SLA21 Inbred Corn Line Yield and Resistance Traits
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 resistance to pests, diseases, and environmental stresses.
Innovation Solution
The introduction of the SLA21 inbred corn line, which offers increased grain yield and improved resistance to insects, weeds, and diseases, along with seed treatment options for enhanced crop flexibility and cost-effective control, is used to produce hybrid corn plants with restored vigor and uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional corn breeding methods are used, then corn plants can be developed with desirable traits, but the breeding process is slow and costly
Solution Approach 1:
The patent applies preliminary action by developing and maintaining a ready-to-use inbred corn line (SLA21) with pre-established desirable traits including herbicide resistance, insect resistance, and high yield potential. This pre-developed germplasm can be immediately crossed with other lines to produce hybrids, eliminating the need for time-consuming breeding processes and allowing farmers to access improved varieties quickly.
2Productivity
If existing inbred corn lines are used, then corn production can be maintained, but commercial competitiveness is lost over time
Solution Approach 1:
The patent applies parameter changes by introducing SLA21 inbred line with improved genetic parameters including enhanced herbicide resistance, improved insect resistance, and increased yield potential. These parameter improvements restore and enhance commercial competitiveness compared to older inbred lines, allowing continuous productivity improvement through updated germplasm.
3Object-affected harmful factors
If protective chemicals are applied to control pests and diseases, then crop protection is achieved, but cost increases and environmental concerns arise
Solution Approach 1:
The patent applies self-service by incorporating genetic resistance traits directly into the SLA21 inbred line, enabling the corn plants to protect themselves against pests and diseases through their own genetic makeup. The inbred line possesses inherent resistance to multiple pests and diseases, reducing or eliminating the need for external protective chemical applications while maintaining effective crop protection.

AI summary
An inbred corn line, designated SLA21, the plants and seeds of the inbred corn line SLA21, methods for producing a corn plant, either inbred or hybrid, produced by crossing the inbred corn line SLA21 with itself or with another corn plant, and hybrid corn seeds and plants produced by crossing the inbred line SLA21 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 SLA21, to methods for producing other inbred corn lines derived from inbred corn line SLA21 and to the inbred corn lines derived by the use of those methods.
