Project Title: 
Search for Molecular Markers in Potato Germplasm for PTNRD Expression
Project Abstract: 
  Potato tuber necrotic ringspot disease (PTNRD) is a tuber deformity associated with infections by potato virus Y strain-NTN (PVYNTN). It negatively impacts tuber quality, reduces trade opportunities, and poses a serious threat to potato seed and commercial production worldwide. Our research goal is to develop reliable molecular markers that will allow breeders to rapidly and economically screen early selections to eliminate PTNRD-susceptible clones. The cultivars ‘Waneta’ and ‘Pike’ express severe and mild PTNRD symptoms, respectively, when infected with PVYNTN isolate NY090029. An F1 Waneta x Pike population is being used to map the genes controlling PTNRD expression.
