Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean cultivars face challenges in combining desirable traits such as higher seed yield, disease resistance, drought tolerance, and improved fatty acid profiles, which are time-consuming to develop and require precise planning and resource management.
Innovation Solution
Development of a new soybean cultivar 25020904 with specific genetic modifications and breeding techniques to introduce traits like herbicide resistance, disease tolerance, and altered fatty acid composition, using methods such as mutagenesis and transformation, along with regenerable tissue cultures and genetic marker analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine desirable traits, then trait combination is achieved, but the development process takes 6-12 years and requires precise forward planning
Solution Approach 1:
The patent employs molecular marker-assisted selection to identify and select plants with desired traits before traditional breeding completion. By using DNA markers linked to target genes, breeders can preliminarily identify promising individuals in early generations, accelerating the breeding process while maintaining trait combination reliability.
2Adaptability or versatility
If multiple desirable traits are combined in a single cultivar, then agronomic quality improves, but the breeding process complexity increases
Solution Approach 1:
The patent segments the breeding process into distinct phases: initial parental selection based on molecular markers, intermediate crossing and selection, and final cultivar development. This segmentation allows systematic management of multiple trait combinations, reducing overall process complexity while achieving high agronomic quality.
Solution Approach 2:
Molecular markers serve as intermediaries between phenotypic observation and genotypic selection. These markers facilitate the identification and selection of plants carrying multiple desirable traits without requiring complex direct phenotypic evaluation of all trait combinations simultaneously.
3Productivity
If resource allocation is optimized for cultivar development, then breeding efficiency improves, but changes in direction must be minimized
Solution Approach 1:
The patent implements feedback mechanisms through molecular marker analysis at multiple breeding stages. This feedback allows real-time assessment of trait inheritance and selection progress, enabling efficient resource allocation and timely program adjustments without requiring complete program restructuring.
