ZSSO coordinates and monitors the activities of Basic Seed Farms, Silkworm Seed Production Centres, Cold Storage Plant etc.. It also takes care of the rearing of authorised silkworm breeds at the BSFs and thereby the production of basic seed for further multiplication. Apart from this it also takes stock of the seed cocoon generation and production of commercial dfls by the Silkworm Seed Production Centre. The planning for production and disposal of the dfls is done well ahead of the season.
