We consider QCD based model of hadrons interaction in which gluons density in wave function of initial state is low in rapidity space and real hadrons are produced by decay of color field strings. Hadrons production processes in pp and p antip interactions differ on principle. There are three types of inelastic processes in p antip collision. The first type is production of secondary hadrons shower from decay of gluon string. The second type is shower produced from decay of two quark strings and the third one -- from decay of three quark strings. At the same time there are only two types of inelastic processes for pp collision, they are shower from gluon string and shower from two quark strings. Therefore multiplicity distributions and inclusive spectra of secondary hadrons are different in pp and p antip interactions, and this difference may be observed at energy sqrt(s)=900 GeV.
