Analysis of correlation between commercial characters of Silkworm Bombyx Mori L.

Sixpure silkworm breedsviz., Pure Mysore, Nistari, C.nichi, NB4D2, KA & CSR2and threehybrid (Pure MysorexCSR2, NistarixNB4D2and KA x NB4D2) silkworms were used for the present study. The silkworm rearing was conducted during pre monsoon, monsoon and post monsoon seasons to get the mean values of selected commercial characters. The mean values of commercial characters viz., fecundity,larvalweight, larval duration, cocoon weight, shell weight, shell ratio, filament length, denier and renditta were subjected to regression analysis with each other individually to know the level of correlation coefficientbetween them. Of the 36 analysis,21 traits clearly showed the positive correlation
