Banana bunchy top disease is caused by the Banana bunchy top virus (BBTV), which is a species of the genus Babuvirus in the family Nanoviridae. In this study, we collected 61 isolates of BBTV from Sumatra Island. The sequences of DNA-R and DNA-S of 61 samples and DNA-U3 of 37 samples were determined. Although the Sumatra population has different sequences in the stem-loop region in DNA-U3, it is generally very similar, with little or no variation according to planting area or the varieties and genome types of the host. The comparison of sequences between Sumatra isolates and those from other areas showed that the sequence identity with the Asian group is higher than with the South Pacific group. The genetic analysis showed that the Sumatra population has very low diversity compared with other areas. Recombination analysis revealed that there was no evidence of recombination in the Sumatra population. The selection pressure analysis indicated that all Sumatra populations received negative selection. The selection pressure among the viruses infecting the banana varieties having the genotypes of AAB or ABB received a slightly weaker negative selection than that of the viruses infecting the varieties with AA or AAA genotypes. A neutrality test suggested the sudden expansion of the West Sumatra population. This is the first report to survey the BBTV on Sumatra Island.
