enables earlier and more accurate selection of desirable traits, reducing breeding cycle duration while improving stability through controlled genetic inheritance patterns.
Solution Approach 2:
The patent replaces the mechanical/conventional breeding system with a molecular biology-based system using genetic transformation and molecular markers. This substitution eliminates the need for lengthy phenotypic evaluation cycles and enables precise control over trait inheritance, thereby reducing time loss and improving breeding reliability.
2Stability of the object's composition
If conventional breeding techniques are used, then the breeding methodology is simple and widely applicable, but it produces genetic variability and environmental sensitivity that reduce consistency
Solution Approach 1:
The patent replaces conventional phenotypic selection with molecular marker-assisted selection and genetic transformation techniques. This substitution provides precise control over genetic composition, eliminating random genetic variability and environmental sensitivity while maintaining a manageable breeding program through standardized molecular protocols.
Solution Approach 2:
The patent uses molecular copying of specific genetic markers and traits rather than relying on phenotypic copying through conventional breeding. This allows exact replication of desirable genetic characteristics without the variability inherent in phenotypic selection, achieving genetic stability while keeping the breeding program organized through marker-based tracking.
3Productivity
If conventional breeding is used to achieve high yield and desirable traits, then the approach is accessible to traditional breeders, but it is unpredictable and leads to inconsistent results
Solution Approach 1:
The patent replaces unpredictable phenotypic selection with molecular marker-assisted selection that provides predictable genetic outcomes. By selecting and transforming plants based on known molecular markers associated with high yield and desirable traits, the breeding process becomes predictable and reliable, ensuring consistent production of high-yielding varieties.
Solution Approach 2:
The patent implements feedback mechanisms through molecular marker analysis that continuously monitors and guides the breeding process. This feedback allows real-time adjustment of breeding strategies based on genetic data, ensuring predictable outcomes and reliable production of high-yield varieties with consistent characteristics.
