【摘要】 试验结果表明，目前在广西推广的桑蚕“两广二号”杂交种，其母蛾交配后，在室温２５℃产卵与室温３０℃产卵相比较，正交（９３２·芙蓉×７５３２·湘晖）在２５℃条件下，产出卵率高３．８８％ ，不良卵率降低１．１８％ ，反交（７５３２·湘晖×９３２·芙蓉）产出卵率高４．７６％ ，不良卵率降低１．８７％ 。更多还原

【Abstract】 The results showed that the egg laying rate of the hybrid of the “Liang guang ”No.2,Which is expanded in GuangXi at present was lower at 25℃ than at 30℃ after mating. The egg laying rate of the positive hybrid ( 932·Fuyong×7532·Xianghui) was 3.88% higher at 25℃ than at 30℃,the poor eggs reduced by 1.18% . The egg laying rate of the reciprocal hybrid (7532·Xianghui×932·Fuyong) was 4.76% higher at 25℃ than at 30℃,the poor eggs reduced by 1.18% .更多还原
