The possibility of a light scalar in the framework of two-Higgs-doublet models is studied. The range of masses 100 MeV < mh0 < 2mπ is already excluded by present experiment bounds on the transition η → π0h0 in the model where the neutral component of one doublet couples to fermions with weak isospin T3 = −12 and the neutral component of the second doublet to fermions with T3 = +12. These bounds also constrain tightly the structure of the Yukawa couplings in two-Higgs-doublet models.
