摘要：

为了解决盾叶薯蓣人工生产中良种缺乏的突出问题，本研究以盾叶薯蓣为研究对象，对不同品系间叶、茎、根状茎的形态特征、开花特性和单株根状茎产量等指标进行比较和分析。结果表明：盾叶薯蓣品系间在形态上具有丰富的多样性，这为盾叶薯蓣的良种选育奠定了基础。在参试的20个品系中，盾薯38综合表现较为突出，产量和质量均优于其他品系。

Abstract:

In order to solve the problem on the absence of elite, Dioscorea zingiberensis wright were used as materials in this study. The article inspected morphological characteristics of leaf, stem, root stock , flowering characters and yield. The results indicated: Dioscorea zingiberensis wright has abundant multiformity.The multiformity was useful for the seed breeding .dunshu38 was the best strain .The yield and quality of dunshu 38 was better than other strains.
