Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new inbred corn lines is a slow and costly process that requires expertise, and existing inbred parent corn lines lose commercial competitiveness over time, necessitating the creation of improved germplasm with enhanced yield, disease resistance, and trait technologies to maintain competitiveness.
Innovation Solution
The introduction of the inbred corn line SLB22, which is a new yellow dent inbred corn line with specific physiological and morphological characteristics, along with methods for producing and breeding SLB22-derived plants, including self-pollination, sib-pollination, and hybrid production, to enhance yield and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional inbreeding methods 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 applies preliminary action by pre-establishing a comprehensive set of molecular markers before the breeding process begins. These markers are used throughout subsequent generations to track and select for desired genetic traits, eliminating the need for time-consuming phenotypic evaluation in each generation and accelerating the inbreeding process while maintaining genetic uniformity
2Productivity
If existing inbred parent corn lines are used repeatedly, then breeding efficiency is maintained, but commercial competitiveness is lost over time
Solution Approach 1:
The patent applies parameter changes by utilizing molecular marker data to identify and select for novel genetic combinations that differ from traditional inbred lines. This allows the development of new inbred lines with updated genetic parameters that maintain breeding efficiency while restoring commercial competitiveness through improved adaptability and yield potential
3Reliability
If extensive breeding efforts are made to create improved germplasm, then yield and disease resistance are improved, but the process becomes more complex and costly
Solution Approach 1:
The patent applies feedback by using molecular marker information to continuously monitor and guide the breeding process. Real-time feedback from marker data allows breeders to make informed selections for disease resistance and yield traits, reducing the need for complex multi-generational field testing and simplifying the overall breeding process while maintaining high reliability of the desired traits

AI summary
An inbred corn line, designated SLB22, the plants and seeds of the inbred corn line SLB22, methods for producing a corn plant, either inbred or hybrid, produced by crossing the inbred corn line SLB22 with itself or with another corn plant, and hybrid corn seeds and plants produced by crossing the inbred line SLB22 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 SLB22, to methods for producing other inbred corn lines derived from inbred corn line SLB22 and to the inbred corn lines derived by the use of those methods.
