Inbred Corn Line SLB11 Breeding Protocols
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 to enhance yield, trait technologies, and seed treatment options for better crop management.
Innovation Solution
The introduction of the inbred corn line SLB11, which is a new yellow dent inbred corn line with specific physiological and morphological characteristics, and methods for producing and breeding SLB11-derived corn plants, including self-pollination, sib-pollination, and hybrid production, along with techniques for enhancing seed resistance to stress conditions and disease using agricultural chemicals and genetic markers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional inbreeding techniques are used to develop new inbred corn lines, then genetic uniformity and purity are improved, but the process becomes slow and costly
Solution Approach 1:
The patent establishes a comprehensive set of preliminary selection criteria and standardized evaluation protocols before initiating the inbreeding process. By pre-defining the selection framework, morphological characteristics to monitor, and performance metrics, the breeding program can systematically evaluate progeny without ad hoc decision-making, thereby accelerating the development of new inbred lines while maintaining genetic uniformity
2Stability of the object's composition
If existing inbred parent corn lines are used repeatedly, then breeding program consistency is maintained, but commercial competitiveness is lost over time
Solution Approach 1:
The patent implements a dynamic inbred line evaluation system that continuously monitors performance metrics including yield, stress resistance, and morphological characteristics. This dynamic approach allows the breeding program to identify when existing lines are losing competitiveness and systematically introduce new genetic material through controlled crosses, thereby maintaining both consistency and commercial viability over time
3Stability of the object's composition
If extensive inbreeding is performed to achieve homozygosity, then genetic purity is improved, but line vigor decreases
Solution Approach 1:
The patent establishes continuous performance monitoring of inbred lines across multiple generations and environmental conditions. By maintaining ongoing evaluation of vigor metrics alongside purity assessment, the program can identify the optimal generation for line deployment before significant vigor loss occurs, and systematically refresh the breeding pool through strategic crosses when vigor thresholds are approached

AI summary
An inbred corn line, designated SLB11, the plants and seeds of the inbred corn line SLB11, methods for producing a corn plant, either inbred or hybrid, produced by crossing the inbred corn line SLB11 with itself or with another corn plant, and hybrid corn seeds and plants produced by crossing the inbred line SLB11 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 SLB11, to methods for producing other inbred corn lines derived from inbred corn line SLB11 and to the inbred corn lines derived by the use of those methods.
