Abstract
A strong violation of the Quark Line Rule is observed if we allow the pion nucleon σ term to attain the present experimental value. This in turn indicates the possibility of a large strangeness content in the proton. In this work we have shown that the value of the σ term is seen to be raised from what is expected from the GMOR scheme of chiral symmetry breaking through a sum rule which shows that the ratio of the meson wave function renormalization constants Z K 1 2 / Z π 1 2 may deviate considerably from unity by using the recent QCD estimate on the quark vacuum condensate ratio < ss > O /< uu > O
