We isolated and investigated the starch of six potato cultivars (Solanum tuberosum), grown in the Andean region in the south of Colombia, to determine their physicochemical properties. The potato cultivars are known by their common names as Mambera, Ratona, Pastusa, Capiro, Unica and Roja-huila. The minerals, amylose content, water absorption and water solubility of the starches were evaluated. Morphology

Mini tubers are the starting materials of a disease-free seed potato production scheme. Low multiplication rates as well as non-homogenous tuber size distribution are considered the main constraints of a conventional mini tuber production system. In recent years, an aeroponics production system has been developed to overcome the aforementioned problems. It has previously been observed that this system

We investigated the effect of inoculation with the plant-growth-promoting rhizobacterium Azospirillum brasilense Sp245 under aeroponic conditions on the quality and performance of minitubers of potato (Solanum tuberosum L. cvs. Nevsky and Kondor). In vitro-grown microplants were planted in an aeroponic system, and after 3 weeks of growth, the bacteria were added to the potato nutrient solution. We

The study was carried out to assess the impact of climate change on potato productivity to develop adaptation strategies in Punjab, using crop growth simulation models for future climate scenarios (2030, 2050 and 2080) under representative concentration pathways (RCPs) 4.5 and 6.0. Three potato cultivars belonging to distinct maturity groups, late (Kufri Badshah), medium (Kufri Jyoti) and early (Kufri

Potato (Solanum tuberosum L.) is an important crop in Uganda but production is low. There is not a well-functioning official seed system and farmers use potato tubers from a previous harvest as seed. This study investigated how effectively the seed technology positive selection enhanced yield and underlying crop characteristics across multiple seasons, compared to the farmers’ selection method. Positive

This study evaluated the use of sodium metabisulphite (SMB) and ascorbic acid (AA) to control browning in ready-to-eat processed potatoes during 8 months of storage. The experiment was carried out using the production line of a commercial potato processing business located in the state of Paraná, Brazil. The following treatments were tested in the immersion process of the potatoes: T1 (control, without

Climate change is a threat to agriculture but also presents opportunities and requires adaptation strategies. In many countries adequate meteorological data is lacking, so this is where NASA weather data are of assistance. We aimed to develop a generic and easily applicable approach to calculate the effect of climate change on potato yields and water need. We therefore used the NASA-Langley-Gaisma

Crop models can be used to estimate yield, water requirements and plant nutrition requirements under different conditions. This study examines the performance of the SSM-iCrop2 model in terms of predicting tuber yield, phenological stage and water requirement of potato (Solanum tuberosum L.) under changing climate circumstances in Iran. Simulation of potato growth, tuber yield and water requirement

The potato cyst nematodes (PCN) Globodera rostochiensis and G. pallida are among the most important pests causing significant yield loss in potato production. Cultivating resistant cultivars of potato is the most effective and environmentally safe method for protecting potato crops against nematodes. However, widespread cultivation of cultivars resistant to G. rostochiensis can affect the reproduction

The chemical composition, total antioxidant capacity (TAC) and total flavonoids were assessed in fifty-two Andean potato cultivars, with local indigenous names, from Bolivia, comprising five species and one subspecies. Moisture content ranged from 63 to 81%, and on a fresh-weight basis, ash content from 1 to 2%, protein content from 3 to 11%, carbohydrate content from 9 to 35% and total lipids ≤ 0

Arbuscular mycorrhizas (AMs), formed between AM fungi and vascular plants, are a widespread mutualistic symbiosis where fungi colonize root cells, transfer mineral nutrients (mainly phosphate) and, in turn, obtain carbon of a photosynthetic origin. To explore the possible roles played by antioxidant enzymes in the roots and shoots of AM-inoculated potato cultivars, a field experiment was conducted

Phytoplasmas in the aster yellows (16SrI), clover proliferation (16SrVI) and stolbur (16SrXII) groups have a wide host range with common hosts. In the current study, specific primers based on the 16-23S rRNA spacer region were designed and optimised for the detection and identification of phytoplasmas in these groups in a multiplex nested PCR assay. Fifty-two phytoplasma symptomatic potato plants were

The field efficacy of liquid formulations of Pseudomonas fluorescens, Purpureocillium lilacinum and Trichoderma viride was investigated against natural populations of potato cyst nematodes (PCNs) Globodera rostochiensis and Globodera pallida. Two field experiments were conducted using these biocontrol agents applied as seed treatment (ST) at 1 L t−1 of seed and soil drenching (SD) at 5 L ha−1. Their

Potato (Solanum tuberosum L.) is considered a drought-sensitive crop species, although cultivar-dependent differences in tolerance have been described. The extent of drought-induced tuber yield decreases is considered the main criterion for potato tolerance to drought. In this study, eighteen closely related potato cultivars were subjected to drought stress, and among them, two groups with contrasting

The use of a cold storage plant for reducing perishable food losses is insufficient in developing and underdeveloped countries because of required infrastructure and investments. For this reason, many producers continue to store foods with traditional methods, which can lead to considerable food loss. At this point, the relationship between the financial loss due to perishable foods and the costs of

The nitrite and nitrate in foodstuff and their associated harmful effects are of great concern for human health. More than 80% of human nitrate intake is attributed to the consumption of vegetables and fruits, and for this reason, more attention should be paid to the consumption of such foodstuffs and reduction of nitrate intake. Therefore, this study aimed to determine the variation of nitrate and

Recently, a hybrid breeding system was developed for diploid potato. We compared performance of diploid hybrids with commercially available tetraploid cultivars. Therefore, seedling tubers were produced from true hybrid seeds in field conditions. In the subsequent year, diploid hybrids grown from seedling tubers showed a yield potential comparable with commercial tetraploid cultivars: the highest yielding

Protection of the environment is one of the most important issues of politics in many countries. The food industry generates large amounts of waste, which can be further managed using biotechnological processes. The potato industry is one of the branches which generates a huge amount of waste that is burdensome for the environment. In the production process of potato starch, chips and alcohol, the

Potato (Solanum tuberosum L.) is considered to be one of the most prominent nongrain food crops throughout the world that can be regarded as most affordable and most accessible food to provide numerous health benefits. Potential role in improving human health is attributed to presence of wide range of phytonutrients in potatoes viz., polyphenols, anthocyanins, carotenoids, ascorbic acid and proteins

Fresh-cut potatoes are a good option for consumers who want a healthy diet but have limited time to prepare meals. However, the polyphenol oxidase enzyme released during cutting of potatoes reacts with phenolic compounds, causing browning. Cold storage can slow down this reaction to some extent, but it cannot prevent it. Enzymatic browning lowers polyphenol content and reduces consumer appreciation

The demand for processing potatoes has been increasing in Japan since the 1970s due to changes in eating habits from fresh potatoes to processed products. However, domestic supply of potatoes has not changed for the past five decades and the country is not self-sufficient in potato production. Understanding potato crop and soil-environmental yield limiting factors at growers’ management level is important

Potato starch was subjected to heat moisture treatment (HMT) in which the temperature and moisture content were varied. Two different levels of moisture content (30 and 35%) and temperature (100 and 120 °C) were selected. The crystallinity of the starches decreased after HMT, as confirmed by both X-ray diffraction (XRD) and Fourier Transform Infra-Red (FT-IR) analysis, and the XRD pattern of native

Potato common scab caused by bacterial pathogen Streptomyces scabies (Thaxt.) Waksman & Henrici is one of the most important diseases of potato (Solanum tuberosum L.) worldwide. Currently, the most effective and desirable method to control common scab is through the use of resistant cultivars. In order to decipher the genetic control of resistance to common scab disease in Canadian potato germplasm

Much of the nitrogen in crop fertiliser is degraded before acquisition. Technologies that stabilise urea-nitrogen minimise this. Degradation also specifically reduces the amount of ureic amine that many fertilisers initially contain, which is important because this nitrogen form has unique beneficial effects on plants. To investigate mechanisms whereby urea stabilisation increases potato tuber yield

Long-term storage of tubers in refrigerated and non-refrigerated storage induces sprouting and other degradative quality changes, thus making them unacceptable for consumption. There are already known effects of packaging materials on storability of fresh produce while optimization of package with respect to temperature for shelf life enhancement of tubers is still needed in the case of deficient storage

Precision agriculture is a farming management concept based on observing, measuring and responding to inter- and intra-field variability in crops. In this paper, we focus on responding to intra-field variability in potato crops and analyse variable rate applications (VRAs). We made an overview of potential VRAs in potato crop management in The Netherlands. We identified 13 potential VRAs in potato

Developing cultivars that use nitrogen more efficiently is a sustainable strategy for reducing nitrogen use in crop production. To assess the genetic diversity for nitrogen use efficiency (NUE) and related traits in potato, a total of 97 (88 for the Western-European market and 9 Ethiopian) cultivars were evaluated at two nitrogen levels (40 kg/ha and 120 kg/ha) for 24 quantitative traits in Debre-Tabor

Potato tubermoth (PTM) Phthorimaea operculella (Lep.: Gelechiidae) is one of the pest species affecting Solanaceae worldwide. It can cause up to 80% of losses in potato open air crops as well as damage up to 100% of tubers during storage. Blattisocius (= Typhlodromus) mali (Acari: Blattisociidae), a predatory mite, was studied as a potential biological control agent of PTM. A prey acceptance bioassay

Potato is one the of world’s most important crops. It is grown primarily for human consumption but is also used to feed cattle and to produce alcohol and starch. In modern industry, potatoes are a major source of starch. Unpredictable growing conditions strongly influence the cultivation of starch potatoes. One of the best methods for dealing with unpredictable stresses, including those caused by climate

Green-sprouting potato seed tubers in light and elevated temperatures are vital for production in short-season climates. Using light-emitting diodes (LEDs) to inhibit sprout elongation during pre-sprouting may represent an energy-efficient alternative to traditional indoor light sources. Sprout growth inhibition and some photomorphogenic responses were therefore examined in potato cultivars exposed

RNA silencing is an important antiviral mechanism in plants. Small interfering RNAs (siRNA) or short hairpin RNAs (shRNA) are key stimulators for RNA silencing by acting as executors of viral restriction. Here, we have utilized RNAi technology to suppress potato virus X (PVX) in a transgenic potato cultivar. A stable shRNA of 107 bp directed against a conserved region in the coat protein (CP) gene

Potato (Solanum tuberosum L.) is one of the most important food crops worldwide but its cultivation is affected by numerous challenges including pests, diseases and high fertiliser requirements which have associated environmental problems. The exploitation of plant rhizospheres and their associated rhizobacterial interactions has gathered momentum worldwide in search of environmentally-friendly approaches

The term ‘quality’ is a complex parameter in the field of potato production, and the desired quality traits depend on the intended use. Important internal quality traits for potatoes are tuber flesh discolouration, dry matter, and starch content. External quality traits include tuber size and shape as well as resistance against mechanical stress during and after harvest. These quality traits are closely

As part of a successful agronomic strategy, adequate nutrient management of the potato crop is essential throughout the whole growth period. In this review, the importance of balanced fertilisation for potato yield formation and yield security is addressed by taking advantage of the results of field trials and existing literature. The most important roles of the macronutrients nitrogen, phosphorous

The irrigation method of partial root-zone drying (PRD) is based on drought stimulation without real water stress in order to induce xerophytophysiological signalling and regulations. In the present study, a series of measurements with potato (Solanum tuberosum L.) crops were conducted to understand the mechanisms underlying PRD. The results showed that PRD-induced osmotic adjustment shown by lower

Marker-assisted selection (MAS) is becoming increasingly common in commercial potato breeding programmes and can provide information to breeders on potential resistance to diseases and pests early in the breeding cycle when phenotypic screens are impractical. In recent years, a wealth of information on molecular markers for genes involved in resistance to biotic stresses of potato has been revealed

Photosynthetic properties and tuber yield were compared in seven tetraploid potato (Solanum tuberosum L.) clones (‘13-VIII-10’, ‘13-VIII-27’, ‘13-VIII-45’, ‘13-VIII-49’, ‘13-VIII-50’, ‘13-VIII-60’, ‘TG-97-403’) and three cultivars (‘Jelly’, ‘Satina’, ‘Tajfun’) at four localities in Poland under either integrated (Młochów, Boguchwała) or organic (Radzików, Chwałowice) fertilisation conditions applying

Phthorimaea operculella occurs in almost all potato-producing states in India and is considered to be a major potato pest in several states. The larva attacks all vegetative parts of the potato, and most economic damage occurs to potato tubers both before harvest in the field and during storage. The tuber damage in storage has been stated to range from 1 to 72.5% in the endemic states. In Karnataka

A squash print reverse transcription loop-mediated isothermal amplification amplification (SP-RT-LAMP) assay was developed for detection of Potato leafroll virus (PLRV) in a single aphid. Healthy aphids were given an acquisition feeding on potato plants infected with PLRV, and the acquired aphids were used for RNA isolation. The RT-LAMP assay was carried out using LAMP primers targeting the coat protein
