Patent number: 6720137Abstract: A set of a plurality of microsatellite markers is provided for plant species of the tribe Triticeae, particularly Triticum aestivum. Each of the markers are constituted by a sequence tagged site (STS) defined by two primers, specific to a particular microsatellite sequence. Each primer has an average length of 20±3 bases and flanks the particular microsatellite sequence. Each of the microsatellite markers is formed by amplification of the microsatellite sequence by a polymerase chain reaction, to form markers of different length.Type: GrantFiled: May 1, 1998Date of Patent: April 13, 2004Assignee: Institut fur Pflanzengenetik und KulturpflanzenforschungInventors: Marion Roder, Jens Plaschke, Martin Ganal
