Hybrid Corn CH011235 Male Sterility and Trait Integration
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 introduction of new genetic modifications and traits.
Innovation Solution
The development of the hybrid corn variety CH011235, which incorporates a cytoplasmic or nuclear factor for male sterility and genetic modifications conferring traits like herbicide resistance, disease resistance, and altered metabolism, using techniques like genome editing and transgenic integration, along with tissue culture methods for regenerating plants with specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional corn breeding techniques are used, then hybrid varieties can be developed with desirable traits, but self-pollination occurs which limits genetic modification and trait introduction
Solution Approach 1:
The patent removes the capability for self-pollination by introducing male-sterile traits through genetic modification. This extraction of the self-pollination function allows complete control over pollination, enabling reliable introduction of new genetic traits without contamination from self-fertilization.
Solution Approach 2:
The patent uses male-sterile plants as an intermediary mechanism to control pollination. These plants cannot self-pollinate but can be controlled to cross-pollinate with specific selected parents, serving as a mediator that ensures genetic purity and enables precise trait introduction.
2Reliability
If male sterility factors are introduced to prevent self-pollination, then cross-pollination control is improved, but genetic stability may be compromised
Solution Approach 1:
The patent applies male sterility locally to specific plants in the breeding program rather than universally. By selectively modifying only the female parent plants to be male-sterile while keeping male parent plants fertile, the system maintains genetic stability in the overall population while achieving precise cross-pollination control where needed.
3Object-affected harmful factors
If genetic modifications are introduced for herbicide resistance and disease resistance, then crop protection is enhanced, but complexity of breeding program increases
Solution Approach 1:
The patent combines multiple desirable traits including male sterility, herbicide resistance, and disease resistance into single integrated plant lines. By merging these traits through coordinated breeding programs, the system achieves enhanced crop protection and pollination control simultaneously, rather than developing separate programs for each trait.
