Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maize breeding techniques face challenges in combining desirable traits such as disease resistance, drought tolerance, and yield enhancement while maintaining uniformity and stability in hybrid varieties.
Innovation Solution
The development of the hybrid maize variety X13D112, produced by crossing proprietary Pioneer Hi-Bred International inbred varieties, incorporates locus conversions and transformation processes to introduce specific traits, enhancing resistance to abiotic stresses, diseases, and improving agronomic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding techniques are used to combine desirable traits, then disease resistance and drought tolerance can be improved, but maintaining uniformity and stability of the hybrid variety becomes difficult
Solution Approach 1:
The patent applies parameter changes by utilizing locus conversion technology to precisely modify specific genetic loci while maintaining the overall genetic background. This allows introduction of desirable traits (disease resistance, drought tolerance) through targeted genetic modifications at specific loci, thereby improving reliability without compromising the uniformity and stability of the hybrid variety's overall composition.
2Productivity
If multiple desirable traits are combined in a single hybrid, then yield and agronomic quality improve, but the complexity of breeding and maintaining uniformity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex trait combination process into manageable loci-specific conversions. Instead of attempting to combine multiple traits through traditional multi-generational breeding, the invention segments the task into targeted locus conversions, where each desirable trait is introduced through specific locus modification. This reduces breeding process complexity while achieving multiple trait integration in a single hybrid variety.
Solution Approach 2:
The patent utilizes parameter changes through locus conversion technology to efficiently combine multiple desirable traits. By making targeted genetic modifications at specific loci rather than through traditional crossing and selection, the breeding process complexity is reduced while achieving integration of multiple traits that improve yield and agronomic quality.
3Reliability
If locus conversion and transformation processes are used to introduce specific traits, then resistance to abiotic stresses and diseases improves, but the manufacturing complexity of the variety increases
Solution Approach 1:
The patent applies parameter changes through locus conversion technology, which enables targeted genetic modifications at specific loci to introduce resistance to abiotic stresses and diseases. This method improves reliability by precisely introducing desired traits while maintaining the overall genetic integrity, and the standardized locus conversion process actually simplifies variety production compared to traditional breeding methods.
