Many factors contribute for the success of sericulture, among them silkworm seed plays a vital role because being a cash crop the vitality and disease freeness of the silkworm seed is of utmost importance. Production of silkworm seed is not only free from diseases but having high heterosis. The present study on grainage performance during autumn season showed that the grainage operation was carried out successfully at SSPC, Udhampur as the parameters studied depicted better eggs recovery in both the hybrids prepared i.e., 55.48g/kg in FC1 and 58.51g/kg in FC2 double hybrid. Further, the cocoons dfls ratio over actual number of cocoons was found 3.52:1 in FC1 and 3.02:1 in FC2.
