摘要: Cultivated sugarcane clones (Saccharum spp., 2n= 100 to 130) are derived from complex interspecific hybridizations between the species S. officinarum and S. spontaneum. Using comparative genomic DNA in situ hybridization, we demonstrated that it is possible to distinguish the chromosomes contributed by these two species in an interspecific F1 hybrid and a cultivated clone, R570. In the interspecific F1 studied, we observed n+ n transmission of the parental chromosomes instead of the peculiar 2n+ n transmission usually described in …
