Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corn breeding techniques struggle to develop hybrids with uniformity and stability, incorporating desirable traits such as yield, disease resistance, and drought tolerance, while maintaining efficient hybrid production methods.
Innovation Solution
The development of the hybrid corn variety CH010477, which includes genetic modifications for traits like male sterility, herbicide resistance, and disease resistance, achieved through methods like backcrossing and genetic transformation, ensuring uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional corn breeding techniques are used, then hybrid production can be maintained, but uniformity and stability of desirable traits (yield, disease resistance, drought tolerance) are difficult to achieve
Solution Approach 1:
The patent applies preliminary action by developing and establishing inbred lines with stable, desirable traits before creating the hybrid variety. The inbred lines are bred and selected in advance to ensure uniformity and stability of traits such as yield, disease resistance, and drought tolerance, which then serve as reliable parents for hybrid production.
Solution Approach 2:
The patent utilizes parameter changes by incorporating genetic modifications and selective breeding to alter and optimize specific traits in the corn variety. This includes changing genetic parameters to achieve desired characteristics like herbicide resistance, disease resistance, and drought tolerance while maintaining uniformity and stability across the hybrid population.
2Productivity
If multiple desirable traits are combined in a single hybrid, then agricultural productivity is enhanced, but the complexity of breeding and maintaining uniformity increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct stages: first developing and stabilizing individual inbred lines with specific desirable traits, then combining these segmented inbred lines to create the final hybrid. This segmentation allows each trait to be optimized and stabilized separately before integration, reducing overall breeding complexity.
Solution Approach 2:
The patent uses merging by combining multiple inbred lines with different desirable traits into a single hybrid variety. The inbred lines, each possessing stable and uniform traits, are merged through cross-breeding to produce a hybrid that integrates multiple desirable characteristics such as yield, disease resistance, and drought tolerance while maintaining uniformity.
