Evaluation of different larval stages of silkworm hybrids in Jammu division of Jammu and Kashmir

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.
