利用马铃薯与白索茄杂交获得的二倍体回交群体对马铃薯Y病毒（PVY）表现单基因显性过敏。我们建议用符号Ny（tbr）表示该基因座，因为携带该基因的植物在接种PVY后发生坏死，而该等位基因起源于S。马铃薯在LOD = 2.72处，该基因定位于TG316和TG208之间的染色体IV。该位置不对应于马铃薯中的任何其他定位的抗性基因。
A diploid backcross population derived from a cross between Solanum tuberosum and Solanum berthaultii segregated for monogenic dominant hypersensitivity to Potato virus Y (PVY). We propose the symbol Ny(tbr) for this locus because plants carrying this gene develop necrosis after inoculation with PVY and the allele originated in S. tuberosum. The gene mapped to chromosome IV between TG316 and TG208 at LOD = 2.72. This location does not correspond to any other mapped resistance genes in potato.
