Abstract: Rana perezi from Portugal and southern France and two forms from Sicily (Italian hybrid and non-hybrid) were crossed with R. lessonae, R. ridibunda and R. esculenta from Poland. Crosses of 30 pairs belonged to 12 types. Most of zygotes from all crosses survive through nerula stages. Progeny of nine types of crosses completed metamorphosis and produced vigorous froglets; three crosses involving Italian hybryds had very little success. All progeny of Italian hybrid parents died shortly after completion embryonal development, and those with R. prezi and R. esculenta perished as tadpoles or during metamorphoses or shortly thereafter. The Italian hybrid lives and reproductively depends on the Italian non-hybrid, it passes only ridibunda-like genomes to gametes (hybridogenesis), all progeny fathered by Italian hybryds were females.
