Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inbred corn lines lose commercial competitiveness over time, and there is a need for improved germplasm to enhance yield, disease resistance, and adaptability in corn breeding.
Innovation Solution
Development of the inbred corn line OOA25LY, which includes specific genetic traits that increase grain yield, silage tonnage, and resistance to insects, weeds, and diseases, along with methods for producing and utilizing OOA25LY-derived plants through crossing, tissue culture, and genetic modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional inbreeding techniques are used to develop new inbred corn lines, then existing inbred corn lines can be improved, but they lose commercial competitiveness over time
Solution Approach 1:
The patent applies parameter changes by introducing a specific inbred corn line OOA25LY with modified genetic parameters that restore commercial competitiveness. This line exhibits improved grain yield, silage tonnage, and disease resistance compared to traditional inbred lines, effectively reversing the decline in competitiveness over time through targeted genetic parameter optimization
2Stability of the object's composition
If inbred corn lines are developed through multiple generations of inbreeding, then homozygous plants are obtained, but the vigor of the lines decreases
Solution Approach 1:
The patent resolves this contradiction by introducing OOA25LY with optimized genetic parameters that maintain high homozygosity while restoring vigor. The line demonstrates improved productivity metrics including grain yield and silage tonnage despite being highly inbred, achieving a parameter configuration where stability and productivity coexist
3Quantity of substance
If additional inbreeding is performed after sufficient inbreeding is achieved, then more inbred seed is produced, but it merely increases seed without improving the line
Solution Approach 1:
The patent addresses this contradiction by introducing OOA25LY with superior genetic parameters that simultaneously increase seed quantity and improve productivity. The line exhibits enhanced grain yield and silage tonnage while producing abundant seed, breaking the diminishing returns pattern of traditional inbreeding where seed quantity increases without productivity improvement
4Stability of the object's composition
If inbred corn lines are used to produce hybrid corn lines, then hybrid vigor is achieved, but the parent inbred lines must maintain high uniformity which limits adaptability
Solution Approach 1:
The patent resolves this contradiction by introducing OOA25LY with optimized genetic parameters that maintain high uniformity for mechanical harvest compatibility while simultaneously improving adaptability to various production areas. The line demonstrates consistent performance across different environments while maintaining the uniformity required for hybrid production

AI summary
An inbred corn line, designated OOA25LY, the plants and seeds of the inbred corn line OOA25LY, methods for producing a corn plant, either inbred or hybrid, produced by crossing the inbred corn line OOA25LY with itself or with another corn plant, and hybrid corn seeds and plants produced by crossing the inbred line OOA25LY 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 OOA25LY, to methods for producing other inbred corn lines derived from inbred corn line OOA25LY and to the inbred corn lines derived by the use of those methods.
