Identification of molecular markers linked to Rdr1, a gene conferring resistance to blackspot in roses

Blackspot resistance in the tetraploid rose genotype 91/100–5 had been characterised previously as a single dominant gene in duplex configuration. In the present study a tetraploid progeny (95/3) segregating for the presence of the blackspot resistance gene Rdr1 were screened with 868 RAPD and 114 AFLP primers/primer combinations. Seven AFLP markers were… CONTINUE READING
