摘　　要：通过对柞蚕新品种墨玉及其杂交种辽蚕988的缫丝性能测定,明确了新品种的缫丝性能。柞蚕新品种墨玉雌茧的茧丝长1533.6 m、丝重1.03 g、纤维公量1.36 g,分别比对照种三里丝高19.9%、25.61%和20.35%,与对照种抗大的8个缫丝性状相当或略优于对照种;雄茧的茧丝长1520.1 m、丝重0.95 g、纤维公量1.26 g,分别比对照种三里丝高20.62%、26.67%和26%,与对照种抗大的缫丝性能相当。杂交种辽蚕988除在茧丝纤度与茧丝量方面略低于墨玉×9906外,其余缫丝性状与对照种抗大×9906及杂交组合墨玉×9906之间均无显著性差异。新品种墨玉及其杂交种辽蚕988的鲜茧出丝率均超过7%,达到了缫丝性能评价的优级标准。The reeling performance of the new variety of tussah silkworm,Moyu and its hybrid,Liaocan 988,was determined to clarify the reeling performance of the new variety.The total silk length of female cocoons of Moyu was 1533.6 m,silk weight 1.03 g and fiber metric 1.36 g,which were 19.9%,25.61%and 20.35%higher than those of the control species Sanlisi,respectively,and were equivalent to or slightly better than those of the control species Kangda in eight reeling traits.The total silk length of male cocoons was 1520.1 m,silk weight 0.95 g and fiber metric 1.26 g,which were 20.62%,26.67%and 26%higher than the control species Sanlisi,respectively,and the reeling performance was equivalent to that of the control species Kangda.The reeling performance of the hybrid Liaocan 988 was equivalent to that of the control Kangda×9906 and Moyu×9906,except for the silk size and silk quantity,which were slightly lower than those of the combination Moyu×9906.The fresh cocoon silk yield of both new variety Moyu and its hybrid Liaocian 988 exceeded 7%,which reached the superior standard of reeling performance evaluation.
