用人工饲料育进行家蚕一代杂交种的杂交率检验初报

A Primary Report on the Examination of Hybrid Rate of F_1 Hybrid Silkworm Eggs by Artificial Diet Rearing

用人工饲料育对21个家蚕品种进行了调查,收蚁24h疏毛率最高的是菁松×皓月,达到9988%,最低的是春·蕾×锡·,为7807%,大部分品种收蚁48h疏毛率达到98%以上。分析供试家蚕品种的蚁蚕疏毛率、杂交率的检验结果和饲料成本认为,菁松×皓月、春·蕾×镇·珠、苏·镇×春·光、鲁7×9202、781×782·734、871×872等适合用人工饲料育进行一代杂交种的杂交率检验。

During 24 h from the beginning of rearing, the setae dispersion rate of the larvae was over 98% in the 15 silkworm varieties investigated. The variety with the highest setae dispersion rate was Jingsong×Haoyue,99.88%, and the lowest one was Chun·Lei×Xi·Fang,78.07%. Based on the analysis of setae dispersion rate, hybrid rate of the 21 silkworm varieties investigated and the cost of artificial diet, we concluded that Jingsong×Haoyue, Chun·Lei×Zhen·Zhu, Su·Zhen×Chun·Guang, Lu 7×9202, 781×782·734, 871×872 and so on, were comperatively suitable for testing the F_1 hybrid rate by artificial diet rearing.
