The concentrations of the bioactive compounds in potato tubers are determined by both genetic potential and environmental factors. The purpose of the experiment was to determine the influence of organic and integrated production on the expression of the genetic potential with respect to the antioxidant properties of potato tubers and to evaluate its stability under different environmental conditions. This phenotyping was performed on seven new breeding lines (tetraploid clones) and three modern cultivars: Jelly, Satina and Tajfun. The results indicated that production system and location significantly influenced the antioxidant capacity measured by FRAP method. Organic farming and the location Chwałowice were characterized by higher values. Furthermore, anitioxidative capacity measured by FRAP method was correlated with chlorogenic acid content (r = 0.590**) and glutathione fractions, especially with the reduced form (GSH, r = 0.692**). Multidimensional comparative analysis (MCA) proved a better development of antioxidant properties of potato tubers in the organic cultivation system when compared with the integrated. Especially favorable were growing conditions at Boguchwała (organic) and worst at Młochów (integrated). From all investigated varieties, the best antioxidant properties were found in 'Satina' and 'Jelly'. Clones TG-97-403 and 13-VIII-45 developed the weakest health promoting traits.
块茎中生物活性化合物的浓度取决于遗传潜力和环境因素。本实验旨在确定有机和综合生产对马铃薯块茎抗氧化特性的遗传潜力表达的影响，并评估其在不同环境条件下的稳定性。该表型分析在七个新的育成系（四倍体克隆）和三个现代品种：Jelly、Satina 和 Tajfun 上进行。结果表明，生产系统和地点显著影响了 FRAP 法测定的抗氧化能力。有机农业和 Chwałowice 地区的特征是具有更高的价值。此外，FRAP 法测定的抗氧化能力与绿原酸含量（r = 0.590**）和谷胱甘肽分数，特别是还原形式（GSH，r = 0.692**）相关。多维比较分析（MCA）证明，与综合生产相比，有机生产系统中马铃薯块茎抗氧化特性的发展更好。在 Boguchwała（有机）的种植条件尤其有利，而在 Młochów（综合）的种植条件最差。在所研究的所有品种中，'Satina'和'Jelly'发现具有最好的抗氧化特性。TG-97-403 和 13-VIII-45 两个克隆系则表现出最弱的促进健康的特性。
