Genetic variation among accessions of the genus Manihot by ISSR markers
The objective of this work was to evaluate the genetic diversity within and among accessions of Manihot by using ISSR markers. Five species and two varieties of Manihot, besides two species of the genus Croton, used as the out-group, were analyzed by using 20 oligonucleotide (Olii) ISSR UBC primers. To analyze the similarity index between species and accessions, the Jaccard and simple matching coefficients were used. The 20 Olii tested were highly polymorphic in all species analyzed, and 89.7% of the loci were polymorphic. A higher genetic variability is observed among different species of Manihot, such as M. dichotoma var. undulata and M. caerulescens, than among individuals of the same species, such as M. dichotoma and M. dichotoma var. undulata.
