Hybrid Corn CH140757 Uniformity via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corn breeding techniques face challenges in developing uniform hybrid plants with desirable traits such as high yield, disease resistance, and uniformity, as they often result in non-uniform and unpredictable performance due to genetic differences between cross-pollinated plants.
Innovation Solution
The development of the hybrid corn variety CH140757, which incorporates cytoplasmic or nuclear factors for male sterility and desired traits like herbicide resistance, insect resistance, and disease resistance, using genetic loci introduced through backcrossing or genetic transformation, and tissue culture techniques to ensure consistent regeneration of plants with specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination is used to combine desirable traits from different plants, then genetic diversity and potential for new traits are improved, but uniformity and predictability of hybrid performance deteriorate
Solution Approach 1:
The patent segments the breeding process into distinct phases: creating homozygous inbred lines through repeated self-pollination, then crossing these inbreds to produce uniform F1 hybrids. This segmentation allows control over genetic composition at different stages, ensuring uniformity in the final hybrid while maintaining genetic diversity through the inbred parent development.
Solution Approach 2:
The patent applies preliminary action by first developing homozygous inbred plants through multiple generations of self-pollination and selection before creating the final hybrid cross. This preliminary preparation ensures that the parental lines are genetically stable and uniform, which then produces predictable and uniform F1 hybrids when crossed.
2Manufacturing precision
If self-pollination is used to develop homozygous inbred plants, then uniformity and genetic stability are improved, but the ability to combine diverse desirable traits deteriorates
Solution Approach 1:
The patent segments the breeding process into distinct phases: creating homozygous inbred lines through repeated self-pollination, then crossing these inbreds to produce uniform F1 hybrids. This segmentation allows control over genetic composition at different stages, ensuring uniformity in the final hybrid while maintaining genetic diversity through the inbred parent development.
Solution Approach 2:
The patent merges the benefits of self-pollination (uniformity) and cross-pollination (genetic diversity) by using homozygous inbred plants as parents for controlled crosses. The inbred lines provide uniformity and genetic stability, while the cross between different inbreds introduces and combines diverse desirable traits in the F1 generation.
3Ease of manufacture
If traditional breeding methods are used to develop new hybrids, then the process is straightforward, but development time and productivity are reduced
Solution Approach 1:
The patent applies preliminary action by first developing homozygous inbred plants through multiple generations of self-pollination and selection before creating the final hybrid cross. This preliminary preparation ensures that the parental lines are genetically stable and uniform, which then produces predictable and uniform F1 hybrids when crossed.
