Abstract
The discuss toy models where supersymmetry is broken due to a nonvanishing time-varying vacuum expectation value of the inflaton field during preheati ng. We discuss the production of an inflatino, the superpartner of the infl aton, due to vacuum fluctuations and then we argue that they do not survive until nucleosynthesis and decay along with the inflaton to produce a therm al bath after preheating. Thus the only relevant remnant which has any sign ificance to be constrained from nucleosynthesis is the helicity +/-3/2 grav itinos.
