Abstract
Selection of the inbred type of silkworm for vitality allows removal of inbreeding depression in various breeds of inbreeding. Inbreeding type hybridization with fifth fine silk bred improves technological features of cocoon thread. The research was carried out in the laboratory of genetics and breeding of the silkworm of the Research Institute of Sericulture in the period from 2009 to 2011. For the creation of hybrids, the previously inbred lines and lines with a thin cocoon thread of rocks Japanese 66, Chinese 108 were used. Analysis of the features of inbred lines and their hybrids with the original rocks showed that all inbred lines show heterosis. Based on the data obtained, conclusions were drawn that made it possible to use the results of the work in silkworm breeding, and also determined further ways of research.
