摘要
家蚕平面丝均匀度的优劣直接影响平面丝产品的质量．为探明家蚕品种间平面丝均匀度的遗传性差异，用单位面积丝重量的变异系数对菁松等１４个春用、夏秋用蚕品种以及薪杭×科明等８个一代杂交种吐成的平面丝的均匀度进行了研究．结果表明，平面丝均匀度在蚕品种间存在显著差异，一代杂交种的平面丝均匀度在不同的杂交组合及同一杂交组合的正反交之间均有差异。
The uniformity of flat way silk has direct relations with the quality of flat way silk products.Uniformity of flat way silks spinned by 14 silkworm varieties and 8 F1 hybrids was studied in our experiment performed in 1995 in order to tell the difference decided by genetic factors.The result showed the uniformity of flat way silk significantly different among varieties and varied with both hybrid combinations and even a same combination in reciprocal cross,that seemed to be mainly influenced maternally.
