1PUMV66 Maize Inbred for Stable Multi-Trait Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties is a time-consuming process that requires years to combine desirable traits such as disease resistance, drought tolerance, and high yield, posing challenges in efficiently producing stable and agronomically sound maize varieties.
Innovation Solution
The development of the novel maize variety 1PUMV66, which incorporates genetic traits through backcross conversion, genetic manipulation, and transformation, including cytoplasmic male sterility, to enhance resistance, yield, and adaptability, along with processes for producing hybrid seeds and plants.

Engineering Contradiction Analysis
1Reliability
If traditional maize breeding methods are used to combine desirable traits, then the resulting variety has improved resistance, yield, and adaptability, but the development process takes six to twelve years
Solution Approach 1:
The patent applies preliminary action by pre-establishing inbred lines with specific desirable traits (disease resistance, drought tolerance, yield components) before combining them. The inbred lines are developed and characterized in advance, allowing for systematic combination in controlled crosses rather than random breeding trials, thus reducing the overall development time while maintaining trait stability.
Solution Approach 2:
The breeding process is segmented into distinct phases: developing individual inbred lines with specific traits, evaluating them separately, and then combining selected lines in controlled crosses. This segmentation allows parallel development of multiple trait components, reducing the sequential time required for traditional breeding while ensuring each trait is stabilized before combination.
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the variety achieves maximal yield over different conditions, but the breeding process becomes more complex
Solution Approach 1:
The patent creates inbred lines that serve multiple functions: some lines provide disease resistance, others provide drought tolerance, and others contribute yield components. These specialized inbred lines are then combined in hybrids to achieve multi-trait varieties with maximal yield across different environments. This multi-functionality approach allows systematic combination of traits without proportionally increasing breeding complexity.
Solution Approach 2:
Different inbred lines are developed with specific local qualities or specialized traits (e.g., one line specializes in disease resistance, another in drought tolerance). When combined in hybrid crosses, these locally optimized traits work together to create a variety with broad environmental adaptability, allowing the breeding program to manage complexity by focusing on specific trait optimizations in separate lines.
