In this paper we use the Poincare bifurcation theory to prove that there may be just one double limit cycle or just two single limit cycles jumping out of the periodic cycle region in a quadratic system, and that there may be just one double limit cycle or just two single limit cycles jumping from an infinite separatrix cycle with only one infinite critical point in a quadratic system. And we give respective specific examples for them.
