Potato Research

The European Association for Potato Research (EAPR) publishes a journal, Potato Research, which includes original scientific contributions on both fundamental and applied research on potatoes, review articles and topics of general interest. It also contains Association news and reports on section meetings (including abstracts of papers presented).
A volume of the Journal (usually approximately 450 pages), consists of four issues, published in the same year. Submission of manuscripts is exclusively online via a web-based electronic submission and tracking system available at https://www.editorialmanager.com/potr

Contribution and Stability of Yield Components of Diploid Hybrid Potato
22nd January, 2020
Abstract

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 diploid hybrids showed a yield comparable with the lower yielding tetraploid cultivars. Yields of hybrids and commercial tetraploid cultivars were broken down into different yield components and the interactions with growing conditions were quantified. The stability of yield and other relevant traits in different growing conditions was similar between hybrids and commercial cultivars. The contribution of the different yield components to total yield over different environments was compared between diploid hybrids and tetraploid cultivars. In diploid hybrids as well as tetraploid cultivars, more tubers per stem resulted in the highest yield gain, while an increase in tuber size resulted in a relatively smaller increase of total yield.

Biotechnological Methods of Management and Utilization of Potato Industry Waste—a Review
14th January, 2020
Abstract

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 following wastes are formed: potato wastewater, potato pulp, peel, distillery wastewater and pulp. These wastes can then be managed as components of microbial media in the biotechnological production of cellular biomass of yeasts, microbial polysaccharides, protein and lipids, carotenoids, enzymes and organic acids. On the one hand, this allows for the reduction of costs of production of food components through microbial synthesis, and on the other, it enables the environmental management of industrial waste. The present article discusses the most important studies concerning the biotechnological management of wastes of the potato industry.

Recent Updates on Healthy Phytoconstituents in Potato: a Nutritional Depository
8th January, 2020
Abstract

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, vitamins as well as minerals. In India, more than 75% of the potato production is confined to Indo-Gangetic plains due to thermo-sensitivity of the crop. Several reports are available in recent years to develop new cultivars with improved nutritional value as well as nutrient evaluation of existing cultivars. Current status of research on potato phytonutrients particularly antioxidants, minerals and vitamins in relation to human health as well as research carried out on enhancement of these phytonutrients through genetic manipulations has been compiled in this review article.

Effects of Anti-browning Treatments on the Polyphenol Oxidase and Antioxidant Activity of Fresh-Cut Potatoes by Using Response Surface Methodology
4th January, 2020
Abstract

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 of freshly cut potatoes stored in the refrigerator for later preparation of a meal. For this reason, studies to minimise negative changes in fresh-cut potatoes during cold storage are important. The quality of freshly cut potatoes immersed in ascorbic acid and collagen hydrolysate solutions was investigated to obtain maximum storage time by using response surface methodology. Colour, polyphenol oxidase (PPO) activity and antioxidant activity were monitored to estimate quantitative changes of the product over refrigerated storage. The binary effects of collagen hydrolysate and ascorbic acid slowed polyphenol oxidase activity and prevented browning of potato surface colour. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging effect increased with the use of collagen hydrolysate and ascorbic acid at the beginning of storage and decreased at the end of storage. ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)) radical cation scavenging effect increased with the use of collagen and ascorbic acid during storage. The treatment of collagen hydrolysate and ascorbic acid in fresh-cut potatoes was successful in slowing PPO activity at the end of storage. Optimal conditions slowing down PPO activity at the end of storage are collagen 0.22% and ascorbic acid 0.30%.

Yield and quality characteristics of popular processing potato ( Solanum tuberosum L.) cultivars in two contrasting soil types under grower management in Hokkaido, Japan
4th January, 2020
Abstract

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 to guide formulation of better management practices to increase yields. This study was conducted in Hokkaido, Japan, to evaluate the performance of four popular processing potato cultivars under variable soil environment and grower management conditions. The study was conducted by obtaining soil and tuber samples from 90 and 80 fields in Tokachi and Kamikawa districts, respectively, in two growing seasons. These two districts represent very contrasting soil types. Kamikawa has pyroclastic flow deposit soils classified as Inceptisols whereas Tokachi has volcanic ash soils known as Andisols. Paired samples of soil and tubers were evaluated at each of these sites. The results indicated the following: (1) Significant cultivar effect on various measured parameters including tuber yield, tuber number, mean tuber weight and specific gravity. (2) Toyoshiro cultivar performed better than other cultivars in both Tokachi and Kamikawa districts. (3) Yields varied from 21.9 to 68.2 t ha−1 indicating that with good management, there is a considerable yield-improvement opportunity. (4) Interestingly, stem number was significantly affected by soil type. The stem numbers were generally greater in the Kamikawa District suggesting high available N and P and lower available Ca in this region, possibly in conjunction with other unmeasured factors, contributed to greater stem numbers.
