Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corn breeding techniques face challenges in developing new inbred corn lines that maintain commercial competitiveness over time, with existing lines losing vigor and requiring costly and expertise-intensive processes to produce hybrid corn varieties with improved yield and quality.
Innovation Solution
The development of the inbred corn line D050212, which offers increased grain yield and grain moisture, along with methods for producing and treating seeds to enhance resistance to stress conditions, thereby improving hybrid performance and flexibility in crop management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional inbreeding techniques are used to develop new inbred corn lines, then hybrid corn varieties can be produced, but the lines lose vigor over time and require costly and expertise-intensive processes to maintain commercial competitiveness
Solution Approach 1:
The patent applies preliminary action by developing and preserving elite inbred corn line D050212 with predetermined superior traits (yield, stress resistance, uniformity) before hybrid production. This pre-developed inbred line serves as a reliable foundation that maintains commercial competitiveness across multiple generations without requiring continuous expensive breeding efforts, thus resolving the contradiction between productivity and reliability over time
2Productivity
If extensive breeding efforts are made to develop new inbred lines, then improved hybrid performance can be achieved, but the process becomes costly and expertise-intensive
Solution Approach 1:
The patent applies copying by creating and replicating the proven elite inbred corn line D050212 with consistent superior traits across multiple generations and locations. Instead of continuously developing new lines through complex breeding processes, the same high-performing inbred line is copied and used repeatedly as a parent in hybrid production, maintaining hybrid performance while reducing breeding process complexity and costs
3Productivity
If inbred corn lines are developed for hybrid production, then grain yield can be improved, but the lines require frequent updates to maintain competitiveness
Solution Approach 1:
The patent applies parameter changes by developing inbred corn line D050212 with enhanced genetic parameters including improved stress resistance genes, yield-related quantitative trait loci, and uniformity characteristics. These parameter improvements allow the inbred line to maintain commercial competitiveness for extended periods without requiring frequent updates, as the enhanced genetic parameters provide sustained superior performance across varying environmental conditions and generations
