Diploid genotype DW.84-1457, highly resistant to potato leafroll virus (PLRV)

Potato Research, 1994
The diploid clone DW.84-1457 which has outstanding resistance to potato leafroll virus (PLRV), has been selected at the Mlochow Centre of the Institute for Potato Research. It has in its pedigree PLRV-resistant clones from the Max Planck Institute nos. MPI 44.1016/10, MPI 44.335/130 and MPI 49.540/2.

Progeny tests to identify diploid potato clones homozygous at loci controlling resistance to PLRV

Potato Research, 1998
Using potato parental lines homozygous at a locus or loci controlling resistance to potato leafroll virus (PLRV) can give advantages in the selection of resistant forms. In order to identify homozygous diploid clones their test-cross families were evaluated.

Field assessment of imidacloprid to reduce the spread of PVY° and PLRV in potato

American Journal of Potato Research, 1999
A three year field study conducted at the Potato Research Centre in Fredericton, New Brunswick, showed that imidacloprid applied in furrow at planting or twice to the foliage in mid July could result in a limited reduction of PLRV spread in the potato crop. Tests did not determine any significant effect on the reduction of the spread of PVY.

Transfer of PLRV resistance fromSolanum verrucosum Schlechdt to potato (S. tuberosum L.) by protoplast electrofusion

Potato Research, 2000
Somatic fusions between an accession of the diploid wild speciesSolanum verrucosum and a dihaploid S.tuberosum genotype were produced in order to incorporate resistance to potato leafroll virus (PLRV). In total 15 somatic hybrids out of 16 regenerants were obtained.

Comparison of nucleotide sequences from three potato leafroll virus (PLRV) isolates collected in Brazil

American Journal of Potato Research, 1999
Polymerase chain reaction linked automated sequencing was used to compare the relatedness of Brazilian (BR) potato leafroll luteovirus (PLRV) isolates. By comparing PLRV genomic sequences from Holland, Poland, Canada, Scotland, and Australia (GeneBank), three primer pairs were designed and made that would hybridize to all five isolates, and amplifying ...

Myzus persicae (Sulzer) in diffuse light and dark rustic storages and resultant PLRV transmission

American Potato Journal, 1983
Population levels ofMyzus persicae (Sulzer) were studied on potato tubers in diffuse light and dark rustic storage houses in Peru. No differences in numbers of aphids/sprouted eye on potatoes infested naturally during storage in diffuse light or darkness were observed.
