Corn Inbred Line Breeding for Yield and Stress Resilience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for stable, high-yielding corn hybrids with superior parental lines that exhibit desirable traits to maximize ear and kernel production, while also providing resistance to pests, diseases, and tolerance to environmental stresses.
Innovation Solution
The development of a novel inbred corn line, KW4FP1932, which can be used to produce hybrid seeds with traits such as male sterility, herbicide resistance, insect resistance, disease resistance, water stress tolerance, and modified nutritional content through genetic modification and breeding techniques, including TILLING screening and backcrossing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used to develop corn hybrids, then basic yield potential can be achieved, but superior parental lines with multiple desirable traits (pest resistance, disease resistance, environmental stress tolerance) cannot be obtained
Solution Approach 1:
The patent combines multiple desirable traits (male sterility, herbicide resistance, insect resistance, disease resistance, water stress tolerance, and modified nutritional content) into a single inbred corn line through systematic breeding and genetic modification, creating a unified parental line that exhibits all these traits simultaneously for use in hybrid production
Solution Approach 2:
The inbred corn line KW4FP1932 serves as an intermediary parental line that bridges conventional breeding and genetic modification approaches, incorporating traits like male sterility and herbicide resistance through genetic modification while maintaining agronomic traits through conventional breeding, thereby producing hybrids with superior overall performance
2Adaptability or versatility
If genetic modification techniques are applied to introduce desirable traits, then traits such as herbicide resistance and insect resistance can be achieved, but complexity of the breeding process increases
Solution Approach 1:
The patent applies genetic modification techniques in advance during the inbred line development stage to incorporate desirable traits (male sterility, herbicide resistance, insect resistance) into the parental line, so that these traits are already present before hybrid production begins, simplifying the overall breeding program
Solution Approach 2:
The patent modifies specific genetic parameters of the inbred corn line by introducing genes for male sterility, herbicide resistance, and insect resistance through genetic modification, thereby changing the biological parameters of the plant to exhibit these desirable traits while maintaining other agronomic characteristics
3Reliability
If multiple traits are introduced through genetic modification, then resilience to environmental stresses and enhanced agronomic traits can be achieved, but time required for breeding and development increases
Solution Approach 1:
The patent incorporates multiple stress resistance traits and desirable agronomic traits during the inbred line development phase through genetic modification and conventional breeding, so that the parental line is pre-equipped with these traits before hybrid production begins, reducing the time needed for subsequent breeding cycles
Solution Approach 2:
The patent combines multiple trait introduction methods (genetic modification for specific traits like herbicide resistance and insect resistance, and conventional breeding for agronomic traits) into a unified breeding program that develops all desired traits simultaneously in a single inbred line rather than sequentially
