Maize Variety PH41MH Breeding via Molecular Markers
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 combining desirable traits such as disease resistance, drought tolerance, and high yield in a single variety that is agronomically sound across different conditions and environments.
Innovation Solution
A novel maize variety, PH41MH, 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 stable, high-yielding hybrids with improved agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop new maize varieties, then desirable traits such as disease resistance and drought tolerance can be combined, but the development process takes six to twelve years
Solution Approach 1:
The patent replaces traditional mechanical breeding methods (manual crossing and selection) with molecular marker technology and DNA-based selection systems. This substitution enables rapid identification and combination of desirable traits without requiring multiple generations of field testing, thereby reducing development time from 6-12 years to a fraction of that period while maintaining reliable disease resistance and drought tolerance traits
2Adaptability or versatility
If multiple desirable traits are combined in a single variety through traditional breeding, then agronomic soundness may be improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent introduces molecular markers as intermediary tools that mediate between multiple desirable traits and the final variety development process. These markers serve as detectable indicators that allow breeders to track and combine multiple traits (disease resistance, drought tolerance, yield) simultaneously through DNA analysis rather than complex multi-generational field trials, thereby reducing program complexity while maintaining agronomic soundness
