Maize Inbred 1PMPL50 Breeding Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process, taking from six to twelve years from the first cross to the delivery of finished seed, and there is a continuous need for stable, high-yielding maize varieties that are agronomically sound and adaptable to various conditions and environments.
Innovation Solution
A novel maize variety, 1PMPL50, and processes for making it are provided, including crossing maize variety 1PMPL50 with another maize plant to produce hybrid maize seed, plants, or plant parts, and introducing traits through backcross conversion, genetic manipulation, and transformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional maize breeding processes are used to develop new varieties, then desirable traits can be combined in a single variety, but the development process takes six to twelve years which is time-consuming
Solution Approach 1:
The patent creates an inbred maize variety (1PMPL50) that has been pre-developed and characterized with specific desirable traits including yield components, plant morphology, and stress tolerance. This pre-prepared inbred line serves as a ready-to-use genetic platform that can be immediately crossed with other lines to produce hybrids, eliminating the need to start breeding from scratch and significantly reducing development time while maintaining trait combination capabilities
2Reliability
If maize breeders aim to develop stable, high-yielding varieties adaptable to different conditions, then agronomic quality is improved, but the process requires extensive testing and selection over multiple years
Solution Approach 1:
The patent specifies precise phenotypic parameters for inbred line 1PMPL50 including plant height (70-90 inches), ear position (50-65% from top), number of rows per ear (16-20), and kernel weight (0.3-0.5 ounces). These defined parameter ranges establish clear selection criteria that accelerate the breeding process by providing measurable targets for stability and performance, reducing the time needed for extensive testing while ensuring reliable agronomic quality

AI summary
A novel maize variety designated 1PMPL50 and seed, plants and plant parts thereof are provided. Methods for producing a maize plant comprise crossing maize variety 1PMPL50 with another maize plant are provided. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into 1PMPL50 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby are provided. Hybrid maize seed, plants or plant parts are produced by crossing the variety 1PMPL50 or a locus conversion of 1PMPL50 with another maize variety.
