Random amplified polymorphic DNA (RAPD) and inter-simple sequence repeats ( ISSR) methods were used to study the germplasm resources of Lycoris longituba. Using RADP with 12 primers, a total of 77 discernible loci were obtained, of which 53 loci were polymorphic ( PPB = 68 .8% ) . Using ISSR with 9 primers, 67 disernible loci were obtained, of which 62 loci were polymorphic (PPB = 92 . 5% ) . The results indicate that genetic diversity of Lycoris longituba
is abundant, therefore , it is a good genetic material to store for breeding purpose . From UPGMA dendrograms, three Lycoris longituba types were recognized , which could be also distinguished by their flower colors . For future use , different varieties of Lycoris longituba could be cultivated .
