Many banana cultivars (including the Plantain type) are triploid interspecific hybrids between Musa acuminata (A genome) and Musa balbisiana (B genome). M. balbisiana contains endogeneous Banana streak virus sequences (eBSVs) that can, in interspecific genome context, spontaneously release infectious viral genomes. We analyzed, a triploid progeny of 184 individuals from a cross between a ...
