We have measured the magnetoresistance and the de Haas-van Alphen effect of YRu2Si2. The Fermi surface and cyclotron mass of YRu2Si2 are compared to those of LaRu2Si2 and LaRu2Ge2. Main hole Fermi surfaces of the three compounds are similar and ellipsoidal in shape, which occupy about half of the Brillouin zone. The small hole Fermi surface with a shape of rugby ball is one in number for YRu2Si2, while three for LaRu2Si2 and LaRu2Ge2. A cylindrical Fermi surface and a multiply-connected Fermi surface exist for YRu2Si2, while there exists a doughnut like electron Fermi surface for LaRu2Si2 and LaRu2Ge2. The cyclotron masses of YRu2Si2 are about 50% and 10% larger than those of LaRu2Si2 and LaRu2Ge2, respectively.
