Abstract
In this paper, we consider the quadratic perturbations of the one parameter family of reversible quadratic system that write in the complex form as $$\dot z = - iz(1 + a\bar z)$$ being a≠0 a complex number. We prove that the exact upper bound of the number of limit cycles produced by the period annulus system is two.
