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 CH341684, which incorporates genetic modifications and cytoplasmic male sterility traits to prevent self-pollination, along with specific genetic loci conferring herbicide resistance, disease resistance, and other desirable characteristics, using advanced breeding methods and genetic transformation techniques like genome editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional self-pollination breeding methods are used, then genetic uniformity can be achieved, but hybrid seed production efficiency is limited due to self-pollination
Solution Approach 1:
The patent extracts and removes the self-pollination capability from the corn plant by introducing cytoplasmic male sterility traits. This prevents the female parent from self-pollinating, forcing cross-pollination with male parents and enabling efficient hybrid seed production while maintaining genetic uniformity through controlled crossing.
Solution Approach 2:
The patent uses cytoplasmic male sterility as an intermediary mechanism to control pollination. The sterile cytoplasm acts as a mediator that blocks self-pollination pathways while allowing controlled cross-pollination, thus resolving the contradiction between productivity and genetic stability.
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 the genetic material into distinct parental lines, each contributing specific desirable traits. By dividing the complex trait combination into separate parental genomes and using controlled cross-pollination, the patent maintains genetic stability while combining multiple beneficial characteristics in the hybrid offspring.
Solution Approach 2:
The patent changes the genetic parameters of parental lines through selective breeding and genetic modification to optimize trait combinations. By adjusting genetic parameters in parent lines and controlling their cross-pollination, the patent achieves reliable disease resistance and yield while maintaining overall genetic stability in the hybrid system.
3Productivity
If cytoplasmic male sterility is introduced to prevent self-pollination, then hybrid seed production efficiency improves, but device complexity increases due to genetic modification requirements
Solution Approach 1:
The patent employs self-service mechanisms where the cytoplasmic male sterility trait automatically prevents self-pollination without requiring external intervention. The sterile cytoplasm serves itself to block unwanted pollination pathways, simplifying the breeding process despite the initial genetic modification complexity by eliminating the need for manual emasculation or other complex control measures.
