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.
