 The Rx locus in potato confers extreme resistance to PVX. In the F1 progeny of crosses between the PVX-susceptible cultivar Huinkel and the cultivar Cara (Rx genotype) there was a 1 : 1 segregation of PVX resistance, indicating that Rx in Cara is present in the simplex condition. Using potato and tomato RFLP markers, we mapped Rx in Cara to the distal end of chromosome XII at a different position to the previously mapped Rx1 locus. To generate a high-resolution linkage map in the vicinity of… CONTINUE READING
