Аннотация

The article presents the results of research on selection and breeding selection aimed at improving the biological indicators of sex-marked silkworm breeds. The improvement of biological indicators of silkworm breeds marked by gender with the color of green is achieved by carrying out selection and breeding selection, which leads to an increase in the viability of caterpillars and silkworm cocoons. The results of the 3-year study showed that breeding work aimed at improving biological indicators marked on the floor by the stage of the silkworm eggs of species C-5 and C-14 allowed us to increase the viability of caterpillars breed-5 90,0% breed C-14 to 90.9% and silkiness of cocoons breed-5 to 20.3%, species C-14 to 23.7%. KEYWORDS: Silkworm, gender marking, breeds, selection, caterpillar viability, cocoon silkworm, green color.
