| 1 | Using of molecular markers to combine alleles conferring resistance of potato to potato leafroll virus accumulation | Waldemar Marczewski (Leader) | 09.2004 - 02.2007 | A novel locus for potato resistance to potato leafroll virus (PLRV) was characterized by inheritance studies and molecular mapping. Two allelic or tightly linked genetic factors at the PLRV.4 locus on potato chromosome XI control resistance to potato leafroll virus accumulation. | 1.

| 4 | Identification of molecular markers for genes of the resistance to pathogens in the potato | Waldemar Marczewski (Leader) | 1998 and after | Molecular markers for genes of the resistance to potato virus M and potato virus S were identified in potato. Two new loci for resistance to potato virus M, Gm and Rm, have been mapped in potato. Gm was mapped to a central region on chromosome IX. The locus Rm was placed on the short arm of chromosome XI. The potato virus S resistance gene Ns was mapped to potato chromosome VIII. | 1.

| 5 | The effects of genetic variability within Potato virus Y (PVY) population on pathogenicity and virulence of different virus isolates and their interactions with vectors | Jerzy Syller (Leader) | 05.2007 - 05.2010 | The objective of the project is to characterize aphid transmissibility and relationships with aphid transmissibility various host plants of geographically different isolates/strains of PVY. | 1.

| 6 | The relationships between viruses, aphids and plants during the infection process and in the pathogenesis of potato virus diseases were studied. | Jerzy Syller (Leader) | 1998 and after | Three essential components of resistance to PLRV in potato, i.e. Resistance to infection, restriction of virus multiplication and inhibition of virus movement to tubers, were studied. Long-distance movement of Potato leafroll virus to tubers were inhibited in potato genotypes expressing combined resistance to infection, virus multiplication and accumulation. | 1.

| 7 | Control of Potato mop-top virus in the Nordic and Baltic Sea region. | Ewa Zimnoch-Guzowska (Leader) | 01.2005 - 12.2008 | Occurrence of Potato mop-top virus (PMTV) was monitored in Poland. No PMTV was found in Poland so far. From 2004 to 2007, a total of 52 cultivars (5200 tubers), 24 cultivars (2400 tubers), 59 cultivars (5900 tubers) and 21 cultivars (2200 tubers) were examined for spraining symptom, respectively, in the northern and central Poland. Among them, 110 tubers representing 9 cultivars were found with necrotic symptom on tuber flesh. ELISA tests revealed the possible presence of PMTV in some samples. However, RT-PCR using PMTV-specific primers showed negative results on some tested samples. The occurrence of PMTV in Poland is continuously monitored in 2008. | 1.

| 9 | Examination of viruses causing necroses of potato tubers: Tobacco rattle virus (TRV) and Potato mop-top virus (PMTV) | Zhimin Yin (Leader) | 01.2000 and after | Two viruses causing necroses of potato tubers-PMTV and TRV were investigated. So far, no PMTV was detected in the tested tuber samples with necrotic symptom, though some exhibited elevated absorbance level by ELISA using PMTV antibody. In a few samples the presence of TRV were confirmed by ELISA and RT-PCR with primers specific to TRV. Screening potato cultivars resistant/tolerant to TRV is in progress. | 1.

| 10 | Inheritance of the resistance to potato leafroll virus (PLRV). | Bogdan Flis (Leader) | 1998 and after | A major QTL PLRV.1 for resistance to Potato leafroll virus (PLRV) is located in a resistance hotspot on potato chromosome XI and is tightly linked to N-gene-like markers. Two allelic or tightly linked genetic factors at the PLRV.4 locus on potato chromosome XI control resistance to Potato leafroll virus accumulation. | 1.

| 11 | Analysis of strains of potato viral pathogens and the reaction of different potato genotypes to virus infection. | Krystyna Michalak (Leader) | 1998 and after | Different strains of potato viral pathogens were characterized biologically and/or molecularly. The selected virus strains of PVY, PVM, PVX, PVS and PLRV respectively were used to inoculation potato plants of different genotypes. The reaction of potato plants to virus infection was studied using plants grown in greenhouse and/or in the field. | 1.
