Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for stable, high-yielding corn hybrids that are agronomically sound to maximize ear or kernel production, addressing the challenge of developing superior parental lines for corn breeding.
Innovation Solution
A novel inbred corn line designated CV1 is introduced, along with methods for producing seeds, plants, and variants thereof, utilizing mutagenesis techniques and transgenic approaches to confer traits such as herbicide resistance, disease resistance, and improved nutritional quality, while maintaining the physiological and morphological characteristics of the CV1 line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional corn breeding methods are used to develop parental lines, then basic hybrid production is achieved, but yield potential and agronomic performance are limited
Solution Approach 1:
The patent applies parameter changes by introducing transgenes that modify specific genetic parameters of the corn plant. The inbred line CV1 contains transgenes conferring herbicide resistance (e.g., EPSPS gene for glyphosate resistance) and disease resistance (e.g., Bt genes for insect resistance), which are parameter modifications that enhance productivity while maintaining agronomic reliability through controlled genetic transformation rather than conventional breeding limitations.
2Productivity
If transgenic modification is used to enhance traits, then productivity and adaptability are improved, but genetic stability and uniformity may be compromised
Solution Approach 1:
The patent applies preliminary action by first developing a stable inbred line CV1 with desired transgenic traits through controlled transformation, then using this genetically stabilized line as a parent for hybrid production. The inbred line undergoes multiple generations of selfing and selection to ensure genetic uniformity and stability before being used for commercial hybrid seed production, thus ensuring both productivity enhancement and genetic stability.
Solution Approach 2:
The patent applies copying by reproducing the genetically modified inbred line CV1 through controlled self-pollination and tissue culture methods to maintain identical genetic composition. The inbred line serves as a stable genetic template that can be copied indefinitely while maintaining the transgenic traits, ensuring both productivity and genetic stability in subsequent hybrid productions.
3Adaptability or versatility
If multiple transgenic traits are introduced, then adaptability and resistance are enhanced, but device complexity and regulatory scrutiny increase
Solution Approach 1:
The patent applies universality by developing an inbred line CV1 that contains multiple transgenes conferring different functions: herbicide resistance (EPSPS gene), insect resistance (Bt genes), and disease resistance. This multi-functional inbred line can be used across different environmental conditions and agricultural practices, enhancing adaptability while the genetic modifications are integrated into a single unified genetic background that manages complexity.
