】 Cytological studies of cultivated rice 02428 and BC2F1 and BC1F2 generations of tight-panicle wild rice originating from Uganda were carried out, and 155 heterologous addition lines and 184 translocation lines were isolated. Characterization of BPH resistance showed that, 28 monomeric heterologous additions and 48 translocations showed insect resistance.
