Abstract

VASILEVA, Y., N. PETKOV, Z. PETKOV, A. MATEI, L. MARGHITAS and G. DINITA, 2004. Combine ability evaluation of perspective Bulgarian and Romanian silkworm (Bombyx mori L.) races. Bulg. J. Agric. Sci., 10: 253–256

This study was made to evaluate the best hybrid combination between perspective Bulgarian and Romanian silkworm races. From the complex evaluation it was determined that BanjasaAlba Kom1 (Japanese type) and Banjasa75 Vratza40 (Chinese type) are the most perspective for creation of new synthetic selection populations. Banjasa75 Kom1 and BanjasaAlba Vratza40 hybrid combinations are of great interests for industrial cocoon production.

Key words: combine ability, races, silkworm, hybrids
