Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new inbred corn lines is a slow and costly process, requiring expertise and numerous steps, and existing inbred parent corn lines lose commercial competitiveness over time, necessitating the need for improved germplasm with enhanced yield, disease resistance, and trait technologies.
Innovation Solution
The introduction of the inbred corn line WUC57, which is a yellow dent inbred corn line with specific physiological and morphological characteristics, and methods for producing and utilizing it, including self-pollination, sib-pollination, and hybrid production, along with techniques for enhancing seed resistance to stress conditions and incorporating desirable traits through breeding and genetic modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional inbreeding techniques are used to develop new inbred corn lines, then new inbred lines can be obtained, but the process is slow and costly
Solution Approach 1:
The patent applies preliminary action by developing and maintaining a pre-characterized inbred corn line (WUC57) with known genetic traits and performance characteristics. This allows breeders to start with a ready-to-use, well-defined parental line rather than developing new inbreds from scratch, significantly reducing the time and cost of breeding programs while maintaining systematic improvement through controlled self-pollination and selection
2Stability of the object's composition
If existing inbred parent corn lines are used repeatedly, then breeding continuity is maintained, but they lose commercial competitiveness over time
Solution Approach 1:
The patent applies dynamics by creating a living, evolving inbred line (WUC57) that can be continuously regenerated and improved through controlled self-pollination and selection. Rather than using static, depleted parental lines, the system allows the inbred line to be dynamically renewed each generation, maintaining genetic stability through homozygosity while enabling continuous selection for improved yield, disease resistance, and other commercially competitive traits
3Manufacturing precision
If multiple breeding steps and expertise are required, then thorough selection is achieved, but the process complexity increases
Solution Approach 1:
The patent applies self-service by developing an inbred corn line (WUC57) that is highly homozygous and genetically stable, allowing it to breed true to type with minimal intervention. The line's inherent genetic uniformity enables reliable performance without requiring complex multi-generational testing and selection protocols, reducing breeding process complexity while maintaining thorough selection through the line's consistent, predictable inheritance patterns

AI summary
An inbred corn line, designated WUC57, the plants and seeds of the inbred corn line WUC57, methods for producing a corn plant, either inbred or hybrid, produced by crossing the inbred corn line WUC57 with itself or with another corn plant, and hybrid corn seeds and plants produced by crossing the inbred line WUC57 with another corn line or plant and to methods for producing a corn plant containing in its genetic material one or more transgenes and to the transgenic corn plants produced by that method. This invention also relates to inbred corn lines derived from inbred corn line WUC57, to methods for producing other inbred corn lines derived from inbred corn line WUC57 and to the inbred corn lines derived by the use of those methods.
