摘　　要：采用添食病毒的方法，对200个家蚕品种进行了抗浓核病调查，发现28个抗病品种，并从秋丰、白玉中选育出抗浓核病品系黑抗、白抗；进而把眼纹全黑基因（bl）导入抗病个体，第15染色体上同时具有抗浓核病基因（nsd－Z）和斑纹基因眼纹全黑（bl），从而育成了带斑纹标志的家蚕抗浓核病育种材料D01、D02。创建了利用斑纹基因作遗传标记，不用添毒的抗浓核病品种选育方法。200 silkworm varieties were investigated on their resistance to densonucleosisthrough oral administration of the pathogen. It was discovered that 28 of them had theresistance. The resistant lines, namely 'black resistant' and 'white resistant',were se-lected from Qiufeng and Baiyu. Furthermore, bl(gene of blind silkworm) was introducedinto the resistant individuals, making chromosome 15 possess both nsd-Z(densonucleo-sis resistant gene) and eye-spot gene bl. Two breeding materials(D01 and D02)resistantto densonucleosis were obtained. This approach creates the possibility for breeding den-sonucleosis resistant varieties with eye-spot as genetic marker instead of administratingthe pathogen to silkworms.
