Hybrid Corn CH100288 Breeding via Cytoplasmic Male Sterility
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 CH100288, which incorporates genetic modifications and cytoplasmic male sterility traits to prevent self-pollination, along with a process for crossing parent plants to produce hybrid seeds, utilizing genetic loci for traits like herbicide resistance and disease resistance, and tissue culture methods for regenerating plants with specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional self-pollination breeding methods are used, then genetic uniformity can be achieved, but self-pollination prevents efficient hybrid seed production
Solution Approach 1:
The patent extracts the self-pollination capability from the corn plant by introducing cytoplasmic male sterility genes that prevent pollen formation. This allows the female parent to be completely dependent on cross-pollination, eliminating self-pollination interference while maintaining genetic uniformity in hybrid production
Solution Approach 2:
The patent introduces nuclear restorer genes as intermediaries that can restore male fertility in the F1 hybrid generation. These restorer genes act as mediators between the cytoplasmic male sterility and normal fertility, allowing controlled hybrid seed production while maintaining the ability to produce uniform hybrids
2Reliability
If multiple desirable traits are combined in hybrid varieties, then yield and resistance improve, but maintaining genetic stability becomes more difficult
Solution Approach 1:
The patent segments desirable traits into distinct parental lines, with each parent contributing specific traits (e.g., disease resistance, yield characteristics). This segmentation allows independent selection and optimization of traits in parents while ensuring stable inheritance in hybrids through controlled cross-pollination
Solution Approach 2:
The patent changes the genetic parameters by introducing cytoplasmic male sterility and nuclear restorer gene systems. This parameter change ensures that hybrids maintain stable inheritance of multiple traits while preventing unwanted self-pollination that could disrupt genetic consistency
