KẾT QUẢ KHẢO NGHIỆM GIỐNG TẰM LAI TỨ NGUYÊN LƯỠNG HỆ MỚI LĐ-09 TẠI LÂM ĐỒNG

This research was conducted in 3 key sericulture production locations in Bao Loc, Di Linh and Lam Ha during both dry season and rainy season in 2013 in order to define adaptability of new bivoltine double-cross silkworm hybrid LD-09. As a result, new silkworm hybrid LD-09 is welladaptable to conditions in Lam Dong. All the indexes such as the percentage of live pupae, cocoon yield, cocoon and silk quality of LD-09 are equivalent to control race LQ2: The percentage of live pupae reaches over 90% and 87% in dry season and rainy season respectively. Average cocoon yield is over 40kg/box, average weight of one cocoon is 1,61g, weight of one cocoon shell is higher 0,32 g, the percentage of cocoon shell is higher 20%, filament length is between 900 and 1000 m, reelability reaches about 90% and 80% in dry season and rainy season respectively, silk quality meets international grade 4ª.
