Assessment of Embryonic and Postembryonic Vitality of F3 Progenies Obtained Under Unfavorable Stress Conditions of Breeds and Systems

In this article, in 2018–2020, with the participation of scientists from the laboratory “Breeding, Ecology and Prevention of Chemical Poisoning of Mulberry Silkworm” of the Research Institute of Sericulture, in order to study the reaction of existing breeds and hybrids of silkworms to stress factors, differentiation of adaptive genes in the silkworm organism and their selection method the results of the sampling experiment are analytically studied. In the experiment, adverse conditions limited to the norm were artificially established in order to study the adaptation characteristics of the mulberry silkworm Marvarid, Gozal Ipakchi 1 and Ipakchi 2 breeds and the selection systems of Line 27 and Line 28 in case of limiting the amount of nutrients, one of the main factors.
