Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corn breeding techniques struggle to develop hybrids with uniformity and stability, incorporating desirable traits such as yield, disease resistance, and drought tolerance, while maintaining efficient hybrid production methods.
Innovation Solution
The development of the hybrid corn variety CH010501, which includes genetic modifications for traits like male sterility, herbicide resistance, and disease resistance, achieved through methods like backcrossing and genetic transformation, ensuring uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional breeding methods are used to develop corn hybrids, then genetic diversity is maintained, but uniformity and genetic stability of the hybrid population deteriorates
Solution Approach 1:
The breeding program segments the development process into distinct phases: creating homozygous inbred lines through multiple generations of self-pollination, then crossing these stabilized lines to produce uniform F1 hybrids. This segmentation allows genetic stability to be achieved within each inbred line while maintaining the ability to generate diverse hybrid combinations.
Solution Approach 2:
The patent applies parameter changes by controlling the inbreeding coefficient and generation number to achieve desired levels of homozygosity. By adjusting these parameters, breeders can control the balance between genetic stability (through inbreeding) and the potential for hybrid vigor (through subsequent crossing).
2Productivity
If multiple desirable traits are combined in a single hybrid variety, then agronomic quality and yield improve, but the complexity of the breeding program increases
Solution Approach 1:
The patent merges multiple desirable traits into single hybrid varieties by crossing inbred lines that each contribute specific traits. For example, hybrids are developed combining disease resistance, yield potential, and adaptability to different environments through systematic crossing programs that integrate multiple parental contributions.
Solution Approach 2:
The breeding program develops inbred lines and hybrids that serve multiple functions: they provide disease resistance, yield improvement, and adaptability to various agricultural conditions. A single hybrid variety is designed to simultaneously address multiple agronomic requirements through its genetic composition.
3Manufacturing precision
If inbred plants are developed through extensive self-pollination, then genetic uniformity improves, but the time required for hybrid production increases
Solution Approach 1:
The patent applies preliminary action by conducting extensive self-pollination and selection during the inbred line development phase to achieve genetic uniformity before the hybrid production phase. This preliminary stabilization of parental lines ensures that subsequent hybrid crosses produce uniform F1 progeny without requiring additional generations of inbreeding, thus reducing overall breeding time.
