Actinidia arguta and Actinidia purpurea provide tasty and nutritionally valuable fruit that are edible directly or after processing, without peeling. The aim of the study was to determine the content of macro- and microelements in the fruit of three Ukrainian hybrid cultivars of Actinidia arguta × Actinidia purpurea: ‘Figurnaja,’ ‘Kijewskaja Gibrydnaja,’ ‘Kijewskaja Krupnopłodnaja,’ Actinidia arguta: ‘Sientiabrskaja,’ and Actinidia purpurea: ‘Purpurowaja Sadowaja’ during five years of cultivation (2006-11) in northeastern Poland. Determining the chemical composition of actinidia fruit yields was performed after wet mineralization. The results have shown that fruit of the ‘Sientiabrskaja’ cultivar of Actnidia arguta contained the highest concentrations of N, P, Ca, and Mg, as well as Cu and Mn. Fruit of the ‘Purpurowaja Sadowaja’ cultivar of Actinidia purpurea contained the highest concentrations of K and Zn. Fruit of hybrid cultivars ‘Figurnaja,’ ‘Kijewskaja Gibrydnaja’ and ‘Kijewskaja Krupnopłodnaja’ were found to contain the lowest concentrations of N, Ca, Mg, and Zn. Fruit of ‘Figurnaja’ and ‘Kijewskaja Gibrydnaja’ contained similar amounts of P, Ca, and Mg, but their Na content was different.
