Abstract
Quality silkworm seed play a vital role for production of better cocoon yield. Irrespective of fecundity. uniform number of eggs should be fixed for 100 dfls while assessing performance of silkworm breed or hybrid. Though the yield is directly proportional to fecundity. hatching percent. ERR percent and single cocoon weight, standard norms should be fixed for determination of cocoon yield/100dfis. The Saha Ready Reckoner described here may be helpful in direct assessment of cocoon yield at laboratory and field level easily.
