A consensus map of chromosome 6R in rye (Secale cereale L.)

Abstract

Four F2 mapping populations derived from crosses between rye inbred lines DS2xRXL10, 541xOt1-3, S120xS76 and 544xOt0-20 were used to develop a consensus map of chromosome 6R. Thirteen marker loci that were polymorphic in more than one mapping population constituted the basis for the alignment of the four maps using the JoinMap v. 3.0 software package. The consensus map consists of 104 molecular marker loci including RFLPs, RAPDs, AFLPs, SSRs, ISSRs, SCARs, STSs and isozymes. The average distance between the marker loci is 1.3 cM, and the total map length is 135.5 cM. This consensus map may be used as a source of molecular markers for the rapid development of new maps of chromosome 6R in any mapping population. © 2008 by the University of Wrocław.
