“…Potato has a plethora of secondary metabolites that can have beneficial impact on the human health. Recently, serious changes were made in potato breeding program in Russia caused by new consumer requirements related to improve the quality of nutrition, to reduce the calorie content of food, to increase the content of high-grade protein, vitamins and antioxidants [2,3]. An integral part of a healthy diet for the population is a sufficient amount of antioxidants.…”

Fourteen Russian potato cultivars (cvs.) grown for three years in field plots of VIR (Northwestern region of the Russian Federation) were evaluated for productivity and a number of biochemical parameters of tubers. The 12 parameters that have been evaluated in tubers annually one month after harvesting and after cold storage (at 2 - 4°C) include the content of dry matter, starch, protein, ascorbic acid, carotenoids and β-carotene, anthocyanins, total sugars and monosaccharides (reducing sugars), phenolic compounds, as well as total acidity, and antioxidant activity. The cultivars differed significantly in productivity and biochemical composition of tubers. Dry matter content ranged from 16.40% in cv. ʻKumachʼ to 27.28% in ʻNayadaʼ, starch content ranged from 8.96 % in cvs. ʻFioletovyjʼ, ʻKumachʼ to 20.08% in ‘Sokur’, the total sugar content reached 2.46% in cv. ʻSiverskij’ whereas ‘Sokur’ has the smallest content of reducing sugars in post-harvest tubers. Protein content ranged from 1.02% to 2.77% with the highest accumulation in cv. ʻSokurʼ. Content of ascorbic acid (vitamin C) ranged from 6.3 mg/100 g FW in ʻKrasa Meŝeryʼ to 26.6 mg/100 g FW in cv. ʻKrasavchikʼ. Carotenoids content ranged from 0.157 mg/100 g FW in cv. ‘Nayada’ to 0.645 mg/100 g FW in cv. ʻGrandʼ. Content of anthocyanins in potato ranged from 1.04 mg/100g FW (not colored tubers of cv. ʻKrasa Meŝeryʼ) to 283.04 mg/100g FW (colored tubers of cv. ʻFioletovyiʼ). The nutritional value of tubers (content of dry matter, sugars, starch and protein) was determined to a greater extent (38-49%) by varietal characteristics, rather than by meteorological conditions in vegetation period. The content of vitamin C, carotenoids, protein and anthocyanins varied depending on the year. The highest content of dry matter, starch and carotenoids was noted in tubers harvested in 2019, marked by low temperatures and precipitation deficit in growing season. The conditions of 2020 with low temperatures and excess precipitation were the most favorable for anthocyanin’s accumulation in potato tubers while not for other biochemical parameters. Of the cultivars, ʻSokurʼ had the highest content of dry matter, protein and starch. Cv. ʻFioletovyiʼ had small starch content and high level of anthocyanins. Cv. ʻPlamyaʼ can be recommended for potato products manufacturing due to dry matter content above 20% and reducing sugars content 0.24%..

Fourteen Russian potato cultivars (cvs.) grown for three years in the field plots of VIR (North-Western region of the Russian Federation) were evaluated annually for productivity and 12 biochemical parameters of tubers one month after harvesting and after cold storage (at 2–4 °C). The aim of this study was to quantify the level of biochemical components in tubers and to determine the influence of the environment on their content. The results indicated a substantial variation in different nutrients in potatoes during cultivation for three consecutive years. The nutritional value of tubers (the content of dry matter, sugars, starch and protein) was determined to a greater extent (38–49%) by varietal characteristics, rather than by meteorological conditions in the vegetation period. The content of vitamin C, carotenoids, protein and anthocyanins varied depending on the year. Of the cultivars, ‘Kumach’ has the highest productivity, but the nutritional value of tubers is lower than that of standard ‘Nayada’. Cv. ‘Fioletovyi’ is suitable for consumption as part of a low-calorie diet because of a low amount of starch (11.8–12.7%) and a higher anthocyanins content (102.0–103.9 mg/100 g). Cv. ‘Sokur’ is distinguished by its high nutrition because of its high content of dry matter (24.3%) and protein (more than 2.0%). Cv. ‘Plamya’ is remarkable for the lowest content of reducing sugars (0.24–0.47%) in tubers during the post-harvest and post-storage analysis.

“…The high nutritional value of potato and the fact that the unit of surface produces significantly more protein than in the cultivation of other plants makes it a plant that should be included in the global strategy to combat hunger [10]. According to the FAO [11], with the growing world population, there must be an almost 50% increase in agricultural production by 2050.…”

Health Parameters of Potato Tubers under the Influence of Soil Applied Bio-Preparations and Bio-Stimulants

Increasing consumption of processed potatoes and consumer preference for buying potatoes washed and packed in transparent packages are a reason for increasing quality standards for potatoes. Processing and trade require potato tubers with smooth skin and without signs of disease, such as common scab, black scurf, and silver scurf. It is necessary to introduce protective measures to reduce the growth of pathogens causing these diseases and, at the same time, are safe for the environment and the consumer. To meet these requirements, the effects of application to soil and treatment of seed potatoes in the following solutions were examined: biological control agents (BCAs): Pythium oligandrum (BCAPo), Bacillus subtillis str. QST 713 (BCABs); microbial soil additives (MSADs): Efficient microorganisms (EM), UGMax soil conditioner, Biogen Rewital (BR); plant growth promoter (PGP): Ecklonia maxima (PGPEm) for the infection of the tubers by Streptomyces scabies (S.s), Rhizoctonia solani (R.s) Helminthosporium solani (H.s) and potato yield. Average Disease Severity Index (DSI) for common scab (S.s) 62.0%, black scurf (R.s) 57.88%, and silver scurf (H.s) 54.24%, obtained from three growing seasons, indicate their significant economic importance. The bio-preparations used significantly reduced their intensity. The effectiveness of protection for individual pathogens varied and was highly dependent on hydrothermal conditions. The analyzed preparations showed E between 8.0% and 50.8% against S.s. However, a stronger effectiveness was found in relation to H.s (12.9–56.6%) and R.s (19.5–69.2%). In years with water deficit, PGPEm and MSADs are more effective than BCAs in protecting potato tubers from skin diseases and contribute to higher yield increases. There was a significant negative correlation between the total DSI and the potato tuber yield.
