GpaXIltar originating from Solanum tarijense is a major resistance locus to Globodera pallida and is localised on chromosome 11 of potato [PDF]

, 2009
Resistance to Globodera pallida Rookmaker (Pa3), originating from wild species Solanum tarijense was identified by QTL analysis and can be largely ascribed to one major QTL.

Inter and Intra Variation of Potato Yellow Vein Virus in Three Potato Species From Colombia / Variación Inter e Intra de Potato Yellow Vein Virus en Tres Especies de Papa de Colombia

Revista Facultad Nacional de Agronomía Medellín, 2015
. Potato yellow vein virus (PYVV), (family Closteroviridae, genus Crinivirus) is a re-emergent virus in Andean countries. Low inter-isolate variation has been reported for PYVV CP gene, but there are no reports for intra-isolate variation.

Genetic improvement for yield and tuber size in Andigena potatoes (Solanum tuberosum subsp andigena) after one cycle of recurrent selection

The Indian Journal of Agricultural Sciences, 2012
Improvement of Andigena genotypes for tuber characters was attempted by making Andigena × Andigena crosses. Andigena accessions could be considerably improved for characters like yield and tuber size by crossing among themselves. Progenies of different cross types like full-sibs, half-sibs, back crosses and cross between unrelated parents among the ...

Pectobacterium carotovorum subsp carotovorum can cause potato blackleg in temperate climates [PDF]

, 2008
It is well established that the pectinolytic bacteria Pectobacterium atrosepticum (Pca) and Dickeya spp. are causal organisms of blackleg in potato. In temperate climates, the role of Pectobacterium carotovorum subsp. carotovorum (Pcc) in potato blackleg,

Recessive and Dominant Genes Interfere with the Vascular Transport of Potato virus A in Diploid Potatoes

Molecular Plant-Microbe Interactions, 2000
Resistance to Potato virus A (PVA) was examined in a diploid cross involving Solanum tuberosum subsp. andigena as a resistance source. Hypersensitive resistance (HR) to PVA cosegregated with extreme resistance (ER) to Potato virus Y conferred by the ...

Mapping loci for chlorosis associated with chlorophyII b deficiency in potato [PDF]

, 2008
About 30% of the potato plants from a (Solanum tuberosum × S. berthaultii) × S. tuberosum backcross population had chlorotic, malformed leaves; but a gradation in symptom severity suggested regulation by more than one gene.

Genetic diversity of native potatoes (Solanumspp.) conserved in landraces from Peru

Revista Peruana de Biología, 2014
This paper analyzes the genetic diversity of 79 accessions of native potato varieties (Solanum spp.) using 18 microsatellite markers. A random sample from Ayacucho, Cajamarca, Cusco, Huancavelica and Puno from "chacras" of farmers who collaborated with ...

Molecular marker analysis of 24- and 25-chromosome plants obtained fromSolanum tuberosumL. subsp.andigena(2n= 4x= 48) pollinated with aSolanum phurejahaploid inducer [PDF]

Genome, 2002
Clones with 24 or 25 chromosomes were obtained by pollinating an Andean cultivated tetraploid potato (Solanum tuberosum subsp. andigena clone 94H94, 2n = 4x = 48) with the Solanum phureja haploid-inducer clone 1.22. Their genetic composition was analyzed in an RAPD assay using 135 decamer primers and in an RFLP assay using 45 single-copy DNA probes. In

Pest categorisation of Septoria malagutii

EFSA Journal, Volume 16, Issue 12, December 2018., 2018
Abstract The Panel on Plant Health performed a pest categorisation of Septoria malagutii, the causal agent of annular leaf spot of potato, for the EU. The pest is a well‐defined fungal species and reliable methods exist for its detection and identification. S. malagutii is present in Bolivia, Ecuador, Peru and Venezuela.
