为了究分利用柞蚕杂交种优势,使春秋蚕生产用种实现杂交种化,促进柞蚕生产向高产稳产方向再跨进一步。1986年我们从山东蚕业所引进(烟6×789)F_1代种卵,在海城市接文镇王家堡农业现代化基点村与当地推广的杏黄、青六号品种进行春秋蚕的试验和比较。烟6×789是由烟6和789两个黄蚕品种杂交而成。其中烟6有早熟、抗病、体质强健的特点。789是一个中熟、生命力强、多丝量的新品种。烟6×789是一对杂交优势较强的丰产型杂交组合。经1986～1988年3个春秋蚕期的对比试验。(烟6×789)F_1平均孵化率为96.4％,比杏黄
In order to study the advantages and disadvantages of using tussah hybrids, the production of spring and autumn silkworms to achieve hybridization of seed, and promote the production of tussah to the direction of a high yield and then go further. In 1986, we introduced the F1 hybrids (Yan 6 × 789) from Shandong Sericulture Co., Ltd., and tested and compared the Spring and Autumn silkworms in the base areas of Wangjiabao Agricultural Modernization Base Village, Jiewen Town, Haicheng City and the locally-promoted varieties of Xinghuang and Qingliu. Smoke 6 × 789 by the smoke 6 and 789 two yellow silkworm breeds. Among them, tobacco 6 has precocious, disease-resistant and strong constitution. 789 is a mature, strong vitality, multi-wire new varieties. Smoke 6 × 789 is a pair of hybrids with strong yield hybrids. After 1986 ~ 1988 three spring silkworm comparative test. (Smoke 6 × 789) F_1 average hatching rate was 96.4%, compared with apricot yellow
