Maize Inbred 1PPAV63 Accelerating Hybrid Development
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process, taking from six to twelve years from the first cross to the delivery of finished seed, and there is a continuous need for stable, high-yielding maize varieties that are agronomically sound and adaptable to various conditions and environments.
Innovation Solution
A novel maize variety, 1PPAV63, and processes for making it are provided, including crossing maize variety 1PPAV63 with another maize plant to produce hybrid maize seed, plants, or plant parts, and introducing traits through backcross conversion, genetic manipulation, and transformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding processes are used to develop new varieties, then stable and agronomically sound varieties can be achieved, but the development time is extremely long (6-12 years)
Solution Approach 1:
The patent applies preliminary action by developing and maintaining a pre-characterized inbred maize variety (1PPAV63) with a comprehensive set of desirable traits including disease resistance, yield potential, and adaptability. This pre-developed genetic foundation can be directly used in hybrid combinations, eliminating the need for lengthy breeding cycles to establish stable parental lines. The variety is ready for immediate deployment in hybrid seed production, significantly reducing the 6-12 year development timeline while maintaining reliability.
2Adaptability or versatility
If traditional breeding methods are used to combine desirable traits, then stable varieties can be developed, but the process requires extensive time for multiple crosses and selections
Solution Approach 1:
The patent merges multiple desirable traits into a single integrated inbred variety (1PPAV63), combining disease resistance, yield potential, and environmental adaptability that were previously developed separately through multiple breeding cycles. This consolidated genetic package can be directly applied in hybrid combinations, achieving trait combination without the time-consuming sequential crossing and selection processes that traditionally required 6-12 years.
3Productivity
If new maize varieties are developed through conventional breeding, then high-yielding and stable varieties can be produced, but the process is extremely time-consuming and slow
Solution Approach 1:
The patent applies preliminary action by pre-developing inbred variety 1PPAV63 with optimized yield potential and agronomic characteristics before it is needed for commercial deployment. This pre-characterized genetic material can be immediately used in hybrid seed production programs, eliminating the 6-12 year timeline that would otherwise be required to develop high-yielding varieties through conventional breeding cycles.
