Actinidia arguta and Actinidia purpurea and their hybrid cultivars are species which bear valuable fruits due to their content of valuable bioactive substances and good sensory qualities. This paper presents the yield results from the cultivars’ initial 10 years (2000–2009) as well as the morphology and chemical composition of the fruits of some Ukrainian hybrid cultivars of Actinidia arguta and Actinidia purpurea: ‘Figurnaja’, ‘Kijewskaja Gibrydnaja’, ‘Kijewskaja Krupnopłodnaja’, Actinidia purpurea: ‘Purpurowaja Sadowaja’ and Actinidia arguta: ‘Sientiabrskaja’. In 2007, the flowers of the tested cultivars were damaged by late spring frost. The lowest yield and the smallest weight, as well as the low stability of morphological features of fruits of the ‘Sientiabrskaja’ cultivar, indicate its low utility as a commercial crop in north-eastern Poland. However, chemical analyses found high levels of phenolic compounds and vitamin C in the fruit of the cultivar. An analysis of the yield and fruit quality of the other tested cultivars indicated their suitability for cultivation under the climatic conditions of the 6A USDA zone.
