In modern agriculture, the reduction of environmental impact, ensuring both high and stable yield and high quality, is a primary goal. To avoid an excessive use of external inputs, without compromising crop performance, the increase of soil nutrient availability and nutrient use efficiency is fundamental in a sustainable potato production. In this framework, the use of plant biostimulants, such as

In the coming decades, feeding the expanded global population nutritiously and sustainably will require substantial improvements to the global food system worldwide. The main challenge will be how to produce more food with the same or fewer resources and waste less. Food security has four dimenespecially the case in Africa wheresions: food availability, food access, food use and quality, and food stability

Over 450 potato varieties and landraces are preserved as in vitro cultures by the Plant Biotechnology department of Estonian Crop Research Institute. This collection contains germplasm from various countries as well as old Estonian landraces. These potato accessions are periodically grown in the field for verification; however, this is not always sufficient to validate varieties and, in many cases

Marker-assisted selection (MAS) is more efficient with single locus marker methods than with the complex multi-locus AFLPTM system. Therefore, a method is described to convert AFLP markers into sequence characterised amplified region (SCAR) markers using arbitrary short primers that were generated based on AFLP markers linked to potato disease resistance genes. In the first step of this method, we

Bacterial wilt caused by Ralstonia solanacearum is the main bacterial disease in potato. Solanum commersonii Dun. (cmm; 2n = 2x = 24, 1 EBN) is a native species to southern Brazil, Uruguay and Argentina with desirable traits for introgressive hybridisation breeding into cultivated potato such as resistance to R. solanacearum. In Uruguay, successful crosses between cmm and Solanum tuberosum Group Tuberosum

Iron deficiency is a serious global issue, particularly in developing countries. Individuals are suffering from iron deficiency due to monotonous consumption of cereal based diets, which are unable to provide adequate amounts of iron. The majority of these people cannot afford a diversified diet, iron supplements and iron fortified food products. The development of iron biofortified potatoes could

The effects of container type on plant growth, yield and production cost of seed potatoes were investigated. Potato cultivars ‘Saebong’, ‘Geumsun’ (early-maturing) and ‘Haryeong’ (mid-maturing) were grown in four types of plant container: small (25 cm × 25 cm × 19 cm, L × W × H), medium (63 cm × 22 cm × 15 cm) and large (53 cm × 37 cm × 19 cm) plastic boxes and a styrofoam bed (100 cm × 52 cm × 31

Potato production requires intensive nitrogen (N) fertilization. To maintain yield and profitability, potato farmers must satisfy the need of the crops for N by applying fertilizer during the growing season. Petiole nitrate analysis and whole leaf total N test have been studied before to guide in-season N application, and both have strengths and weaknesses. Whole vine total N test has been discussed

Potato is the most important crop in Peru and late blight is the main disease affecting the crop. However, new varieties that are resistant to late blight often lack other traits that farmers and consumers prefer. Using participatory varietal selection, this study seeks to identify clones with high potential to become varieties with resistance to late blight but also feature a high marketable tuber

Petroleum-derived spray oils are long known to possess insecticidal activity. Lately, there is renewed interest in the use of mineral oils for the management of in-season spread of Potato virus Y (PVY) in seed potatoes. Mineral oils are environmentally benign and least prone to resistance development in target insect pests. Therefore, their use in integrated pest management is believed to be more sustainable

The effect of β-lactam antibiotics viz. cefotaxime, carbenicillin and cephalexin was evaluated on shoot organogenesis of potato cultivars ‘Kufri Pukhraj’ and ‘Kufri Chipsona 1’. Leaf and internodal explants from 21-day-old microshoots were cultured on pre-standardized medium for shoot organogenesis (basal Murashige and Skoog (MS) medium containing 10 μM AgNO3+10 μM 6-benzyladenine (BA)+15 μM gibberellin

A potential cause of the dissemination of the potato ring rot bacterium Clavibacter sepedonicus (Cs) is the use of automated seed potato cutters. The present study focuses on the question of whether disinfection practices are sufficient to prevent the transmission of Cs from contaminated machine parts to a new tuber lot. The disinfection efficacy was determined by establishing the culturability of

The drying kinetics and quality characteristics of three potato (Solanum tuberosum) cultivars (Agria, Granola and Marabel) cut into circles and squares were studied at 60 °C and 70 °C using a convective drier. Drying times were varied between 105 and 220 min depending on variety, shape and temperature and falling rate period was observed during hot air drying. Four mathematical models were fitted to

The paper describes the potato parental line breeding programme developed in Poland from the 1960s. The aim of the programme was to create parental forms useful for speeding up the breeding of new potato varieties and getting higher efficiency in directed selection for desired traits. The programme introduced new sources of resistance and quality traits into the Polish breeding pool by conducting research

Bt crops are the most important of the commercialised transgenic plants which were developed to combat destructive pests. Colorado potato beetle (CPB) is considered as a dangerous threat to potato production. In this study transgenic potato plants expressing cry3A gene were generated using Agrobacterium mediated transformation to combat the pest damage. Polymerase chain reaction (PCR) analysis confirmed

Rimsulfuron is commonly used to control common lambsquarters (Chenopodium album L.) and redroot pigweed (Amaranthus retroflexus L.) in potato (Solanum tuberosum L.) fields. Comparing rimsulfuron absorption and metabolism patterns in these two weed species with potato could provide crucial information to optimise herbicide application in the field. Hence, an experiment was conducted in Denmark and Iran

Transcription factors regulate gene expression depending on environmental and extracellular stimuli and signals from other cells. WRKY, MYB, bHLH and bZIP transcription factors (TFs) are one of the most important TF families in plants. Therefore, WRKY, MYB, bHLH and bZIP TFs in potato (Solanum tuberosum, St) genome under heat, salinity and drought stresses were investigated in terms of expression,

Each trial had a randomized complete block design with three replicates. There were 11 treatments

Every year, Agroscope examines nearly 300,000 tubers for the presence of viruses, as regulated for the certification of seed potatoes intended for Swiss growers. Since 2016, this examination has been performed via RT-qPCR on dormant tubers directly after harvest. This method offers fast results and eliminates the need for the use of Rindite, which is a toxic and polluting gaseous compound previously

This paper analyses the frequency of the consumption of table potatoes in Norway. The analysis shows that the frequency of potato consumption is higher in older cohorts than in younger, and it declines over the life cycle. This indicates that the total consumption will continue to decrease as older potato eating cohorts are replaced with younger cohorts who eat potatoes less frequently. This is bad

The objective of the present study was to establish whether exposure to temperatures of 55-70 °C results in eradication of the pathogen Clavibacter sepedonicus (Cs) in colonised potato tissue, in order to evaluate the efficiency of composting for disinfection of Cs-infected potato waste. Pre-sprouted potato tubers were inoculated and planted to produce Cs-colonised stem and tuber material. After incubation

To address the problem of dietary restraint of health-conscious people, a techno-feasible process for development of low-fat and high-fibre fabricated potato snack has been standardised. The product was optimised on the basis of fat and fibre content, browning index, hardness, crunchiness, and overall acceptability (OAA) by using the central composite rotatable design (CCRD) of response surface methodology

Acrylamide is an amide-type organic compound formed by the reaction of asparagine with reducing sugars (Maillard reaction) and is classified as a probable human carcinogen (Group 2A) by the International Agency for Research on Cancer. Potato chips are one of the foods that contribute most to dietary acrylamide intake, and despite a significant reduction in recent years thanks to changes in frying methods

To select potato genotypes tolerant to water deficit, systems to simulate this stress have been used. Polyethylene glycol (PEG) is the main osmotic agent used for this purpose, but it causes an excessively severe stress. However, it is difficult to carry out an experiment that aims to compare plant responses under water deficit by osmotic or matric induction, and, thus, few studies compare these stress-inducing

Over the past decades, two new strains of potato virus Y (PVYN-Wi (Wilga) and PVYNTN) have been the most widely distributed worldwide in potato crops (Solanum tuberosum L.). Effective resistance genes comprehensive against all the known strains of the virus are available in some commercial cultivars. However, not all resistance genes in cultivars have been challenged by the new PVY strains to confirm

The aim of this study was to assess the effectiveness of several treatments to control the spread of PVY (Potato virus Y) in seed potato crops. Field trials were conducted over a number of years in the Ardenne region of Belgium. Chemical treatments, including sprays of mineral oil, insecticide and a mix of them, were tested along with other treatments such as vegetal oil, plant slurries and Siliforce®

Potato is an important food security crop in Kenya. High prevalence of potato viruses is one of the major causes of low potato yields. Implementation of effective virus management strategies requires information on farmers’ perceptions and practices on virus epidemiology and control. To better understand farmers’ knowledge and practices in virus control and set possible pathways for intervention, a

The aim of this study was to determine the response of potato cultivars to Clavibacter sepedonicus (Cs) infection in a field experiment.

The experimental

Potato growers suffer losses due to potato soft rot and blackleg caused by pectinolytic bacteria of different species. These bacteria cause yield loss during cultivation and storage, and can be transmitted to the next generations through seed tubers. The prevalence of Pectobacterium atrosepticum has decreased over the last 20 years in Europe in favour of Dickeya solani and P. carotovorum subsp. brasiliense

In the coastal region of the Ganges Delta, rice is the predominant crop during the wet/kharif season and most of the land remains fallow during dry/rabi season due to soil salinity and irrigation water scarcity. Sustainable intensification of coastal saline land needs an improved package of practices which conserves soil moisture, facilitates early crop establishment, ensures profitability and has

Potato (Solanum tuberosum L.) is an important food and cash crop of India. An important constraint in potato cultivation in Deccan Plateau of India is non-availability of quality seed tubers. Many certified cultivars are readily available, but their quality check pertaining to viral infection is neglected. This study was made to determine the infection level of potato viruses in certified seed potatoes

The length of tuber dormancy of potato (Solanum tuberosum L.) is an important property of cultivars, which significantly determines the duration of storage period, the storage conditions, the economy of storage and the earliest time of planting. Potato cultivars can largely differ in the duration of dormancy period. Under temperate climatic conditions, longer dormancy is more advantageous. However

The most important potato viruses in Uganda are Potato virus Y (PVY), Potato leafroll virus (PLRV), Potato virus X (PVX), Potato virus S (PVS), Potato virus A (PVA) and Potato virus M (PVM). Utilization of R genes in breeding for resistance to viruses has not been explored in Uganda due to limited information on the prevalence of R genes in the available genotypes. This study aimed at identifying potato

When frying foods, volume changes appear as shrinkage that can affect their physical properties including density and porosity, which are both important factors for heat and mass transfer. Challenges faced in heat and mass transfer while processing foods are associated with shrinkage. It is thus necessary to analyse and quantify structural changes in foods (such as shrinkage) to better understand the
