波兰桑蚕品种的综合评价与聚类分析

Comprehensive Evaluation and Clustering Analysis of Poland Silkworm Varieties

为丰富和创新桑蚕种质资源,辽宁省蚕业科学研究所先后从波兰引进10个桑蚕品种(品系)进行性状调查与聚类分析,确定引进品种的地区适应性和亲缘关系。结果表明:波兰桑蚕品种(品系)KBDA和KBDB综合性状表现最优,波黄A的综合性状表现较差;从波兰引进的10个品种(品系)被归为一类,这10个品种(品系)与辽宁地区的现行桑蚕品种有着较远的亲缘关系。

To enrich and innovate the silkworm genetic resources, Liaoning Provincial Scricultural Institute has introduced 10 silkworm varieties （strains） from Poland to conduct investigation on their characters and clustering analysis, and to determine the local adaptation and genetic relationship of these introduced varieties （strains）. The results show that the varieties （strains） KBDA and KBDB revealed superior comprehensive characters, but Pohuang A is inferior; the 10 varieties （strains） introduced from Poland were classified into the same category, and they have distant genetic relation- ship with the existed silkworm varieties in Liaoning area.
