FF5130 Maize Inbred Line Trait Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corn breeding faces challenges in producing high-yielding, agronomically sound plants that are uniformly adapted across the U.S. Corn Belt, as regional growing conditions and specific issues like Gray Leaf Spot infection, cool temperatures, and soil pH levels require region-specific traits, and existing methods struggle to introduce desired traits efficiently into inbred lines.
Innovation Solution
The development of the maize inbred plant FF5130, which includes a mutant or transgenic gene conferring traits such as herbicide resistance, insect resistance, and disease resistance, along with a method for introducing desired heritable traits through crossing, backcrossing, and selection processes to produce hybrid seeds with specific agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop maize inbred lines, then uniformity and reproducibility are achieved, but the ability to introduce desired traits efficiently is limited
Solution Approach 1:
The patent applies preliminary action by pre-introducing desired traits into inbred lines through controlled crossing and backcrossing before hybrid production. The FF5130 inbred line was developed with specific traits (disease resistance, yield characteristics) already integrated through multiple generations of selective breeding, allowing these traits to be readily transferred to hybrids without complex modifications during hybridization.
Solution Approach 2:
The patent demonstrates universality by developing an inbred line (FF5130) that can serve multiple functions: it provides disease resistance, yield improvement, and adaptability to different regions. This single inbred line can be crossed with various other inbreds to produce different hybrids, each inheriting the desirable traits from FF5130 while maintaining regional adaptability.
2Stability of the object's composition
If inbred lines are used for hybrid production, then uniformity and reproducibility of hybrids are improved, but seed production vigor is reduced
Solution Approach 1:
The patent applies parameter changes by selecting and breeding the FF5130 inbred line with specific genetic parameters that enhance vigor while maintaining uniformity. The inbred line was developed through multiple generations of selection to optimize traits such as plant vigor, seed set, and adaptability, ensuring that hybrids produced from FF5130 exhibit both uniformity and high productivity.
Solution Approach 2:
The patent uses copying by producing multiple generations of the FF5130 inbred line through self-pollination and selective breeding, creating a stable, true-breeding line that consistently produces uniform hybrids. The inbred line serves as a reusable genetic template that can be crossed repeatedly with other inbreds to generate uniform hybrid seed lots.
3Productivity
If single-location selection is used for highly heritable traits, then selection efficiency is improved, but adaptability across regions is reduced
Solution Approach 1:
The patent applies segmentation by evaluating the FF5130 inbred line and its hybrid progeny across multiple locations and environments rather than relying on single-location selection. The breeding program divided the evaluation process into separate trials at different geographic locations, allowing selection of traits that perform consistently across diverse regional conditions, thus achieving both efficiency and adaptability.
Solution Approach 2:
The patent implements another dimension by expanding the selection criteria from single-location performance to multi-location and multi-environment performance. The FF5130 inbred line was evaluated not only for yield but also for adaptability across different regions, soil types, and climatic conditions, adding spatial and environmental dimensions to the selection process.
