Evaluation of productive performance of 51 different peanut cocoon strains of Iran silkworm Bombyx mori (Lepidoptera: Bombycidae) germplasm

Abstract

In our study, 51 peanut strains of Iran silkworm germplasm were evaluated for 36 economically important traits and for the feasibility of using these strains for breeding programs. After hatching of eggs, neonates were brushed and reared up separately on fresh leaves of mulberry (Morus alba). Newly
hatched larvae of all strains were reared for experiment. Individual egg laying were prepared for each strain before rearing and each individual egg laying consisted of about 500 eggs taken from one disease free laying and decreased to 250 larvae at the beginning of the 4th instar.
