摘要
本文报道了野蚕辐射不育效应的研究。用６０Ｃｏγ－射线处理野蚕蛹，成虫的羽化率随剂量的增加而减少，其关系式为ｙ＝８７２６６８８ｅ－００８４４ｘ，畸形率随剂量的增加而增加，其关系式为ｙ＝１１６９２１ｅ０７８０９ｘ，剂量在４５ｋａｒｄ以内对雄成虫寿命无明显影响；在４５ｋａｒｄ以内对成虫产卵量无明显影响，卵的不育率随剂量的增加而增加，其关系式为ｙ＝９３００６８ｅ－１０５８３ｘ。根据Ｆ１代辐射遗传不育效应的研究认为，野蚕的亚不育剂量为２５ｋｒａｄ，在亚不育剂量下，不同日龄蛹之间的辐射不育效应均无明显差异。
This paper deals with the effect of radiation sterility on wild silkworm The matured pupae of the insect were treated with 60 Co γ-ray The emerging rate of the adult insects decreased with the increase of dosage as indicated by the correlation formula: Y=87 26688e -0 0844x The deformity rate increased with the increase of dosage and the formula was Y=1 6921e 0 7809x The life-span of the male moths was not affected obviously within the dosage of 50 krad, and the egg numbers of oviposition was not influenced apparently within the dosage of 45 kard The sterile rate of eggs increased with the increase of dosage, as shown in the following formula: Y=93 0068e -1 0583x According to study on the effect of sterile inheritance of F 1 treated by radiation, the sub-sterile dosage for wild silkworm was determined to be 25 kard, under which the effect of radiation sterility differed little between different day-old pupae treated
