Hybrid Corn CH011083 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 CH011083, 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 hybrid seeds with enhanced traits like herbicide resistance and improved agronomic qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional self-pollination breeding methods are used, then genetic stability is maintained, but hybrid seed production efficiency is limited
Solution Approach 1:
The patent extracts the self-pollination capability from the corn plant by introducing cytoplasmic male sterility traits, which eliminate pollen production in the female parent. This extraction prevents self-pollination and enables controlled cross-pollination for hybrid seed production, resolving the contradiction between maintaining genetic stability and improving hybrid seed production efficiency
Solution Approach 2:
The patent uses cytoplasmic male sterility as an intermediary mechanism to control pollination. The sterile cytoplasm acts as a mediator that prevents self-pollination while allowing controlled cross-pollination with fertile male parents, thereby improving hybrid seed production efficiency without compromising genetic stability through uncontrolled selfing
2Productivity
If cytoplasmic male sterility is introduced to prevent self-pollination, then hybrid seed production efficiency improves, but device complexity increases
Solution Approach 1:
The patent employs self-service by utilizing the plant's own cytoplasmic inheritance system to control pollination. The female parent's sterile cytoplasm automatically prevents self-pollination without requiring external intervention or complex mechanical devices, improving hybrid seed production efficiency while adding minimal system complexity
Solution Approach 2:
The patent changes the genetic parameter of the female parent by introducing cytoplasmic male sterility traits, which alter the pollen production capability. This parameter change enables controlled cross-pollination and improves hybrid seed production efficiency without requiring complex breeding systems, as the genetic modification itself provides the control mechanism
