The present study involved the regularity of inheritance of basic productive indexes (viability of larvae, cocoon weight, cocoon shell weight, length of silk filament and raw cocoon yield per 1 box) of F1 reciprocal hybrids with the participation of genetically sex-marked silkworm races at egg and larva stages.It was established that the use of genetically sex-marked silkworm breeds at egg and larval stages as maternal and paternal forms in industrial hybridization influenced the inheritance of the indexes of viability of larvae, cocoon weight, cocoon shell weight, length of silk filament and raw cocoon yield per 1 box of silkworm eggs.
