Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker (morphological, biochemical or DNA/RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself.
Marker assisted selection (MAS) is also termed as marker aided selection and marker assisted breeding (MAB). It differs from gene assisted selection (GAS) which refers to the selection which is based on QTLs (quantitative trait locus or loci).
Aug 27, 2021 · Marker-assisted selection is a newly emerging approach due to which various problems of conventional breeding avoid and enhance the selection criteria of phenotypes with the selection of genes, either indirectly or directly.
Marker-Assisted Selection (MAS) is an efficient method to boost crop yield that, independent of the target environment, uses indirect selection at a very first stage of the yield to find QTLs (Quantitative trait loci) in lines, varieties, and populations for breeding [161 ].
Feb 2, 2008 · DNA markers have enormous potential to improve the efficiency and precision of conventional plant breeding via marker-assisted selection (MAS). The large number of quantitative trait loci (QTLs) mapping studies for diverse crops species have provided an abundance of DNA marker–trait associations.
Jul 9, 2020 · Marker-assisted selection (MAS) has emerged as a potential tool to achieve desirable results in plants with the help of molecular markers and improves the traits of interest in a short duration.
The idea behind marker assisted selection is that there may be genes with significant effects that may be targeted specifically in selectio n. Some traits are controlled by single genes (e.g. hair colour) but most traits of economic importance are quantitative traits that most likely are controlled by a fairly large number of genes.
Nov 15, 2012 · Marker-assisted selection (MAS) involves selecting individuals based on their marker pattern (genotype) rather than their observable traits (phenotype). The term ‘marker-assisted selection’ was first used by Beckmann and Soller in 1986 .
Marker-assisted selection (MAS) is based upon the establishment of a tight linkage between a molecular marker and the chromosomal location of the gene (s) governing the trait to be selected in a particular environment.
Apr 8, 2020 · Marker-assisted selection (MAS) involves selecting individuals based on their marker pattern (genotype) rather than their observable traits (phenotype). The term “marker-assisted selection” was first used by Beckmann and Soller in 1986.
