Hatchability, Disease Resistance and Quality of the Produced Cocoons among Five Selected Silkworm Races in Sericulture Development Division, Khopasi

Abstract

The fundamental aim of silkworm rearing is to get robust and sturdy silkworm larvae for easy rearing and production of best cocoons in quality and quantity for a high yielding cocoon crop. This study entitled “Hatchability, disease resistance and quality of the produced cocoons among five selected silkworm races in sericulture development division, Khopasi” was carried out in five races namely K1, K2, K3, STD1 and STD2 in Sericulture Development Division (SDD), Khopasi and include two treatments with 200 eggs of each races during the spring season of the year 2014. On the basis of Microsoft Excel 2010 analysis hatchability was found to be maximum in K1 race and minimum in STD2. Disease resistant race was identified as that of STD2 race as this race was least attacked by the disease. Finally K2 was recommended as best quality of cocoon among fiveraces on the basis of shell ratio calculation was found to be maximum.
