The present study of green frog hybrid populations of Ukraine, including analysis of allozyme variability and planimetric analysis of erythrocytes size has confirmed that the unique region in this area is the Severski Donets basin. The allopolyploid individuals there are met very frequently (5,7 % of all investigated frogs). In other areas of Ukraine only two polyploid hybrids have been recorded. Besides that, one frog was defined as triploid Rana ridibundus. According to our investigations, all triploid hybrids from the Severski Donets basin are identified as P. esculentus (=lessonae)– 2 ridibundus males.
