چکیده انگلیسی

Efficiency of natural silk thread production is conditioned completely by high productivity of mulberry silkworm breeds and hybrids and by biotechnological characteristics of cocoon. Silk capacity is one of the most significant indices of breed productivity. Nutrition of Georgian breeds and hybrids of mulberry silkworm of Mziuri and Digmuri groups was performed in the Georgian Agrarian University, in the laboratory of sericulture, in spring seasons of 2012–2014. In the process of grain incubation and silkworm feeding the first day selection methods were used. Silk capacity, worm viability and cocoon yield were considered as the main signs for selection. Emphasis was made on the increase of silk capacity in further generations. At the nutrition of Mziuri and Dighmuri group mulberry silkworm breeds in 2012–2014 years, economic indices such as silk capacity and cocoon yield per gram worm have increased. At the nutrition of Mziuri and Doghmuri group breeds in similar conditions it became vivid that Dighmuri breeds are more resistant to diseases. To elevate viability and biotechnological characteristics it is necessary to carry out significant selection measures, application of blood refreshing method to overcome inbreed depression.
