Corn Variety CV955045 Inbred Line Genetic Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in corn breeding is to develop uniform corn hybrids with desirable traits such as high yield, disease resistance, and uniform maturity, while maintaining genetic stability and avoiding unpredictable performance due to genetic non-uniformity.
Innovation Solution
The development of the corn variety CV955045, which is a stable inbred line that can be used to produce uniform hybrid plants. This variety can be crossed with other inbred lines to create hybrids with specific desirable traits, and it includes genetic factors that can confer male sterility or herbicide tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If corn plants are crossed to combine desirable traits, then yield and resistance are improved, but genetic uniformity deteriorates
Solution Approach 1:
The patent applies preliminary action by developing homozygous inbred plants through multiple generations of self-pollination and selection before creating hybrids. This preliminary inbreeding process establishes genetic uniformity and stability in the parental lines, ensuring that when these inbreds are crossed, the resulting hybrids exhibit consistent and predictable performance for desired traits such as yield and disease resistance.
2Stability of the object's composition
If inbred plants are developed through self-pollination, then genetic stability is improved, but time to maturity deteriorates
Solution Approach 1:
The patent applies preliminary action by conducting multiple generations of self-pollination and selection before hybrid development. This preliminary inbreeding process, while time-consuming, establishes genetic stability and homozygosity in the parental inbred lines, which then enables the production of uniform and stable hybrid plants with predictable maturity times when these inbreds are crossed.
3Adaptability or versatility
If cross-pollination is used to create hybrids, then trait combination is improved, but uniformity of progeny deteriorates
Solution Approach 1:
The patent applies preliminary action by first developing homozygous inbred plants through self-pollination and selection. These inbred plants serve as stable genetic foundations that, when crossed, produce uniform F1 hybrid progeny. The preliminary inbreeding ensures that the parental lines are genetically stable, which in turn guarantees uniformity in the hybrid progeny while still allowing for the combination of desirable traits from different inbred sources.
