Hybrid Corn CH011211 Cytoplasmic Male Sterility Trait
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 trait introduction and hybrid seed production.
Innovation Solution
The development of the hybrid corn variety CH011211, which incorporates genetic modifications and cytoplasmic male sterility traits, allows for controlled cross-pollination and introduces heritable traits like herbicide resistance and disease resistance through genetic locus modifications, using techniques like genome editing and transgenic integration, ensuring stable and uniform hybrid production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional self-pollination breeding techniques are used, then genetic stability is maintained, but trait introduction efficiency and hybrid seed production are limited
Solution Approach 1:
The patent uses male sterility cytoplasm as an intermediary mechanism to prevent self-pollination and enable controlled cross-pollination. The cytoplasmic male sterility trait acts as a mediator that blocks self-fertilization while allowing controlled hybridization, thereby improving trait introduction efficiency without compromising genetic stability through uncontrolled breeding
Solution Approach 2:
The patent modifies the pollination parameter by introducing cytoplasmic male sterility to change the fertilization mode from self-pollination to controlled cross-pollination. This parameter change enables efficient hybrid seed production while maintaining genetic stability through controlled parental selection
2Productivity
If self-pollination is prevented to enable cross-pollination, then hybrid production is improved, but control over pollination process becomes more difficult
Solution Approach 1:
The patent employs self-service mechanism where the male sterile plants automatically prevent self-pollination through their inherent cytoplasmic sterility trait. This eliminates the need for manual emasculation or complex pollination control measures, making hybrid seed production easier while maintaining high productivity
Solution Approach 2:
The cytoplasmic male sterility trait serves as an intermediary that automatically controls the pollination process by blocking self-fertilization pathways. This natural biological mediator simplifies operation by eliminating manual intervention requirements while enabling efficient hybrid seed production
