The study has been carried out at the Sericulture and Agriculture Experiment Station Vratsa during the period 2011 – 2012 with silkworm F1 hybrids, created by sex-limited for cocoon color and larval markings breeds. The results obtained manifested that the fresh cocoon weight, silk shell weight, and silk shell percentage values in the four-way hybrids were lower, but in the single hybrids they were close to the control values. The two new, sex-limited for cocoon color silkworm F1 four-way hybrids manifest silkworm viability and productivity, comparable with the control, which makes them suitable for commercial rearing.
