The reproductive efficiency in the grandparent stock and the parent stock of geese was monitored in the thesis. In terms of the grandparent stock, there were found out better values in year 2012 than in year 2013. In 2012, there was a better egg fertilization of 4.61 % (the average was 49.65 %) and hatchability of the put eggs better of 3.83 % (the average was 39.01 %). The hatchability of the fertilized eggs was almost the same in both years. It has the same value of 78.63 %. Best results were proved in strains 1, 3 and 4. Worst values were proved in the strain number 41. The chosen indicators of geese of four ponds were monitored in the parent stock. The average fertilization of eggs was 58.26%; significantly higher value was proved in case of the Jakulský pond (72.34%). The average hatchability of the put eggs reached 46.46%; the highest value was also proved on the Jakulský pond (56.22%). The other ponds have balanced results. The hatchability of the fertilized eggs reached the average value of 79.10%, the highest value was proved on the Lomský pond (84.45%); the second place is represented by the Velebil pond (79.42%). The geese bred on the Lomský pond had eggs with the lowest fertilization, but with the highest percent of hatchability of the fertilized eggs. In case of geese bred on the Velebil pond, there was an increase of the monitored indicators in year 2013 than in 2012. In contrast, the Byňovský pond, the Jakulský pond and the Lomský pond showed an increase of the monitored indicators in 2012. There was a smaller difference of egg fertilization in geese of the Jakulský and the Lomský pond. There was a smaller difference of hatchability indicators of either put or fertilized eggs in geese bred on the Byňovský and the Jakulský pond.
