Hybrid Corn CH011145 Cytoplasmic Male Sterility Seed Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corn breeding techniques face challenges in developing hybrid varieties that combine desirable traits such as high yield, disease resistance, and uniformity, while maintaining genetic stability and avoiding self-pollination, which limits the efficiency of hybrid seed production.
Innovation Solution
The development of the hybrid corn variety CH011145, which incorporates genetic modifications and cytoplasmic male sterility traits to prevent self-pollination, along with specific genetic loci conferring herbicide resistance, insect resistance, and other desirable characteristics, using advanced breeding methods and genetic transformation techniques like genome editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical emasculation is used to prevent self-pollination, then hybrid seed production is achieved, but labor intensity and production cost increase
Solution Approach 1:
The patent replaces the mechanical process of physical emasculation with a biological mechanism (cytoplasmic male sterility) that naturally prevents pollen production. This substitution eliminates the need for manual or mechanical removal of male reproductive organs, thereby reducing labor intensity while maintaining reliable prevention of self-pollination in hybrid seed production
2Productivity
If cytoplasmic male sterility is introduced to prevent self-pollination, then labor intensity is reduced, but genetic complexity increases
Solution Approach 1:
The patent employs cytoplasmic male sterility where the plant's own cytoplasmic genetics automatically prevent pollen production without requiring external intervention. The sterile cytoplasm inherently controls the male reproductive function, allowing the system to self-regulate and eliminate the need for physical emasculation while maintaining hybrid seed production efficiency
3Reliability
If multiple desirable traits are combined in a single hybrid variety, then agronomic performance is improved, but breeding complexity increases
Solution Approach 1:
The patent combines multiple desirable traits (disease resistance, yield improvement, stress tolerance) into a single hybrid variety by merging the genetic contributions of two specialized inbred lines. Each parent line contributes specific trait combinations, and their merger in the F1 hybrid produces a variety with comprehensive agronomic performance while streamlining the breeding program through targeted parental selection
