DNA markers linked to resistance locus of Marssonina leaf spot in poplars were found by bulked segregant analysis(BSA). The bulks consisted of individual with a extreme phenotype taken from a population of 91 F1 clones,which is a progeny of Populus deltoides Bartr.cv."Lux"(I-69/55)(Resistance) and P.euramericana cv.I-45(Susceptible). Out of 114 RAPD primers, four markers showed polymorphisms between the resistance-bulk and the susceptible-bulk.By using selective genotype linkage analysis,OPAI17-1550 and OPAI13-900 were found linked to the resistance locus. The genetic distances between the two markers and the resistance locus were 29.9cM and 37.4cM,respectively. |
