摘要 收集27个玉簪属品种进行形态生长指标、栽植成活率及生长分株数的观测记录，通过成活率高低及分株能力初次筛选到20种，筛选的玉簪品种分为4个叶色类型，即黄色叶、花色叶、绿色叶、蓝色叶。耐阴试验表明，结合品种形态生长指标最终筛选到12种，确定4个叶色类型及每个类型适合推广应用的品种。

Abstract 27 species of Hosta were collected to observe and record the morphological growth index， planting survival rate and the number of growing branches. Through the survival rate and branch ability， 20 species were screened for the first time. The screened Hosta varieties were divided into four leaf color types， namely yellow leaf type， flower color leaf type， green leaf type and blue leaf type. The shade tolerance test showed that combined with the morphological growth index of varieties， 12 varieties were selected， and four leaf color types and varieties suitable for popularization and application of each type were determined.
