Abstract: 【Objective】Assessment of genetic distance of the parents was essential work to ensure the heterosis of F1 seeds. In order to select the right lines for crossing of Tagetes plant, 【Method】the genetic relationship of 18 inbred lines of Tagetes was analyzed with ISSR markers and morphological traits. 【Result】With 10 ISSR primers, 138 polymorphic loci were detected out of 145 loci in total. Although the results obtained by ISSR and morphological traits were generally similar, there were some differences. 【Conclusion】ISSR markers could provide genetic basis for select inbred lines as crossing parents of Tagetes according to the genetic distances.

Key words: Tagetes, inbred line, genetic distance, ISSR, morphological trait
