摘　　要：印度泰米尔纳德邦蚕区饲养二化性和多化性家蚕品种。依据该地区蚕茧市场蚕茧检测中心2006—2010年对蚕茧缫折及相关指标的测试数据进行统计分析,比较影响二化性品种和多化性品种蚕茧缫折的主要因素。统计分析显示,多化性家蚕品种蚕茧的缫折较高,主要是受次茧率的显著影响;尽管近年来二化性家蚕品种的次茧率也明显增加,但高次茧率对其缫折的影响并不显著,这是因为对缫折有明显影响的茧层率在过去的5年里得到显著提高。结果提示,泰米尔纳德邦饲养的二化性家蚕品种具有高茧层率和低缫折的优势。Tamilnadu province continues to stand first in bivoltine silk production in India for the third consecutive year. In order to understand factors influencing estimated renditta of bivoltine cocoons produced in comparison with multivoltine co- coons, the cocoon testing data generated from 2006 to 2010 in the Cocoon Testing Centre （CTC） established in the Gov- ernment Cocoon Market were statistically analyzed. It is found that multivoltine cocoons has higer estimated renditta, which was significantly influenced by defective cocoon percentage. In spite of the fact that the defective cocoon percentage of bi- voltine cocoons has significantly deteriorated, high defective cocoon percentage had no significant influence on estimated renditta of bivoltine cocoons. This is due to the fact that the shell ratio, which also considerably affects the expected rendit- ta, in the last five years, is found to be consistently improving. These results demonstrated that bivoltine cocoons produced in Tamilnadu had high shell ratio and low estimated renditta.
