Maize Variety X6H867 Trait Integration via Merging and Local Quality
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 in a single hybrid, while maintaining uniformity and agronomic quality, especially under stress conditions.
Innovation Solution
The development of the maize variety X6H867, produced by crossing proprietary Pioneer Hi-Bred International inbred varieties, which incorporates traits like drought resistance, disease resistance, and high yield, along with processes for introgressing new traits through backcross conversion and transformation, to create stable and adaptable maize plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding techniques are used to combine multiple desirable traits, then the complexity of the breeding process increases, but the ability to successfully combine disease resistance, drought tolerance, and high yield in a single hybrid decreases
Solution Approach 1:
The patent combines multiple desirable traits (disease resistance, drought tolerance, high yield) into a single maize hybrid variety X6H867 through systematic breeding programs that integrate multiple selection criteria and crossing strategies, thereby merging previously separate trait combinations into one unified variety
2Productivity
If mechanical harvesting is implemented, then harvesting efficiency increases, but the requirement for uniformity of plant characteristics becomes more critical
Solution Approach 1:
The patent applies local quality by selecting for uniformity in specific critical plant characteristics (germination, stand establishment, growth rate, maturity, plant and ear height) while allowing natural variation in other traits, thereby achieving the precision needed for mechanical harvesting without sacrificing overall genetic diversity
3Adaptability or versatility
If backcross conversion and transformation processes are used to introgress new traits, then the adaptability of maize varieties improves, but the time and resources required for trait introgression increase
Solution Approach 1:
The patent employs preliminary action by conducting extensive preliminary breeding work to develop inbred lines with desired traits before creating the final hybrid combination, and by using backcross conversion processes that pre-establish genetic backgrounds, thereby reducing the time needed for subsequent trait introgression and variety development
