摘　　要：以从国外引进的3个勋章菊品种‘红纹’、‘日出’、‘星白’与在国内收集的不同花色中国勋章菊及其杂交后代共12个花色勋章菊植株为材料,观察其花瓣形态与种子外观的差异,并利用SDS-PAGE技术分析不同花色勋章菊种子蛋白条带存在的差异。结果表明:勋章菊花色丰富多彩,花心多具有黑色、褐色或白色的眼斑;不同花色品种的勋章菊种子外观形态差异较大;12个品种的勋章菊种子蛋白条带大致相同,但存在一些特异条带,能够清晰地反应出个体之间的差异。Taking Gazania rigens L. ＇Daybreak Red Stripe＇, ＇Sunglow＇, ＇Mini Star White＇ which introduced from Japan and some other varieties collected in China （totally twelve kinds） as materials, the differences on petal morphology and seed appearance between them were observed. SDS-PAGE technique was used to observe the differences in protein bands among twelve varieties, in order to explore the possibility to distinguish the genetic relationship and classification of different varieties by seed. The resuhs showed that petals of Gazania rigens L. were rich in color,and mostly there were some black, brown or white eye spots at the base of the ray flowers. The seed appearance of the morphological of twelve varieties were different among each other. The seed protein of twelve varieties ,were with^roughly the same protein bands, but there existed some specific bands could clearly reflect the differences between individuals. That a possibility to investigate the genetic relationship between the different varieties were provided.
