1PNJW73 Maize Inbred for Backcross Trait Integration
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 a novel maize variety, 1PNJW73, with specific traits introduced through backcross conversion, genetic manipulation, and transformation, including cytoplasmic male sterility and heritable traits like herbicide tolerance and disease resistance, along with processes for crossing and producing hybrid seeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding methods are used to combine desirable traits, then the traits can be successfully combined, but the process takes six to twelve years which is too time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-establishing inbred lines with specific desirable traits (such as disease resistance, yield components, and stress tolerance) before the actual variety development process. These pre-characterized inbred lines serve as ready-to-use genetic building blocks that can be quickly combined through controlled crosses, eliminating the need for time-consuming trait discovery and initial breeding steps.
Solution Approach 2:
The patent segments the complex trait combination process into manageable components by developing separate inbred lines, each optimized for specific traits (e.g., one line for disease resistance, another for yield). This segmentation allows parallel development of multiple trait-specific lines that can then be systematically combined, reducing overall development time while maintaining trait stability.
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the variety becomes more agronomically sound, but the breeding process complexity increases
Solution Approach 1:
The patent creates universal inbred lines that serve multiple functions: they can be used as parental lines for hybrid development, as genetic resources for future breeding programs, and as standards for trait evaluation. Each inbred line is developed to be multi-functional, reducing the need for separate specialized lines and simplifying the overall breeding system.
Solution Approach 2:
The patent systematically varies key breeding parameters such as crossing combinations, selection criteria, and evaluation conditions to optimize the combination of multiple traits. By controlling and adjusting these parameters methodically, the complex process of combining multiple desirable traits becomes more manageable and predictable.
