WebMarker-assisted backcrossing for a single gene Marker-assisted backcrossing is the simplest form of MAS, in which the goal is to incorporate a major gene from an agronomically inferior source (the donor parent) into an elite cultivar or breeding line (the recurrent parent). The desired outcome is a line WebDNA markers. The term “marker-assisted selection” was fi rst used in the literature over two decades ago (Beckmann and Soller, 1986b) in relation to potential uses. A decade later, the use of the term became increasingly associated with reports on tagging genes with molecular markers (Fig. 1).
