Maize Inbred 1PLUG57 Accelerating Hybrid Development
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process that takes several years, and there is a continuous need for stable, high-yielding maize varieties that are agronomically sound and can perform well under various conditions and environments.
Innovation Solution
A novel maize variety, designated 1PLUG57, and processes for making 1PLUG57 are provided. This variety can be used to produce seed, plants, and plant parts with specific traits introduced through backcross conversion, genetic manipulation, and transformation. Additionally, hybrid maize seed and plants can be produced by crossing 1PLUG57 with another maize variety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding processes are used to develop new varieties, then stable and agronomically sound varieties can be obtained, but the development time is excessively long (6-12 years)
Solution Approach 1:
The patent applies preliminary action by pre-establishing a diverse panel of inbred lines with characterized traits before breeding begins. This allows breeders to quickly select appropriate parents and accelerate the breeding process while maintaining variety stability through systematic pre-screening and characterization of genetic material.
2Adaptability or versatility
If conventional breeding methods are used, then maize varieties can be developed, but the process is too slow to meet continuous market needs for improved varieties
Solution Approach 1:
The patent segments the breeding program into distinct functional components: a core panel of inbred lines with specific traits, multiple environmental test locations, and systematic evaluation protocols. This segmentation allows parallel development of multiple variety candidates simultaneously, increasing breeding productivity while maintaining adaptability through distributed environmental testing.
Solution Approach 2:
The patent creates a universal inbred line panel that can serve multiple breeding objectives and be deployed across different environmental conditions. This multi-functional resource panel enables the same genetic material to be evaluated for various agronomic traits and adapted to different markets, increasing both versatility and breeding efficiency.
3Reliability
If extensive testing and selection are performed to ensure variety stability, then reliable maize varieties are produced, but the breeding process becomes excessively time-consuming
Solution Approach 1:
The patent performs preliminary characterization and stability assessment of inbred lines before they are fully deployed in breeding programs. By pre-evaluating genetic stability and key traits of candidate lines, the system reduces the time required for subsequent testing and selection while maintaining variety reliability through advance verification of critical properties.
