Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maize breeding techniques face challenges in combining desirable traits such as disease resistance, drought tolerance, and uniformity, particularly in achieving consistent performance across varying environmental conditions.
Innovation Solution
Development of the maize variety PH12FT, which is a novel hybrid designed to combine resistance to diseases and abiotic stresses, along with improved agronomic traits like maturity and yield, through specific breeding processes and genetic modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding is used to combine desirable traits, then disease resistance and yield can be improved, but uniformity of plant characteristics and consistency across environmental conditions deteriorate
Solution Approach 1:
The patent segments the breeding process into multiple controlled crosses between specific inbred lines (PH12FT as parent) to systematically combine desired traits. This structured segmentation allows for precise control over trait inheritance and uniformity while maintaining adaptability through selective breeding combinations.
Solution Approach 2:
The patent utilizes controlled changes in genetic parameters through backcrossing and selection processes. By systematically altering genetic composition through defined breeding steps (F1, F2, backcross generations), the invention achieves both uniformity in desired traits and adaptability to different environments.
2Reliability
If multiple desirable traits are combined in a single variety, then disease resistance and drought tolerance improve, but the complexity of the breeding process increases
Solution Approach 1:
The patent merges multiple desirable traits (disease resistance, drought tolerance, uniformity) into a single maize variety PH12FT through systematic breeding. Multiple inbred lines with different beneficial traits are crossed and combined, integrating diverse genetic advantages into one unified variety that expresses all desired characteristics simultaneously.
Solution Approach 2:
The patent employs preliminary action by first developing and characterizing specific inbred lines (including PH12FT) with known trait profiles before combining them. This preliminary development and testing of parent lines allows for predictable and controlled integration of multiple traits, reducing the complexity of the overall breeding process.
3Productivity
If uniformity of plant characteristics is achieved for mechanical harvesting, then harvest efficiency improves, but genetic diversity and adaptability to varying conditions decrease
Solution Approach 1:
The patent creates a universally adaptable maize variety PH12FT that performs consistently across multiple functions and environments. The variety is bred to maintain uniform plant characteristics (height, maturity, ear placement) necessary for mechanical harvesting while simultaneously possessing genetic diversity that enables adaptation to different geographical conditions and environmental stresses.
Solution Approach 2:
The patent employs composite genetics by combining multiple inbred lines with complementary traits to create PH12FT. This genetic composite structure provides both the uniformity needed for mechanical harvesting and the diverse genetic background required for environmental adaptability, much like composite materials combine different properties in a single substance.
