Dependence of silkworm productivity indicators on life expectancy of butterflies

In this article, the current state of silkworm breeding in Uzbekistan is highlighted by the fact that cocoons, raw silk and silk products grown are not competitive enough. About the role of selection in increasing the volume of cocoon cultivation and improving its quality. This includes ways to influence the genetic characteristics of newly created breeds and their hybrids, which contribute to the improvement of cocoon productivity and technological performance. The importance of population-specific laws, as well as the methodology of experiments, the degree of interdependence of selection traits, experiments in two groups of silkworm breeds and systems, in three gradations, and the results obtained on them. Prospects for the application of experimental results in science and practice are also discussed
