Hybrid Corn CH096048 Breeding for Genetic Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corn breeding techniques face challenges in developing uniform hybrid plants with desirable traits such as high yield, disease resistance, and uniformity, as existing methods often result in unpredictable performance due to genetic non-uniformity among hybrid plants.
Innovation Solution
The development of the hybrid corn variety CH096048, which incorporates cytoplasmic or nuclear factors for male sterility and desired traits like herbicide resistance, insect resistance, and disease resistance, using genetic transformation techniques and backcrossing methods to introduce specific genetic loci and cytoplasmically-inherited traits, ensuring consistent performance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used to develop hybrid corn, then corn varieties can be produced, but genetic non-uniformity among hybrid plants results in unpredictable performance
Solution Approach 1:
The patent applies preliminary action by developing and utilizing homozygous inbred parent lines before creating the hybrid. The inbred lines are produced through multiple generations of self-pollination and selection to achieve genetic uniformity and stability. This preliminary development of stable parental lines ensures that the resulting hybrid has predictable and uniform performance, resolving the issue of genetic non-uniformity in conventional breeding approaches.
2Stability of the object's composition
If self-pollination is used to develop homozygous inbred plants, then genetic uniformity is achieved, but the process requires multiple generations and careful selection
Solution Approach 1:
The patent employs copying by utilizing cytoplasmic male sterility (CMS) systems that can be propagated through backcrossing to maintain the desired genetic uniformity without requiring repeated self-pollination generations. The CMS inbred lines are copied and maintained through controlled crosspollination with maintainer lines, reducing the time needed to achieve and maintain genetic uniformity while still producing homozygous inbred plants with stable characteristics.
3Adaptability or versatility
If cross-pollination is used to create hybrid plants, then desirable traits from different parents can be combined, but genetic non-uniformity makes performance unpredictable
Solution Approach 1:
The patent applies local quality by developing cytoplasmic male sterility systems with specific nuclear backgrounds that confer particular desirable traits. The CMS inbred lines are created with specific combinations of genes for traits such as disease resistance, stress tolerance, and yield characteristics. This localized optimization of specific trait combinations in the cytoplasmic and nuclear genomes ensures that the resulting hybrids have both the adaptability to combine desirable traits and the reliability of consistent performance due to the uniform genetic background.
