柞蚕新品种“墨玉”的选育

Breeding of A New Tussah Variety“Moyu”

为解决我国北方二化性柞蚕产区柞蚕品种辨识度低等问题,辽宁省蚕业科学研究所以具有幼虫期典型体色性状的8822和具有成虫期典型标记性状的H8701为亲本,选育出兼具幼虫期和成虫期典型性状特征的柞蚕新品种“墨玉”。新品种幼虫体背为宝石绿色,成虫前翅前缘脉呈黑紫色。新品种具有对北方低温多湿气候适应性强,茧型中等,抗病丰产等优点,繁种试验比对照品种抗大春季增产9.08%、秋季增产9.87%。

To solve the problem of low rate of identification of tussah varieties in northern China,a new variety“Moyu”was bred by Liaoning Provincial Sericultural Institute with parents of 8822 which has typical dark green body color in silkworm stage,and H8701 which has unique dark purple color on top edge.The new variety inherited both parent’s marker traits,namely,dark green body color in silkworm stage and dark purple color on top edge of its adult’s forewings.Possessing high adaptability to low temperature and high humidity of northern climate,“Moyu”shows higher disease resistance and productivity,and produces middle-sized cocoons.The seed reproduction experiment shows that the yield of“Moyu”increased by 9.08%in spring and by 9.87%in autumn.
