| Abstract: | Cytology of 415 BC 2F 1 and BC 1F 2 plants in crosses, Oryza sativa cv. 02428 vs. two accessions of O.eichingeri from Uganda, were studied. 155 monosomic alien addition lines and 184 introgression lines were identified. Further studies showed that 28 monosomic alien addition lines and 48 introgression lines were resistant to brown planthopper. |
