Two hybrids between Oryza sativa and O. glaberrima were studied for chromosome pairing at meiosis. In both the hybrids pairing was normal at pachytene. In one of them, desynapsis results in low bivalent formation in diplotene and metaphase stages: The significance of these observations is discussed in relation to the nomenclature of genomes and phylesis.
