Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maize breeding techniques face challenges in combining desirable traits such as disease resistance, drought tolerance, and high yield while maintaining uniformity and stability in hybrid maize varieties.
Innovation Solution
Development of the hybrid maize variety X90B043, produced by crossing proprietary Pioneer Hi-Bred International inbred varieties, which incorporates locus conversions and transformation processes to introduce specific traits, enhancing resistance to abiotic stresses and improving agronomic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding is used to combine desirable traits, then disease resistance and drought tolerance can be improved, but uniformity and stability of the hybrid variety deteriorates
Solution Approach 1:
The patent segments the breeding process into distinct parental inbred lines with specific trait combinations, allowing systematic combination of disease resistance and drought tolerance while maintaining uniformity through controlled crosses. The hybrid variety X90B043 is produced by crossing specific inbreds (PH13BK and PH18TN) that have been developed through separate selection processes.
Solution Approach 2:
The patent applies parameter changes by modifying genetic composition through locus conversions and transformation processes. Specific genetic loci are converted or transformed to introduce desirable traits (disease resistance, drought tolerance) while maintaining the overall genetic stability and uniformity of the hybrid variety.
2Productivity
If multiple desirable traits are combined in a single hybrid, then yield and agronomic quality improve, but the complexity of breeding process increases
Solution Approach 1:
The patent applies preliminary action by pre-developing parental inbred lines with specific trait combinations before the final hybrid cross. The inbreds PH13BK and PH18TN are developed in advance through systematic breeding and selection, allowing the final hybrid X90B043 to inherit multiple desirable traits without requiring complex multi-parent crosses.
Solution Approach 2:
The patent applies local quality by assigning specific trait combinations to different parental lines. PH13BK and PH18TN are developed with complementary strengths, allowing the hybrid to combine multiple desirable traits while simplifying the breeding process through targeted cross between two specialized parents.
3Reliability
If locus conversion and transformation processes are used to introduce specific traits, then resistance to abiotic stresses improves, but manufacturing complexity increases
Solution Approach 1:
The patent uses intermediary processes of locus conversion and transformation to introduce specific stress resistance traits. These intermediary genetic modifications serve as mediators between the parental inbreds and the final hybrid, allowing precise introduction of abiotic stress resistance while maintaining overall process manageability through standardized genetic engineering protocols.
