摘　　要：以麝香百合系的18种基因型为试材,采用试验地测量的方法对株高、茎粗、叶数、叶长、叶宽、花蕾数、花长、花径8个性状进行分析。结果表明:基因型在各形态性状上均存在差异,多样性较丰富,但是变异不大;各形态性状之间具有密切的关系,在生长过程中相互影响比较大。综合多个性状,整体上表现较好的基因型有:"K1-4"、"M"、"C"、"Q1-3"、"59"、"46-2"、"17-2"、"K早"、"白森林"。建议将株高、花长、花径、叶数及叶面积等作为品比试验的指标。Morphological characters of 18 genotypes of Liliurn longiflorurn were analyzed. The results showed that there were rich diversity and close relationship on morphological characters of 18 genotypes, but the variation were small. It could be concluded that the morphological characters of genotypes ＇K1-4＇,＇ M~, ＇C＇, ＇Q1-3 ~,＇ 59 ~, ＇46-2 ~,＇ 17-2 and ＇ White Forest were good. The results of analysis showed that plant height, flower length, flower diameter, the number of leaves and leaf area were the important factors in the variety evaluation.
