KL20745C1 Inbred Corn Line for Stable, High-Yielding 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 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, KL20745C1, which can be used to create hybrid seeds through self-pollination or cross-pollination, and can be genetically modified to incorporate traits such as male sterility, herbicide resistance, insect resistance, disease resistance, and tolerance to water stress, among others, using methods like mutagenesis, TILLING, and genome editing techniques.
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 enhanced resistance and tolerance traits cannot be obtained
Solution Approach 1:
The patent applies parameter changes by modifying the genetic composition of corn parental lines through genome editing techniques. Specific genetic parameters are altered to introduce enhanced resistance and tolerance traits while maintaining yield potential, thereby resolving the contradiction between obtaining superior resistance traits and achieving high yield.
2Adaptability or versatility
If traditional inbred lines are used as parental lines, then hybrid production can proceed, but the hybrids lack enhanced agronomic traits and adaptability
Solution Approach 1:
The patent applies preliminary action by pre-modifying parental inbred lines with desired agronomic traits through genome editing before hybridization. This advance preparation ensures that the resulting hybrids inherit enhanced adaptability without requiring complex post-hybridization selection programs, thereby reducing breeding program complexity while improving adaptability.
3Reliability
If extensive genetic modification is applied to incorporate multiple traits, then enhanced resistance and tolerance are achieved, but the stability and uniformity of the inbred line may be compromised
Solution Approach 1:
The patent applies local quality by implementing targeted genome editing at specific loci rather than widespread genetic modification. This approach introduces desired resistance and tolerance traits at precise locations in the genome while maintaining the overall stability and uniformity of the inbred line, thereby resolving the contradiction between enhancing traits and preserving line stability.
