大麦种质资源的数量分类研究
QUANTITATIVE CLASSIFICATION RESEARCH INTO BARLEY GERMPLASM MATERIALS
【摘要】 本文以品种主成分欧氏距离为基础,对100份大麦种质资源的主要农艺性状和籽粒蛋白质含量等11个数量性状进行了系统聚类分析,初步划分为5大类群,并对其基本特征进行了讨论。
【Abstract】 Based on the Euclidean distance of principle components among germplasms, this paper systematically conducts clustering analysis of 11 quantitative characters of the main agronomic characters and the content of powdery protein in 100 portions of germplasm materials, These samples are primarilly divided into five groups, there characteris- tics are also dealt with.
