Maize Inbred PH2G24 Breeding Acceleration via Preliminary Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties is a time-consuming process that takes six to twelve years, and there is a continuous need for stable, high-yielding maize varieties with improved traits such as disease resistance, drought tolerance, and better agronomic characteristics.
Innovation Solution
A novel maize variety, PH2G24, is developed through careful breeding and selection, incorporating traits like male sterility, disease resistance, and improved agronomic characteristics, using techniques such as backcross conversion and genetic transformation, and can be used to produce hybrid seeds through controlled pollination processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding processes are used to develop new varieties with desirable traits, then the varieties achieve stable high yielding characteristics, but the development process takes six to twelve years which is time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing inbred line PH2G24 with specific desirable traits (disease resistance, yield potential, agronomic characteristics) before hybrid development. This advance preparation of parental material with known superior traits accelerates the breeding process while ensuring reliable yield stability in the final hybrid varieties.
2Adaptability or versatility
If multiple desirable traits are combined in a single maize variety through breeding, then the variety achieves improved disease resistance, drought tolerance, and yield, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The patent merges multiple desirable traits (disease resistance, drought tolerance, high yield potential, improved agronomic characteristics) into a single inbred line PH2G24 through systematic breeding. This consolidation of traits in one parental line simplifies subsequent hybrid development while achieving comprehensive trait improvement in the final varieties.
Solution Approach 2:
The inbred line PH2G24 serves as a universal parental source that can be crossed with multiple different inbred lines to produce various hybrid varieties, all inheriting its desirable traits. This multi-functional inbred line acts as a foundational genetic resource for developing multiple hybrid varieties with consistent improvement across different trait combinations.
3Stability of the object's composition
If conventional breeding methods are used to introduce new traits into maize varieties, then the traits are stably inherited, but the process requires six to twelve years from first cross to finished seed delivery
Solution Approach 1:
The patent applies preliminary action by completing extensive trait validation and characterization of inbred line PH2G24 before hybrid seed production. This advance preparation ensures stable inheritance of desirable traits while significantly reducing the time from first cross to finished seed delivery by eliminating subsequent validation steps.
