摘　　要：对33份不同来源的菠菜种质资源的11个质量性状和6个数量性状进行了研究,结果表明,33份菠菜种质材料间数量性状的变异系数在29.07%~78.97%,单株质量的变异系数最大,叶长的变异系数最小,不同性状在不同材料间表现出不同程度的多样性。通过聚类分析将33份菠菜种质分为2大类群,进一步分为6个组群,各组群具有一定的形态学特征。其中,第Ⅲ组群小尖叶、武平菠菜、汝阳大圆叶和第Ⅵ组群大尖叶、黑叶菠菜形态学优势明显,可分别作为选育高产植株和小型植株的优良材料加以利用。The morphological traits including 11 qualitative characters and 6 quantitative characters were investigated from 33 spinach（ Spinacia oleracea L. ） germplasm resources. It was found that the variation coefficient of the 33 spinach germplasm resources was from 29. 07% to 78. 97%,the variation coefficient of plant weight was the biggest,and the variation coefficient of leaf length was the smallest. The extent of diversity were different among the different traits from different varieties. Two big groups were divided from these 33 spinach germplasm resources by cluster analysis, furthermore divided into 6 groups, and each group had some definite morphological characters. The advantage of morphological traits of group Ⅲ（ Xiaojianye,Wupingbocai,Ruyangdayuanye） and Ⅵ（ Dajianye,Heiyebocai） were prominent,which could be used as materials for high yield and small size spinach breeding.
