In the Institute of Forestry and Wood Industry in Belgrade - Yugoslavia in 1990 year, 19 races of silkworm were reared, which eggs were imported from Bulgaria. The results of statistical analysis of a few qualities of silkworm, as: hatching, production of cocoons, diameter and length of cocoons and silkness have shown the existence of statistically significant differences between races, i.e. their expressed genetical polymorphism. Better results in respect to the remaining races have shown: Hebar 1, Ukrainska 13, Taskenskaja 15, Vraca 1, No 371. However in the process of hybridization and selection breeding the importance of the remaining races is not disparaged, their genetical wealth and variability being the basis of any breeding.
