Abstract

Four mulberry silkworm races viz., Pure Mysore, Nistari, NB4D2 & CSR2 and two hybrid (Pure Mysore × CSR2 and Nistari × NB4D2 ) silkworms were selected for the present study. The specific activity of amylase in the haemolymph as well as midgut tissue was estimated. The qualitative analysis of amylase was carried out by Native-PAGE. The commercial characters viz., fecundity, larval weight, larval duration, cocoon weight, shell weight, shell ratio, filament length, denier and renditta were selected. The results of quantitative analysis were subjected for statistical analysis against selected commercial characters to know the level and kind of correlation between them. The results of statistical analysis clearly showed that haemolymph amylase has highly positive correlation with selected commercial characters except larval duration. In contrast, the midgut amylase indicated highly positive correlation with larval duration only. The zymograms of amylase also exhibited variation among the selected silkworm varieties.
