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 stable and agronomically sound manner.
Innovation Solution
A novel maize variety, PH2FNV, is developed through careful breeding and selection, incorporating traits like male sterility, disease resistance, and improved agronomic characteristics, using techniques such as backcross conversion, genetic manipulation, and transformation, allowing for the creation of hybrid seeds with enhanced traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine desirable traits in maize, then stable high-yielding varieties can be developed, but the process takes six to twelve years which is time-consuming
Solution Approach 1:
The patent employs preliminary action by creating and maintaining a pre-characterized inbred maize line (PH2FNV) with a comprehensive set of desirable traits including disease resistance, drought tolerance, and improved agronomic characteristics. This pre-developed genetic foundation allows breeders to start hybrid development immediately without the lengthy process of creating the base inbred line each time, effectively performing the foundational breeding work in advance.
Solution Approach 2:
The patent utilizes parameter changes by introducing specific genetic modifications to the PH2FNV inbred line, such as male sterility traits and other heritable characteristics. These parameter changes in the genetic makeup allow for accelerated breeding through controlled crosses and hybrid production, reducing the time required while maintaining stability through precise genetic control.
2Productivity
If multiple desirable traits are combined in a single maize variety, then yield and resistance are improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies merging by consolidating multiple desirable traits including disease resistance, drought tolerance, and improved agronomic characteristics into a single pre-characterized inbred maize line (PH2FNV). This consolidation allows breeders to access all these traits simultaneously through a single genetic foundation, reducing the complexity of managing multiple separate breeding programs while maintaining high productivity.
Solution Approach 2:
The PH2FNV inbred line serves as a universal genetic foundation that can be used across multiple breeding programs and applications. Its multi-functionality is demonstrated by its ability to contribute desirable traits to various hybrid combinations while maintaining stability and performance across different environments, thereby simplifying the overall breeding program structure.
3Loss of time
If genetic manipulation and transformation techniques are used to introduce traits, then trait integration time is reduced, but the complexity of the genetic modification process increases
Solution Approach 1:
The patent employs copying by utilizing pre-characterized genetic material from the PH2FNV inbred line that has already been optimized with desirable traits. Instead of performing complex genetic manipulation each time, breeders can copy and utilize this proven genetic foundation, introducing only the specific additional traits needed while maintaining the stable, high-performing base genome.
Solution Approach 2:
The PH2FNV inbred line acts as an intermediary that facilitates trait integration. By serving as a stable genetic platform with pre-introduced desirable characteristics, it mediates between the complexity of genetic manipulation and the need for rapid trait integration, allowing breeders to work with a simplified, pre-optimized genetic background while still achieving rapid introduction of new traits.
