In this paper we simulate the breeding process of marker-assisted introgressing a favorable QTL allele from “donor” to “recipient”. During this process, the foreground selection and background selection were made for introgression population simultaneously: foreground selection is making indirect selection of target gene by its closely linked two flanking markers, four selection methods includi...

Soybean is an important source of plant protein used in human diets. Cadmium (Cd) from agricultural soil a toxic metal for plants, including soybean. Furthermore, the cadmium taken up to seeds soybean and becomes risk animals by feed food chain. A method avoid this represented selection breeding lines/cultivars with genetic potential minimized accumulation. This work reports approach assisted D...

Marker-Assisted-Selection (MAS) is mainly important in situations, where the current accuracy of selection is low, e.g. traits with low heritability, limited, late-in-life, or afterslaughter recording. In veloand whizzo genetics schemes, the number of selection cycles per time period is minimized, which may increase rates of genetic gain dramatically. Genomic selection is used to obtain a high ...

Effect of flanking quantitative trait loci (QTL)-marker bracket size on genetic response to marker assisted selection in an outbred population was studied by simulation of a nucleus breeding scheme. In addition, genetic response with marker assisted selection (MAS) from two quantitative trait loci on the same and different chromosome(s) was investigated. QTL that explained either 5% or 10% of p...

Introduction I wish here to provide an overview of some past and more recent results on marker-assisted backcross breeding theory, and discuss the general consequences for marker-assisted selection and genotype building. Backcross breeding (MAB) is a well-known procedure for the introgression of a target gene from a donor line into the genomic background of a recipient line. The objective is to...
