“…In agreement with our results other authors also found that the flesh of yellow coloured tubers accumulates higher quantities of carotenoids (Breithaupt andBamedi 2002, Andre et al 2007). On the other side, cream, blue and white flesh-coloured cultivars contained significantly lower levels (Valcarcel et al 2015). If the effect of violet and red colour of the flesh on the Hejtmánková et al (2013), who reported ranges from 1.3-5.6 mg TC/kg DM in eight cultivars with purple flesh and from 2.2-4.8 mg TC/kg DW in four red-fleshed cultivars; in agreement with our results they demonstrated dependence of TC content on genotype cultivars.…”

“…The concentration of carotenoids is affected by several factors such as genotype, agronomic factors, postharvest storage, cooking and processing conditions (Kotíková et al 2007, Ezekiel et al 2013, Hejtmánková et al 2013) and environmental factors (Valcarcel et al 2015). In recent years there has been a growing interest, especially among fans of a healthy diet, in cultivars with coloured flesh, which are an important source of anthocyanins, and thus popularity of these cultivars is spreading in the world fairly quickly (Lachman et al 2012, Hamouz et al 2014.…”

In this study, twelve cultivars of potato with different flesh colour (yellow, purple and red) were cultivated in 2012 and 2013 in two trial localities in the Czech Republic and evaluated for the main individual carotenoids. The content of total carotenoids (TC) in analysed cultivars ranged in 1.1-12.2 mg/kg in dry matter (DM) and was influenced by genotype cultivar, locality and year. Cv. Agria (yellow flesh) reached 1.8 to 11.8 times higher levels of TC compared with cultivars of coloured flesh. Locality and year of higher average temperatures during the growing season produced higher TC contents in tubers. Genotype significantly influenced the content and composition of individual carotenoids. As in cv. Agria, violaxanthin (41%) and lutein (55-78%) dominated in all cultivars with coloured flesh. The relative content of β-carotene in cv. Agria represented 2% of TC, in cultivars with coloured flesh 5-12% TC.Keywords: Solanum tuberosum; tuberous crop; xanthophyll; biological antioxidant; variety of potato; weather condition Potatoes are a good source of carotenoids, which are lipophilic compounds synthesized in plastids from isoprenoids (Brown et al. 2008, Ezekiel et al. 2013. The main potato carotenoids are xanthophylls, which are not precursors of vitamin A, but are components on the human retina and prevent cells from damage caused by UV-light. Carotenoids are also effective as biological antioxidants and therefore are probably a key factor in reducing the incidence of many diseases, including cardiovascular diseases, cancer, cataract and macular degeneration (Burgos et al. 2012). Lutein, zeaxanthin, violaxanthin and neoxanthin are the major carotenoids present in potatoes, while β-carotene is present only in trace amounts. The orange and yellow colour of the tuber flesh is mainly due to zeaxanthin and lutein, respectively. Potato cultivars with white flesh contain less carotenoids as compared to cultivars with yellow or orange flesh. Total carotenoids content was reported in the range of 50-350 µg/100 g of fresh matter (FM) and 800-2000 µg/100 g FM, respectively, in white-and yellow-fleshed potato cultivars (Brown et al. 2008).The concentration of carotenoids is affected by several factors such as genotype, agronomic factors, postharvest storage, cooking and processing conditions (Kotíková et al. 2007, Ezekiel et al. 2013, Hejtmánková et al. 2013) and environmental factors (Valcarcel et al. 2015). In recent years there has been a growing interest, especially among fans of a healthy diet, in cultivars with coloured flesh, which are an important source of anthocyanins, and thus popularity of these cultivars is spreading in the world fairly quickly (Lachman et al. 2012, Hamouz et al. 2014. However, data published on their carotenoid contents are absent. The aim of this study was to quantify the level of total and individual carotenoids and to determine the percentage of individual carotenoids in eleven 86 Vol. 62, 2016, No. 2: 86-91 Plant Soil Environ.

“…Higher levels of total carotenoids were found in the skin of tubers, with maxima values of 28 and 9 mg/kg dry weight (DW) in skin and flesh, respectively. Yellow-skinned or fleshed tetraploid cultivars also had higher contents than those with paler or white tissues, with no relationship found for other colours (Valcarel et al 2015). Carotenoid concentrations in some diploid potatoes were reported up to 22 times higher than in white-fleshed potatoes (Haynes et al 2011).…”

In this study, three cultivars and seven tetraploid potato clones were evaluated for two years in two cultivation systems (CS): without chemical protection against late blight development (NP) and with chemical protection (P). The objective of this study was to quantify the effect of chemical protection on the level of total carotenoids (TC) and individual carotenoids in potato tubers. The presented study showed that the content of TC in potato tubers is significantly affected by the CS and genotype. TC were higher in the system NP (mean 329.6 µg/100 g fresh weight [FW]) than in the system P (mean 206.2 µg/100 g FW). Although the development of late blight was observed only in the year 2019, a higher content of TC was observed in the system NP in both years. This dependence clearly show that CS without chemical protection favor carotenoids accumulation in potatotubers. In the case of lutein, the year had a significant impact on the concentration. The concentration of lutein in 2018 for the majority genotypes was higher (mean 72.1 µg/100 g FW), than in year 2019 (mean 37.3 µg/100 g FW), when late blight development wasobserved. The sharp decrease in lutein content in 2019 was probably caused by the development of late blight. A significant decrease of lutein content in potato tubers was observed in 2019 for all genotypes in system P and for five genotypes in system NP. It can be assumed that resistance mechanisms that occur during infection may have disturbed the accumulation of lutein in potato tubers.
