Comparative Study of Biological Characteristics of Larvae, Crude and Dried Cocoon in 7 Races of Silkworm Bombyx mori L., Raised in Transylvania Area

Abstract

7 monovoltine races of Romanian silkworm Bombyx mori L. were breeded in specific Transylvania conditions, assuring the same microclimate conditions, being fed with the same mulberry leaves (Ukraina 107). The results obtained showed a high homogeneity, the differences were due to the variability and genotype characteristic for each individual of every race. Results and standard deviations are within the race standard. The study permitted a ierarchy of the races, following the biological characteristics, microclimate conditions, quantity, quality and breeding technology.
