abstract
Data on six commercial economic characters was recorded during the rearing. The recorded data was computed and analyzed by analysis of variance and heterotic crosses were screened by using a multiple trait index method. The data revealed that the larval duration depicted non-significant results; however U6×ND3 and CC1×U1 recorded shorter larval life of 23.17 days. Significantly higher weight gain and growth rate were recorded by the hybrid U6×ND3 whereas maximum larval weight was achieved by the hybrid JD6×U6. It can be concluded that hybrid U6×ND3 can be utilized for field rearing after validating the results through multi location traits at the farmer’s level.
