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 maize varieties, particularly in achieving optimal agronomic performance and resistance to environmental stresses.
Innovation Solution
Development of the maize variety 10159360 through crossing proprietary Pioneer Hi-Bred International, Inc. inbred varieties, incorporating locus conversion and transformation to introduce specific traits, and using methods like backcrossing and transformation to enhance genetic integrity and introduce desirable characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding is used to combine desirable traits, then disease resistance and yield may be improved, but uniformity and stability of plant characteristics deteriorate
Solution Approach 1:
The patent segments the breeding process into distinct generations (P1, P2, F1, F2, F3, F4) with specific selection criteria for each stage. This structured segmentation allows systematic combination of disease resistance traits while maintaining uniformity through controlled crossing and selection protocols.
Solution Approach 2:
The patent applies preliminary action by pre-selecting parental lines with specific desirable traits (disease resistance, yield potential) before crossing. The P1 and P2 generations undergo extensive evaluation and selection to ensure they possess the required traits, which are then combined in subsequent generations while maintaining stability.
2Productivity
If multiple desirable traits are combined in a single hybrid, then agronomic performance improves, but the complexity of breeding processes increases
Solution Approach 1:
The patent merges multiple desirable traits (disease resistance, yield, uniformity) into a single hybrid variety through systematic crossing of selected parental lines. The F1 generation combines traits from both P1 and P2 parents, and subsequent generations maintain this combination through controlled breeding protocols.
Solution Approach 2:
The breeding method described in the patent is universal and can be applied to develop various maize hybrids with different trait combinations. The same systematic approach (P1×P2→F1→F2→F3→F4) can be used to combine different sets of desirable traits, making the methodology multi-functional and broadly applicable.
3Productivity
If uniformity of plant characteristics is maintained for mechanical harvesting, then harvest efficiency improves, but genetic diversity and adaptability may be reduced
Solution Approach 1:
The patent applies local quality by maintaining uniformity in specific plant characteristics critical for mechanical harvesting (plant height, maturity timing, ear position) while preserving genetic diversity in other traits through the selection of diverse parental lines. This allows harvest efficiency to be optimized without completely sacrificing adaptability.
