Abstract:
In the framework of PVS eradication from breeding materials of Czech potato cultivars, the systematic research was devoted to: susceptibility of cultivars, occurrence of PVS in imported and domestic materials, and to maintenance of virus-free basic grades potatoes on breeding stations. In the field-exposure trials was proved high level of susceptibility of most cultivars to PVS and by contraries, gradualy increased proportion of maintained virus-free cultivars of foreign, as well as domestic origin. Nevertheless severe infestation still persist in some of them. The contemporary situation with maintenance of virus-free basic material in CR was demonstrated.

Abstract:
The State Priekuïi Plant Breeding Institute (previously Wenden, Cçsis or Priekuïi Experimental and Breeding Station) started its operation in 1913. The main aims of research have remained the same for the last century: to provide knowledge on crop management and to create crop varieties suitable to local growing conditions and farming systems, acceptable to consumer requirements. Supply to farmers of high quality seed material of cereals, potato, pea, clover and grasses is an essential part of the scope. Overall, 31 crop species have been involved in a wide range of studies. More than 100 different crop varieties have been bred since the beginning of the 20th century. Potato varieties ‘Brasla’, ‘Agrie Dzeltenie’, winter rye variety ‘Kaupo’, pea varieties ‘Vitra’, ‘Retrija’, barley variety ‘Idumeja’ and several clover and grass varieties are widely grown in farmers’ fields. The first hulless barley variety in the Baltic States, ‘Irbe’, and winter triticale variety ‘Inarta’ have been bred in the Institute recently. Long-term crop rotation trials have been run for more than 50 years. A number of outstanding scientists and agronomists have worked in the Institute: potato breeders E. Knappe and V. Gaujers, cereal breeders J. Lindermanis, M. Gaiíe, and M. Sovere, grass breeders P. Pommers, A. Apinis, and I. Holms, pea breeder M. Vitjaþkova, researchers on crop management R. Sniedze and V. Miíelsons, research manager and director U. Miglavs and others

Abstract:
Abstract Although development of potato cultivars resistant to late blight has long been one of the primary goals of potato breeding programs, several different methods of field resistance evaluation have been used by potato breeders. Recently, within the EucaBlight network (www.euroblight.net), common methods of late blight evaluation have been agreed on, and these methods are currently highly recommended for use by all those interested in evaluating the resistance of the potato to late blight. Here, we describe a method of evaluating potato resistance in field conditions routinely used at Młochów Research Center, which is compliant with recommendations of the EucaBlight protocol.

Abstract:
The first potato varieties that reached the territory of Latvia were empirically selected clones from genetically diverse material brought from South America to Europe. In the 19th century, when agricultural production rapidly developed, the demand for high yielding potato varieties suitable to local growing conditions increased. Therefore, potato variety evaluation trials were set up. Scientifically- based potato breeding in Latvia was launched by P. Knappe. The potato breeding programme in Priekuïi Plant Breeding Station was started in 1931, and has still continued. Several breeding methods were used by potato breeders Ç. Knape, V. Gaujers, G. Bebre and others in Priekuïi. Potato breeding for short periods was carried out in several other places in Latvia: Stende, Carnikava, and Lejaskurzeme. The method of elimination of diseases in potato seed material and high quality seed material production was implemented in Priekuïi. More than 60 potato varieties have been created in Latvia, some of them were and still are in demand in agricultural production.

Abstract:
Potato early dying (PED), also known as Verticillium wilt, caused by Verticillium dahliae, is a seasonal yield-limiting disease of potato worldwide, and PED-resistant cultivars currently represent only a small percentage of potato production. In this study, we developed a real-time quantitative polymerase chain reaction (Q-PCR) approach to detect and quantify V. dahliae. The efficiency of the designed primer pair VertBt-F/VertBt-R, derived from the sequence of the β-tubulin gene, was greater than 95% in monoplex Q-PCR and duplex (using Plexor technology) procedures with primers PotAct-F/PotAct-R, obtained from the sequence of the actin gene, designed for potato. As few as 148 fg of V. dahliae DNA were detected and quantified, which is equivalent to five nuclei. Q-PCR detected V. dahliae in naturally infected air-dried potato stems and fresh stems of inoculated plants. Spearman correlations indicated a high correlation (upward of 80%) between V. dahliae quantifications using Q-PCR and the currently used plating assays. Moreover, Q-PCR substantially reduced the variability compared with that observed in the plating assay, and allowed for the detection of V. dahliae in 10% of stem samples found to be pathogen free on the culture medium. The described Q-PCR approach should provide breeders with a more sensitive and less variable alternative to time-consuming plating assays to distinguish response of breeding lines to colonization by V. dahliae.

Abstract:
Abstract The efficiency of breeding new potato cultivars may be increased by pre-breeding that is by developing parental lines, which have new traits, not present in the genetic pool available for breeders or have new combinations of genes, or have improved level of economically important traits. The use of parental lines in commercial breeding programs is expected to ensure the biological progress in the newly created cultivars of potato. At the beginning, the development of parental lines in Młochów Research Center of Plant Breeding and Acclimatization Institute - National Research Institute (IHAR-PIB) was focused on resistance to viruses and later on resistance to late blight and other pathogens. The procedures of selecting resistant parental lines are described. These procedures were initially based on purely phenotypic tests for resistance, which lately were supplemented with marker assisted selection (MAS) applying molecular markers linked with some resistance genes.

Abstract:
Correct identification of potato cultivars and selections is essential to a large and diverse user group. This group includes curators of germplasm repositories, breeders and other researchers, certification program officials, commercial growers, processing industry managers and for some cultivars, the public. Agencies involved in cultivar registration and plant breeders' rights (or patenting) also have a vested interest in correct identification. DNA fingerprinting is an important tool that can be used to describe new or existing cultivars, verify cultivar identity, and resolve cultivar mixtures. Gel-based fingerprints are usually preferred because they are visual and within the technical capacity of most molecular laboratories. In this study, a multiplex PCR protocol "Multiplex SUP" and an improved version "Multiplex SUPN" were developed using four primer pairs (STEM0014 and genes of starch synthase, patatin, and UDP-glucose pyrophosphorylase). The agarose-gel-based Multiplex SUP was successfully used in identifying cultivars from blind samples in a collaborating laboratory, and in pilot tests to verify the identity of introduced cultivars for seed potato production. The Multiplex SUPN, using native polyacrylamide gel electrophoresis (PAGE) with GelRed or ethidium-bromide staining, generated more than 38 polymorphic markers among the potato cultivars tested. The method distinguished 116 cultivars that included many of the public potato cultivars registered in Canada and several protected cultivars that were fingerprinted with permission. The Multiplex SUPN-PAGE method is user friendly and effective, and is recommended for routine potato cultivar verification and identification.

Abstract:
Potatoes destined for crisping are normally stored above 8 degrees; below this glucose accumulates leading to very dark fry colors and potential acrylamide build up. Unfortunately, sprouting occurs above 4 degrees and impacts product quality, necessitating the use of sprout suppressant chemicals. Therefore, a goal of breeders is to develop potatoes with excellent fry color, which is maintained under storage below 8 degrees. Genomic or marker-assisted selection offers an opportunity to improve the efficiency of potato breeding and thereby assist breeders in achieving this goal. In this study, we have accumulated fry-color data on a large population of potato lines and combined this with genotypic data to carry out a GWAS and to evaluate accuracy of genomic prediction. We were able to identify a major QTL on chromosome 10 for fry color, and predict fry color with moderate accuracy using genome-wide markers. Furthermore, our results provide evidence that it is possible to identify a small subset of SNPs for processing characteristics that can give moderate predictive ability, albeit lower than that achieved with genome-wide markers.

Abstract:
Antioxidants, such as polyphenols and carotenoids, are present in potato and reported to have positive effects on human health. For Ecuadorian landraces there is a lack of data on these compounds. The present study aims 1) to characterize potato landraces from three areas in Ecuador for dry matter, total polyphenol and total carotenoid contents and 2) to determine if farmer preferences for certain landraces are based on characteristics related to nutritional value. We evaluated 23 potato landraces collected from farmer’s fields and organized workshops in the areas to collect information on the preferences of local farmers. We found varying levels of dry matter, total polyphenol and total carotenoid contents among Ecuadorian potato landraces, some even comparable to improved varieties. The extent of the use of these potato landraces by farmers and breeders is discussed.Accepted for publication: June 30, 2012.

Abstract:
The Ry adg allele is widely used by breeders to confer extreme resistance to all strains of PVY. However, the necrotic strain has increased recombination resulting in recent considerable losses in productivity. Thus far, not all necrotic recombinant strains of PVY have been tested for their reaction to the Ry gene. The objective of this study was to identify potato clones carrying the resistant allele and to assess their reaction to the following recombinant strains: NTN (PVY NTN), Wilga (PVY N-Wi), and "curly top" (PVY E). Advanced clones from the potato breeding program at Universidade Federal de Lavras were evaluated through a specific molecular marker for the Ry adg allele. The clones carrying the resistance allele were grafted on tobacco plants infected with necrotic recombinant strains of PVY. The clones carrying the allele for resistance to PVY were not infected with any of the recombinants during the grafting test. These results confirm that resistance to necrotic recombinant strains has not yet been overcome and that the Ry adg allele also confers resistance to the three recombinant strains tested.

Abstract:
Several enhancements to the conventional potato breeding are possible though they have encouragement as well as limitations. I n this direction, the marker-assisted selection may be utilized to stack major genes as well as QTLs. Whereas the genetic transformation and genome editing methods accelerate the process of ricking of genes/transgenes. Moreover, these methodologies supplemented with the next-generation sequencing (NGS) platforms and pipelines further aid in reaching the potato ideotype. Here, we overviewed the critical topics that are related to potatoes, from general background, breeding behavior, breeding approaches employed to the potato improvement. Overall, this information complied might serve as background information that is important for potato breeders.
