Maize Inbred PH41R5 Accelerating Hybrid Development
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process, taking six to twelve years, and existing technologies face challenges in creating stable, high-yielding maize varieties with desirable traits such as disease resistance, drought tolerance, and improved agronomic characteristics.
Innovation Solution
A novel maize variety, PH41R5, is developed through careful breeding and selection, incorporating traits like male sterility, disease resistance, and drought tolerance, achieved through backcross conversion, genetic manipulation, and transformation, allowing for the creation of hybrid seeds with enhanced agronomic properties.

Engineering Contradiction Analysis
1Reliability
If traditional breeding processes are used to develop new maize varieties, then stable and high-yielding varieties with desirable traits can be achieved, but the process takes six to twelve years which is time-consuming
Solution Approach 1:
The patent applies preliminary action by developing and maintaining a pre-characterized inbred maize line (PH41R5) with known genetic traits including male sterility, disease resistance, and drought tolerance. This pre-prepared genetic material can be immediately crossed with other varieties to produce hybrids, eliminating the need for lengthy breeding processes and reducing development time from 6-12 years to a single growing season.
Solution Approach 2:
The patent utilizes copying by creating genetically identical copies of the PH41R5 inbred line through controlled self-pollination and inbreeding. These copied genetic materials maintain the same desirable traits and can be distributed to multiple growers simultaneously, allowing parallel development of multiple hybrid varieties without repeating the entire breeding process.
2Adaptability or versatility
If multiple desirable traits are combined in a single maize variety, then disease resistance, drought tolerance, and yield can be improved, but the breeding process becomes more complex
Solution Approach 1:
The patent merges multiple desirable traits (male sterility, disease resistance, drought tolerance, and high yield potential) into a single integrated inbred maize line (PH41R5). This consolidated genetic package simplifies the breeding process by providing a ready-made parent line that contributes all these traits simultaneously to hybrid offspring, eliminating the need for separate breeding programs for each trait.
Solution Approach 2:
The PH41R5 inbred line serves multiple functions: it provides male sterility for hybrid seed production, confers disease resistance, provides drought tolerance, and contributes to high yield potential. This multi-functional genetic material can be used as a parent in various hybrid combinations across different environments and farming systems, reducing overall breeding complexity.
