| 摘 要： | 选用066、781、446、785四个柞蚕品种进行复式杂交,自1980年至1989年经20代选育,育成了早熟、体强的烟6柞蚕新品种;选用激光诱变材料2H30、方青、河南6号三个品种制成三元杂交材料,自1978年至1989年经23代选育,育成了多丝量789柞蚕新品种。烟6、789是一对优良杂交组合,经五年农村放养比对照种产量高,品质好,公斤卵产茧量增产10.87％,公斤卵产值提高15.94％。

| Abstract: | A new variety of Antheraea pernyi-Yantai No. 6 characterized by early-ripe and strong was bred out by using cross - breeding method,among four Chinese tusser varieties:C66, 781,446, 785 through 20 generations, And by using three varieties; 2H30 (bred through laser induction), Fang-qing,He'nan No. 6 as three parent strains,The other new variety-789 rich in silk was bred out through 23 generations during 1980-1989.
It's found that Yantai No. 6 X 789 exhibited a good specific combining ability. We found that the silk yields of the new variety is higher than that of the check variety and its silk quality is better than that of the check variety. Its cocoon yields per kg eggs is 10. 87% higher than that of the check and its income per kg eggs is 15. 94% more than that of check variety. |
