Maize Inbred PH48FK Reduces Breeding Cycle Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process, typically taking six to twelve years from the initial cross to the delivery of finished seed to farmers, due to the complexity of combining desirable traits such as disease resistance, drought tolerance, and high yield.
Innovation Solution
The introduction of the novel maize variety PH48FK, which can be crossed with other maize plants to produce seeds and plants with specific traits through backcross conversion, genetic manipulation, and transformation, allowing for the rapid development of stable, high-yielding maize varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding processes are used to combine desirable traits, then stable high-yielding varieties can be developed, but the process takes six to twelve years which is too time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-establishing an inbred maize line (PH48FK) with a comprehensive foundation of desirable traits including disease resistance, drought tolerance, and high yield potential. This pre-developed genetic platform allows breeders to start with a variety that already possesses multiple desired characteristics, eliminating the need to develop these traits from scratch in traditional breeding programs and significantly reducing the overall breeding cycle time while maintaining variety stability
2Adaptability or versatility
If multiple desirable traits are combined in a single maize variety, then agronomic performance and yield are improved, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The patent merges multiple desirable traits including disease resistance, drought tolerance, and high yield potential into a single integrated inbred maize line (PH48FK). By combining these traits in one pre-developed genetic platform, the patent simplifies the breeding process for end users who can then focus on developing specific hybrid varieties without having to separately breed for each trait, thereby reducing breeding process complexity while maintaining comprehensive agronomic performance
