Hybrid Corn CH524818 Uniformity via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corn breeding techniques face challenges in developing uniform hybrid varieties with desirable traits such as high yield, disease resistance, and uniform germination due to genetic non-uniformity in cross-pollinated plants, which affects performance predictability.
Innovation Solution
The development of the hybrid corn variety CH524818, which includes genetic loci for traits like male sterility, herbicide resistance, and disease resistance, combined with cytoplasmically-inherited traits and transgenes, to create a stable and uniform population with improved agronomic characteristics, using methods like backcrossing and genetic transformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination is used to develop corn hybrids, then genetic diversity and trait combination are improved, but genetic non-uniformity increases making performance unpredictable
Solution Approach 1:
The patent applies homogeneity by developing highly inbred parental lines that are genetically uniform and homozygous. By crossing two uniform inbred lines, the resulting F1 hybrid population achieves uniformity in gene expression and performance while maintaining the benefits of cross-pollination for trait combination.
Solution Approach 2:
The patent segments the breeding process into distinct stages: developing pure inbred parental lines through multiple generations of self-pollination, then crossing these standardized lines to produce uniform F1 hybrids. This segmentation allows genetic diversity to be captured in the parental lines while ensuring uniformity in the commercial hybrid population.
2Stability of the object's composition
If inbred plants are developed through self-pollination to achieve uniformity, then genetic uniformity is improved, but loss of heterosis and reduced vigor occur
Solution Approach 1:
The patent combines the uniformity of inbred lines with the vigor of hybrid plants by crossing two different inbred parental lines. The F1 hybrid offspring inherit uniform genetics from the standardized parents while expressing heterosis, achieving both genetic uniformity and high productivity.
3Reliability
If multiple breeding generations are performed to develop superior inbreds, then trait stability is improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by extensively developing and stabilizing parental inbred lines before the actual hybrid crossing. This upfront work in creating uniform, trait-stabilized parental lines ensures that the commercial hybrid program can proceed efficiently without requiring additional generations of testing and stabilization.
