Hybrid Corn CH011036 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 CH011036, which incorporates genetic modifications and cytoplasmic male sterility traits to prevent self-pollination, along with tissue culture methods for regenerating plants with specific physiological and morphological characteristics, enables the production of seeds with enhanced traits like herbicide resistance and improved agronomic qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If self-pollination is allowed in corn breeding, then genetic diversity is maintained, but hybrid seed production efficiency deteriorates due to inability to prevent self-pollination
Solution Approach 1:
The patent extracts and removes the male reproductive capability from the female parent plant by introducing cytoplasmic male sterility (CMS) genes. This eliminates the harmful self-pollination function while preserving the female plant's ability to produce hybrid seeds when crossed with fertile male parents.
Solution Approach 2:
The patent uses CMS genes as an intermediary mechanism to control pollination. These genes act as a biological mediator that automatically prevents self-pollination in the female parent while allowing controlled cross-pollination with selected male parents, thereby improving hybrid seed production efficiency.
2Adaptability or versatility
If multiple desirable traits are combined in hybrid corn, then agronomic quality improves, but genetic stability deteriorates due to complexity of breeding
Solution Approach 1:
The patent segments the breeding process into distinct parental lines, each contributing specific desirable traits. The female parent provides CMS and other agronomic qualities, while the male parent contributes complementary traits. This segmentation allows systematic combination of multiple desirable traits while maintaining genetic stability through controlled crosses.
Solution Approach 2:
The patent creates hybrid corn varieties that universally combine multiple desirable traits including CMS for pollination control, disease resistance, herbicide tolerance, and improved agronomic qualities. This multi-functional approach allows a single hybrid variety to exhibit multiple beneficial characteristics simultaneously while maintaining genetic stability.
3Productivity
If cytoplasmic male sterility is introduced to prevent self-pollination, then hybrid seed production efficiency improves, but device complexity deteriorates due to genetic modification requirements
Solution Approach 1:
The patent employs cytoplasmic male sterility genes that enable the female parent plant to automatically prevent self-pollination without requiring external intervention or complex mechanical systems. The genetic mechanism serves itself by inherently controlling the pollination process, improving hybrid seed production efficiency while avoiding the need for complex artificial emasculation or isolation systems.
