Eighteen ISSR primers (between Simple Repeated Sequences) were used to estimate the genetic diversity of Angolan cassava populations in order to identify genetic variabilities and their potential to be used in the diversification of cassava crops in Angola. In order to do so, three populations from three Angolan provinces were analyzed (Cuanza Norte, Uige and Malanje), which totaled 40 genotypes. In total, 116 bands were amplified with 93.24% polymorphism and 6.4 markers per ISSR primer, on average. Nei?s gene diversity (H) and Shannon indices (I) applied to the analyzed accessions presented values ranging from H = 0.20 to 0.24 and I = 0.29 to 0.50 which are intermediate values. The total gene diversity (HT) was 0.3113, and it showed high heterozygosity in Manihot populations; this outcome indicated that these populations presented gene variability. ANOVA showed 10.41% total variance between populations and 89.59% within them. Molecular featuring revealed gene diversity in each of the assessed populations; there was gene structuring between populations. |
