In Romania, the sweet potato is recently cultivated, especially in the South-West region. This region has a temperate continental climate that is characterized by the lack of water in the soil and atmosphere and by a diversity of soil types, very important factors for the cultivation of this species. The lack of information about the real effects of the environmental factors on the nutritional quality and the production of sweet potatoes grown in this area led to this study. Therefore, the present paper aims to evaluate the nutraceutical content of 5 sweet potato genotypes, such as: TSS (total soluble substance), total carotene, reducing sugars, vitamin C, phenolic compounds, flavonoid content and antioxidant activity (determined by DPPH and ABTS) grown in the specific climatic conditions of this region. There was found a differentiated nutritional quality depending on the genotype, so that genotype 5 was rich in carotene (59.29 μg/g FW) and vitamin C (36.56 mg/100 g FW). The data presented in this study also refer to the total number of roots/plant, the average weight/root, the total production/ha, the biomass production/ha and the production index. Regarding these elements, genotype 3 recorded a biomass production of 39.5 t/ha and a total tuber production of 50.3 t/ha. The results presented in this study indicate that the production of this species is climate dependent, which influences important metabolites in tubercles, that plays an essential role in organoleptic properties.

The aim of the study was to assess the possible antioxidant and antiproliferative effects of various sweet potato extracts (Ipomoea batatas [L.] Lam) in terms of their suitability for food processing. Antioxidant activity of water infusions from the leaves of 5 sweet potato varieties (Carmen Rubin, Cananua, Georgia Jet, Satsumo Imo, White Triumph) obtained from field cultivation in Felin (51°13'N, 22°37'E) was determined. The field experiment was carried out using the randomized blocks method, in triplicate, in accordance with the principles of good agricultural practice. The leaves were collected at phase 68 according to the BBCH scale. After harvesting, the leaves were dried to constant weight. After drying, the leaves were saturated with water at 80 ° C and 100 ° C for 3, 6 and 9 minutes. The total content of phenolic compounds was determined by the method of Ghasemzadeh et al. Antioxidant activity of sweet potato leaf infusions was determined by DPPH radical spectrophotometry. The time to prepare the infusions significantly differentiated the TP content. Infusions evaluated after 3 minutes were the most favorable in this respect. The antioxidant activity of the tested infusions obtained from sweet potato leaves ranged from 33% to 59%, depending on the variety, and 34-43%, depending on the time the infusion was prepared. Leaf infusions prepared at 100°C had a higher antioxidant activity than infusions made at 80°C. The highest antioxidant activity was revealed by infusions from White Triumph cultivar leaves, lowest -from Cananua cultivar leaves.

Purpose. To justify the use of the Lewis phenotypic stability factor (SF) to determine the stability of the manifestation of quantitative and economic value characteristics of national varieties of sweet potato (Ipomoea batatas L.). Methods. Field research on the comprehensive assessment of new sweet potato varieties was carried out in 2021–2022 at the Institute of Vegetable and Melon of the NAAS (Kharkiv Region). Phenological observations and biometric measurements of plants were carried out, as well as recording of meteorological data during the growing season, in particular during interphase periods of the culture. The stability of the studied traits was determined by finding the limit values of their manifestation (Xmax and Xmin) and further calculating the Levis phenotypic stability factor (SF). Results. The use of the Levis phenotypic stability factor (SF) made it possible to determine the stability of the manifestation of morphological features of sweet potato varieties (I. batatas), in particular, the quantitative characteristics of tubers: their number under the bush for the variety ‘Admiral’ is 5.3 pcs., for ‘Slobozhanskyi rubin’ – 3.7 pcs.; the average weight of the tuber is 254 and 283 g, respectively. The trait “sweet potato tuber shape index” ensured stability with a coefficient of 0.98 (‘Admiral’) and 1.03 (‘Slobozhanskyi rubin’). The stability of the manifestation of morphological features of sweet potato tubers was established for the varieties ‘Admiral’ and ‘Slobozhanskyi rubin’, which are common in Ukraine. They represent two maturity groups, and therefore differ in the duration of the tuber formation period. Thus, the early-ripening ‘Admiral’ has a vegetation period of 100–110 days; medium-ripening ‘Slobozhanskyi rubin’ – 110–120 days. Conclusions. The quantitative trait of sweet potato tubers of the ‘Admiral’ variety was more stable in terms of width; ‘Slobozhanskyi rubin’ variety – in terms length. Tuber length values varied within cultivars. The shape index of sweet potato tubers as an identification feature of varieties turned out to be variably unstable; the calculated Lewis phenotypic stability factor was lower than unity for both studied varieties.
