Marker-Assisted Technique

Marker-assisted technique , also called as marker-assisted breeding (MAB), avoids this problem by using genetic markers that are linked to the desired trait. Once they are able to identify a genetic sequence that is always linked to disease resistance they can. MAS can be more efficient, effective and reliable than phenotypic selection. Furthermore, MAS can shorten the development time of varieties significantly, so in some cases it will be more cost effective than selection based on phenotypes. MAS also allow the breeding of complex traits not feasible through previous conventional methods. Although certainly not the silver bullet for all problems, MAS is a promising approach to conventional plant breeding
