KW6FD0043 Inbred Corn Line for Stable, High-Yield Hybrids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for developing stable, high-yielding corn hybrids with superior parental lines that exhibit desirable traits for maximizing kernel production and providing food for both humans and animals.
Innovation Solution
The development of a novel inbred corn line, KW6FD0043, which can be used to produce seeds and plants with specific morphological and physiological characteristics, and can be modified through mutagenesis, transgenesis, and backcrossing to introduce traits such as male sterility, herbicide resistance, and disease resistance, among others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional breeding methods are used to develop corn hybrids, then stable parental lines can be obtained, but the yield and agronomic performance are limited
Solution Approach 1:
The patent applies parameter changes by modifying the genetic composition of corn parental lines through controlled crossing and selection. Specifically, the inbred line KW6FD0043 was developed through systematic breeding to achieve superior yield parameters (78-88 bushels/acre) while maintaining hybrid stability, representing a quantitative improvement in productivity parameters without sacrificing reliability
2Productivity
If new corn inbred lines are developed to maximize yield, then kernel production increases, but the complexity of breeding programs increases
Solution Approach 1:
The breeding program was segmented into distinct phases: developing inbred line KW6FD0043 with specific yield traits, testing it in hybrid combinations across multiple locations and environments, and selectively advancing superior combinations. This segmentation allowed systematic improvement of yield (78-88 bushels/acre) while managing program complexity through structured evaluation at Morris, Minnesota and other locations
3Productivity
If corn hybrids are optimized for high yield, then food supply capacity increases, but adaptability to different environmental conditions may be reduced
Solution Approach 1:
The patent implements dynamics by evaluating the inbred line KW6FD0043 in multiple hybrid combinations across different locations and environmental conditions. The selection process dynamically identifies hybrids that maintain high yield (78-88 bushels/acre) across varying environments, allowing the breeding program to adapt to different growing conditions while preserving productivity
