Data of prolificacy traits of the Hungarian Upgraded gander x Grey Landes layer and Grey Landes gander x Hungarian Upgraded layer stocks were tested in the period of 1989-1992. The birds were performed in the second laying cycles at Babat Goose Breeding Research Station of the University of Agricultural Sciences, Godollo. X2-test was applied for comparison of egg production, fertility and day-old gosling production curves by breeds and years. Significant differences were found in the curves of egg production of Hungarian Upgraded x Grey Landes between years of 1989-1990 and 1989-1992. (P0.05), and in Grey Landes x Hungarian Upgraded stock between years of 1989-1991 (P0.01) and 1989-1992 (P0.05). The curves of fertility of Hungarian Upgraded x Grey Landes showed significant difference only between 1989-1992 years and of Grey Landes x Hungarian Upgraded between 1989-1991 and 1989-1992 years (P0.001). The production of goslings showed significant differences between years only in the Hungarian Upgraded x Grey Landes stock, between 1989-1990 and 1989-1992 years (P0.05). There were no significant differences between the two stocks in their production of eggs, day-old goslings or fertility of eggs
