Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corn breeding methods are slow and costly, and existing inbred corn lines lose commercial competitiveness over time, necessitating the development of improved germplasm with enhanced yield and disease resistance.
Innovation Solution
The introduction of the inbred corn line SLB01, which offers improved grain yield and resistance to insects, weeds, and diseases, along with methods for producing hybrid seeds and plants using SLB01 as a parent, including techniques for controlling male sterility and incorporating transgenes for enhanced traits.
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, and vigor decreases
Solution Approach 1:
The patent applies preliminary action by developing inbred line SLB01 with pre-established desirable traits including disease resistance and yield potential through multiple generations of inbreeding and selection. This pre-developed inbred line can be directly used in hybrid production without requiring additional time-consuming breeding steps, thus resolving the contradiction between genetic stability and breeding productivity.
2Duration of action of stationary object
If existing inbred corn lines are used repeatedly, then breeding program continuity is maintained, but commercial competitiveness is lost over time
Solution Approach 1:
The patent applies parameter changes by introducing inbred line SLB01 with improved genetic parameters including enhanced disease resistance, yield potential, and adaptability. These parameter improvements restore commercial competitiveness while maintaining breeding program continuity through systematic replacement of older inbred lines with this newly developed line.
3Productivity
If inbred lines with higher yield potential are developed, then grain yield is improved, but resistance to pests and diseases may be compromised
Solution Approach 1:
The patent applies composite materials by creating inbred line SLB01 that combines multiple desirable genetic traits including disease resistance genes, yield potential genes, and adaptability genes into a single integrated inbred line. This composite genetic structure allows the line to simultaneously exhibit high grain yield and strong pest/disease resistance, resolving the contradiction between these two parameters.
4Reliability
If protective chemicals are applied to control pests and diseases, then plant health is improved, but production costs and environmental impact increase
Solution Approach 1:
The patent applies self-service by developing inbred line SLB01 with inherent genetic resistance to pests and diseases. This enables the corn plants to protect themselves against harmful organisms without requiring external protective chemicals, thereby maintaining plant health while reducing production complexity and environmental impact.

AI summary
An inbred corn line, designated SLB01, the plants and seeds of the inbred corn line SLB01, methods for producing a corn plant, either inbred or hybrid, produced by crossing the inbred corn line SLB01 with itself or with another corn plant, and hybrid corn seeds and plants produced by crossing the inbred line SLB01 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 SLB01, to methods for producing other inbred corn lines derived from inbred corn line SLB01 and to the inbred corn lines derived by the use of those methods.
