The Improvement of Unique Economic Indicators in Georgian Breeds of Mulberry Silkworm

Abstract

Methods of improving the viability of Georgian breeds of silkworm (Digomi 1 and Digomi 2) with excellent properties are considered in the work. The cocoons of the breeds of the initial Digmuri group are characterized by a long thread (2000 m) and high silkiness (24-25%). The only disadvantage of these breeds is that they have a relatively low viability, and this work was carried out just to improve this deficiency. As a result of carrying out complex selection work to increase the viability of the initial breeds, new improved hybrid combinations were obtained, which in their biotechnological properties are equal or higher than the initial breeds.
