A set of 74 polymorphic RAPD bands was used to generate the genetic similarity index among the 42 accessions of Barberton daisy genotypes.
In the present study, we have found genetic similarity indices inferior to those from the work by Chung et al. (2001), to our knowledge, the only study of gerbera genetic variation using RAPD markers.
The authors used the afore mentioned index (Jaccard) to analyze the genetic diversity of Gerbera hybrida and found an average of 0.72, in comparison to the average index of 0.55 calculated for our data.
Similarly, the range of the index ranged from 0.50 to 0.90 in contrast to the range of 0.28–1.00 in the present study, suggesting that the accessions investigated in our study are more divergent genetically than those employed in the earlier study.
