Andean and Ordinary Strains of Potato Virus S Infecting Potatoes in Southern Kazakhstan

The spatial and temporal distribution of Potato virus S (PVS) and Potato virus X (PVX) was studied in two trials within each of four commercial fields of seed potato var. Russet Burbank in Tasmania, Australia. In the first trial (plots) 20 leaflets were collected from each of 49 plots (each approximately 8 m wide by 10 m long), with plots arranged in a 7-×-7 lattice. In the second trial (transects), leaflets were collected at 1-m intervals along seven adjacent, 50-m long rows. The mean incidence of PVS increased during the season by 5.2% in one of four plot trials and 25.5% in one of four transect trials. The mean incidence of PVX increased during the season by 10.1%, in one of two transect trials. Spatial Analysis by Distance IndicEs and ordinary runs analysis detected aggregation of PVS infected plants early in the season in one and two fields respectively, suggesting transmission during seed-cutting or during planting. An increase in PVS incidence mid- to late season in one field was associated with aggregation of PVS along, but not across rows, which may be related to the closer plant spacing within rows and hence increased potential for mechanical transmission along rows. Results suggested limited spread of PVS and PVX occurred within crops during the season. Accepted for publication 9 April 2007. Published 26 July 2007.

Resistance To Viruses

Molecular markers within or close to genes of interest play essential roles in marker-assisted selection. PCR-based markers have been developed for numerous traits in different plant species including several genes conferring resistance to viruses in potato. In the present work, rapid and reliable approaches were developed for the simultaneous detection of Ryadg and Ry-fsto, Ns, and PLRV.1 genes conferring resistance to Potato virus Y, Potato virus S and Potato leafroll virus, respectively, on the basis of previously published and newly modified markers. The sequence characterized amplified region (SCAR) markers for Ryadg, Ns and PLRV1 and the newly modified cleaved amplified polymorphic sequences (CAPS) marker for Ry-fsto were amplified in one PCR reaction which could simply characterize Ryadg and PLRV.1 resistance. Additional digestion of amplicons with EcoRV and MfeI for genotyping the Ry-fsto and Ns resistance genes, respectively, was needed. The effectiveness of genotyping in triplex and tetraplex PCRs was tested on 35 potato varieties used for potato seed production and breeding programs.
