Possibility of industrial use of silkworm breeds sex-tagged at the egg stage

Abstract

Sericulture throughout the world is based on the production of only first generation hybrids to maximize the benefits of heterosis. Therefore, one of the most important problems of sericulture is solving the problem of accurately separating breeds intended for hybridization by sex, in order to obtain pure hybrids that are not contaminated with the original breeds. The currently used methods for dividing grenas, caterpillars, cocoons, pupae, and silkworm moths by sex are very labor-intensive and inaccurate. However, in Uzbekistan, at the Scientific Research Institute of Sericulture, using genetic engineering methods, sex-determined breeds of silkworms have been created, which are easily and accurately divided according to the color of the eggs into females (dark moth) and males (light moth) using a special apparatus. This allows you to significantly reduce the cost of green production and, using the purity of preparation of hybrids, increase the yield of cocoons.
