Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maize breeding techniques face challenges in combining desirable traits such as disease resistance, drought tolerance, and uniformity, which are essential for high yield and agronomic quality, particularly in hybrid varieties.
Innovation Solution
Development of the hybrid maize variety X05F864, produced by crossing proprietary Pioneer Hi-Bred International, Inc. inbred varieties, incorporating locus conversion and transformation to introduce specific traits, enhancing resistance to abiotic stresses, diseases, and improving yield and maturity.
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 the time required for breeding and the complexity of the process increase
Solution Approach 1:
The patent employs preliminary action by pre-selecting and characterizing inbred parental lines (PH1D84 and PH1W4R) with specific desirable traits before hybridization. The inbred parents were developed through multiple generations of selection and evaluation for disease resistance, drought tolerance, and other agronomic qualities, so that when crossed to produce hybrid X05F864, the desired traits are already established in the parental genomes, reducing the time needed for subsequent breeding cycles.
2Productivity
If multiple desirable traits are combined in a single hybrid, then agronomic quality and yield are improved, but the uniformity of plant characteristics may deteriorate
Solution Approach 1:
The patent applies local quality by combining specific desirable traits from each parental inbred line into the hybrid X05F864. The inbred parent PH1D84 contributes traits such as disease resistance and structural characteristics, while PH1W4R contributes drought tolerance and other agronomic qualities. This targeted combination of local traits from each parent allows the hybrid to achieve high yield and multiple desirable characteristics while maintaining uniformity through the controlled cross between two homozygous inbred lines.
3Reliability
If hybrid maize varieties are developed with enhanced stress resistance, then reliability under environmental stress is improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent applies segmentation by dividing the complex task of developing stress-resistant hybrids into manageable components: first developing and characterizing individual inbred parental lines with specific stress resistance traits, then crossing these pre-characterized inbreds to produce the hybrid. This segmentation allows each parent to be optimized for specific traits independently, and the hybrid to inherit a combination of these traits, reducing the overall complexity compared to attempting to develop all traits simultaneously in a single breeding program.
