用二氧化碳激光器66焦耳照射柞蚕卵,在大量伤害下,获得早熟存活个体,经过选育后,小区试验全龄期缩短1～2天,发病减轻24～50%,茧层量提高5～18%,茧层率达到13%,经国营蚕场试养,比现行品种斤卵产茧量提高6.79%,绝对茧层率提高0.5～1%,累计增产12.72%,在农村丝茧生产试养,斤卵产值比现行品种提高13.67%,为早熟多丝量柞蚕新品种,经1985年4月品种鉴定会评审后通过。
Cotyledon eggs were irradiated with Joule 66 carbon dioxide laser, and under the condition of a large number of injuries, the individuals of premature survival were obtained. After breeding, the cell cycle shortened by 1 to 2 days and the incidence decreased by 24 to 50% and the cocoon layer level increased by 5 to 18% , The cocoon rate reached 13%. After the trial run by the state-owned silkworm farm, the cocoon yield increased by 6.79% and the absolute cocoon shell rate increased by 0.5-1% compared with the current varieties. The cumulative increase of 12.72% in cocoon production trial, Kg egg production value than the current varieties increased by 13.67%, for the premature multifilament tussah new varieties, by the April 1985 species identification will be passed after the appraisal.
