Sažetak
The inheritance of resistance to downy mildew of sunflower was investigated in three mapping populations. From each cross 73 to 75 F3 families were produced. The resistance of plant material to downy mildew was evaluated by the whole seedling inoculation technique. F3 families were studied using several PCR and two CAPS markers for resistance gene analogues (RGAs) at Pl6 locus. Seven haplotypes, in coupling or repulsion phase with resistance, five dominant and two co-dominant, were mapped for each mapping population. The results of heterogeneity test between recombination fractions for each marker pair among three families, permitted the construction of composite map. Mapping results are consistent, regardless on the parental lines used as sources of resistance genes.
