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

The present study evaluated the content of glycoalkaloids (α-chaconine and α-solanine) in the edible portion of six hybrid potato clones coming from the Italian potato breeding programme focused on resistance against the potato tuber moth (Phthorimaea operculella Zeller). To evaluate the influence of agro-climatic conditions on glycoalkaloid content, the potato clones were grown for two consecutive

In potato cultivation, the problem of controlling broadleaf weeds could be solved with the production of plants resistant to the broadleaf herbicide bentazone. Plant tissue culture technology and herbicide screening technology were used to select bentazone-resistant potato materials and to analyse the physiological and biochemical characteristics of their resistance. Potato microtubers were used as

Chemical agricultural inputs (e.g. pesticides and fertilizers) pollute the environment and undermine food safety. In fact, agriculture is in a direct relationship with the environment and farmers’ behaviours have extensive positive or negative impacts on it. Therefore, enhancing farmers’ behaviours to go towards organic farming methods represents a promising approach. The present study aimed to explore

This study assessed the feasibility of providing a regular supply of locally produced potatoes during landlocked winter months in Ladakh region. Potato tubers were stored (January–May) in semi-underground stores where conditions were between 0.2–13.6 °C and 87–96% relative humidity. Periodical sample analysis was carried out on sensory attributes and the physicochemical attributes firmness, sprouting

South Africa harbours many small-scale potato growers who produce for home consumption and local markets using variable levels of inputs (seed, nutrients, water). We assessed potato production practices, input resource use and use efficiencies, farm characteristics and yield gaps on smallholder potato farms in the KwaZulu Natal and Mpumalanga Provinces of South Africa through a survey and a crop model

Potato (Solanum tuberosum L.) being a vegetatively propagated crop is infected by a large number of viral diseases, most of which are transferred over generations through planting material (tubers), duly responsible for degeneration of seed stocks over the years. In the recent past, the most important geminivirus infecting potato has been Tomato Leaf Curl New Delhi Virus-Potato (ToLCNDV-Potato) or

An experiment was performed to study the impacts of elevated CO2 concentrations and climatic warming on potato growth during 2016. The changes in potato gas exchange parameters, yield and nutrient composition and the microelement concentrations in tubers were analysed. The results showed that potato growth was affected by warming and the elevated CO2 concentration. The net photosynthetic rate (Pn)

The present study investigated the diversity of culturable rhizobacteria associated with potato (S. tuberosum L.) in Tanzania and assessed their in vitro plant growth-promoting (PGP) activities to deduce their potential as biofertilizers. Potato rhizosphere soil and tuber samples (54 samples in total) were collected from 9 villages in three different agro-ecological regions in Tanzania. A total of

In Brazil, the potato cultivar Agata is used for fresh market, while the cultivar Markies is used for both fresh market and frying industry. However, these cultivars may respond differently to nitrogen (N) management. Thus, field experiments with these cultivars were conducted to evaluate marketable tuber yield and physico-chemical and nutritional quality of tubers in response to four different early

Samples of blighted potato leaves were collected from fields in six potato-growing districts of the Punjab Province of Pakistan in 2017–2018. A total of 149 isolates of Phytophthora infestans were obtained from six potato cultivars (Asterix, Barsenna, Burana, Caroda, Mazika, Sante). Of these isolates, 73% were A1 mating type, 23% were A2 mating type and 4% were self-fertile. Both mating types of P

The frequently changing climate has resulted in plants facing more biotic and abiotic stresses than ever before, leading to yield and quality losses. The global population is increasing at an alarming rate and feeding the world has become a huge challenge. Being a staple crop of many countries, potato can help to overcome this challenge. A comprehensive knowledge of physiology, biochemistry and molecular

Pectin methylesterase (PME) is a type of protein encoded by a multi-gene family and participates in seed germination, fruit ripening and stress response. To further study the function of the PME gene family in potato, this paper screened and identified potato PME gene family by bioinformatics methods, and analysed the structure, physicochemical properties, conserved domains and evolutionary relationships

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
