Study on the effect of gamma-radiation on the development of silk worm (Bombyx mori L.)

These investigations are of special interest to the breeding practice considering the lack of profound research activity. The main purpose was to find out possibilities of using gamma-rays as a mutagenic factor in sericulture. The results obtained show that the irradiation of silk worm eggs at b 2 stage of embryo development with 5 Gy stimulates the biological development. The irradiation doses of 10-25 Gy inhibit mulberry silk worm development. The different species react in different way. Probably mutation forms are to be sought within 10-25 Gy doses. 10 refs., 3 tabs. (author)
