三对春用蚕品种的比较试验

Comparison Test on Three Silkworm Races for Spring Rearing

本文以现行当家品种育松×皓月为对照，对春用品种华丰×雪松和苏镇×春光在茧丝质和抗氟性方面进行了比较试验。结果发现：两对试验品种在丝质和抗氟性方面均优于或略优于对照种．故建议在氟化物污染严重地区推广这两对品种以确保稳产高产。

Huafeng ×Xuesong and Suzhen ×Chunguang were compared with a control Jingsong×Haoyue which popularized in current cocoon production in the aspects of cocoon and silk quality and the resistance to fluoride. The results showed that Huafeng ×Xuesong and Suzhen× Chunguang were superior to the control in the resistance to fluoride,and slightly better than control in cocoon and silk quality. Hence,it was suggest-ed that the two tested varieties should be employed in the areas polluted by fluoride frequently so as to ensure the safe and high yield cocoon production.
