Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheat varieties often lack a balanced combination of desirable traits such as high seed yield, disease resistance, drought tolerance, and improved agronomic characteristics, limiting their performance and adaptability in various growing conditions.
Innovation Solution
Development of the wheat cultivar G18C2097, which incorporates a single locus conversion through genetic transformation to introduce specific traits like herbicide resistance, disease resistance, and improved agronomic qualities, combined with traditional breeding techniques to enhance yield and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional breeding techniques are used to combine desirable traits, then genetic diversity is maintained, but the speed of trait integration and precision of trait introduction is limited
Solution Approach 1:
The patent uses molecular markers as intermediary tools to bridge traditional breeding and modern genetics. These markers serve as detectable indicators that mediate the selection process, allowing breeders to track and select for specific traits with high precision while maintaining the framework of traditional breeding programs. This resolves the contradiction by enabling precise trait identification without requiring complex genetic engineering.
Solution Approach 2:
The patent replaces phenotypic selection (mechanical/physical observation of traits) with genotypic selection using molecular markers. Instead of visually assessing and selecting plants based on observable characteristics, the invention uses DNA-based markers to directly identify and select for desired genetic traits, significantly improving both speed and precision of trait integration.
2Adaptability or versatility
If multiple traits are combined in a single variety, then overall performance and adaptability improve, but the complexity of breeding programs and time required increase
Solution Approach 1:
The patent segments the complex task of combining multiple traits into manageable units by using specific molecular markers for each desired trait. Each marker represents a discrete genetic target that can be independently tracked and selected. This segmentation allows breeders to systematically accumulate multiple traits through sequential selection rather than attempting to manage all traits simultaneously, reducing program complexity while maintaining adaptability.
3Ease of operation
If selection based on phenotypic traits is used, then simple selection criteria are available, but accuracy of trait selection and early identification of desirable plants is limited
Solution Approach 1:
The patent performs preliminary genetic identification at the seedling or early plant stage using molecular markers before phenotypic traits fully express. By detecting the presence of desired genetic markers early in development, the system enables selection decisions to be made before visual trait expression, significantly improving selection accuracy while maintaining operational simplicity through standardized marker-based assays.
