The results of former research concerning the development of inbred lines in native silkworms breeds, established the technologic formation procedures and pointed out reduced values of inbreeding depression in the productive characteristics. The object of the present research aims are the identification and selection of the most productive inbred lines based on crossing with tester constant lines, namely the research of general combining capacity; establishing specific combining capacity by direct and reciprocal crossing and estimation of heterosis effect. The results of research emphasize that from those 14 inbreeding lines tested for combining capacity, 7 and 10 maternal lines and 3 paternal lines obtain heterosis results that demonstrate superior possibilities of turning into account the crossbreeding system in silkworms raising. The heterosis effect is obvious important foe shell weight.
