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), … Meer weergeven The majority of MAS work in the present era uses DNA-based markers. However, the first markers that allowed indirect selection of a trait of interest were morphological markers. In 1923, Karl Sax first reported … Meer weergeven The gene of interest directly causes production of protein(s) or RNA that produce a desired trait or phenotype, whereas … Meer weergeven Morphological markers are associated with several general deficits that reduce their usefulness including: • the … Meer weergeven There are several indications for the use of molecular markers in the selection of a genetic trait.
