... The study attempts to analyze the extent of market integration and causality relationship in major potato markets of West Bengal state. Price and arrival data from Jan, 2006 to Aug, 2021 of six major potato producing districts namely Burdwan, Coochbehar, Jalpaiguri, Hooghly, Nadia and Bankura are selected. In analysis, seasonality indices reveals existence of significant variation in crop. Instabi ...
... Field trials to evaluate the performance of new varieties are an essential component of potato breeding. Besides the genetic differences, environmental factors can lead to variation in a trial. In variety trials, the observed differences amongst varieties should reflect genetic differences, without a large impact of the random or systematic variation in the field. One way to reduce within-field va ...

Abstract:
... The effectiveness of static magnetic fields (SMFs) in improving food freezing is a topic that, nowadays, raises substantial controversy among the scientific community. To shed light on this matter, new freezing experiments, under well controlled conditions, were performed in potato samples subjected or not to SMFs of either 40–55 mT or 150–200 mT, that is, approximately 1000 and 5000 times greater ...

Abstract:
... Presence of thermal processing contaminant in foods has long been taking attention due to their probable toxic effects. Roasting coffee beans at very high temperatures creates major changes in the chemical composition and in the physical properties. Coffee beverages are important contributor to the exposure to acrylamide following potato and cereal products. This review describes the changes durin ...

Abstract:
... Late blight remains the most devastating disease in potato cultivation. The best protection against this disease could be achieved by durably resistant cultivars, but these do not exist at present. To advance resistance breeding, the search for resistant wild potato species and the characterization of their resistance is important. There have recently been a number of new developments in this area ...

HighlightsPotatoes of different mass had significantly different moving times and trajectories during unloading.Moving time and trajectory length increased with the increase in mass level of potatoes at different initial speeds.The belt-fed potato sorter developed by investigating potato moving trajectories had high accuracy and low damage.Abstract. Belt conveyors are one of the main transport met ...
... Ditylenchus destructor is a plant-parasitic nematode that seriously infests sweet potato crop in China. Thus, fast and accurate detection of D. destructor in soil and plant tissue samples is of great significance. In this study, a real-time recombinase polymerase amplification (RPA) assay was developed for the rapid and accurate detection of D. destructor in various samples. The RPA assay could be ...

Abstract:
... The technology of hybrid breeding in diploid potatoes creates opportunities to design novel and improved cultivation systems based on hybrid true potato seeds. A promising cultivation pathway to produce seed or ware tubers is by transplanting greenhouse-raised seedlings into the field. This study explored the effects of transplanting date and seedling age on tuber yield, using greenhouse-raised se ...

... The current study focused on the impact of climate change on tropical root and tuber crops of India over some of the major growing areas using the crop model, WOFOST. As part of this study, the impact of climate change on the yield of rice and potato is also carried out using the same crop model to understand the advantages of root and tuber crops over the yield variations of rice and potato. The ...
... The effect of high‐pressure cooking processing (HPCP) on the physicochemical structure and in vitro digestion of citric acid‐esterified starches made from different materials (water chestnut, sweet potato, potato, corn) was investigated. HPCP increased the swelling and solubility of sweet potato esterified starch (SPSC) and potato esterified starch (PSC) and decreased the swelling and solubility o ...

... Plots infested with Synchytrium endobioticum, the causal agent of potato wart disease, are scheduled, resulting in prohibition of potato cultivation of and cultivation of plants for planting. On account of robust resting spores that are present in infested soils, plots remain scheduled for 20 years. After this period, plots are intensively sampled and the presence of resting spores in soil is dete ...

Abstract:
... l-glycine and l-serine are the building blocks of proteins and exhibit various biological activities. This work found that l-glycine and l-serine show low scavenging capacity for methylglyoxal at moderate conditions (pH 7.0, 37 °C). However, they efficiently eliminate methylglyoxal and formaldehyde when the two aldehydes co-exist, via generation of imidazole salt, a compound formed by one molecule ...

Abstract:
... The productivity of potato in Colombia is below its potential due to continued agronomical malpractices that have resulted in a high prevalence of pathogens, particularly viruses. This work presents a pilot virus seed-indexing study using the tuber sprouting test (TST) with RT-qPCR. TST was performed in certified and uncertified seed-tuber lots of potato cultivars: Diacol Capiro and Criolla Colomb ...

Abstract:
... Although there are over 4000 potato cultivars in the world, only a few have been commercialized due to their marketability and shelf-life. Most noncommercialized cultivars are pigmented and found in remote regions of the world. White-fleshed potatoes are well known for their energy-enhancing complex carbohydrates; however, pigmented cultivars are potentially high in health-promoting polyphenolic c ...
