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.
Molecular breeding is the application of molecular biology tools, often in plant breeding [1] [2] and animal breeding. [3] [4] In the broad sense, molecular breeding can be defined as the use of genetic manipulation performed at the level of DNA to improve traits of interest in plants and animals, and it may also include genetic engineering or gene manipulation, molecular marker-assisted ...
The selection in these crops is restricted to the material introduced from other sources, such as field plantations. The improvement of asexually propagated plants through induced mutations has distinct advantages and limitations. Any vegetative propagule can be treated with mutagens and even a single desirable mutant or a part of a mutated ...
This technology has many applications in quality control (QC) genotyping, quantitative trait locus (QTL) mapping, marker-assisted selection (MAS), and allele mining. For example, the KASP platform has been used in qualitative control analyses for maize. In maize, homogeneity is important in cultivating the crops that the grower had selected ...
Marker assisted selection can also be employed as a diagnostics tool to facilitate selection of progeny who possess the desired trait(s), greatly speeding up the breeding process. [57] This technique has proven particularly useful for the introgression of resistance genes into new backgrounds, as well as the efficient selection of many ...
GS is a method proposed to address deficiencies of marker-assisted selection (MAS) in breeding programs. However, GS is a form of MAS that differs from it by estimating, at the same time, all genetic markers, haplotypes or marker effects along the entire genome to calculate the values of genomic estimated breeding values (GEBV).

Particular traits such as color, may be controlled by just a few genes. Qualitative traits (requires less than 2 genes) such as color, can be identified using MAS (marker assisted selection). Once a desired marker is found, it is able to be followed within different filial generations. An identifiable marker may help follow particular traits of ...
Mutation breeding, sometimes referred to as "variation breeding", is the process of exposing seeds to chemicals, radiation, or enzymes [1] [2] in order to generate mutants with desirable traits to be bred with other cultivars.
