progeny generation
1.The generation interval of current breeding scheme is 4.48 years, ratio of input and output is 1:14.04, the number of ram progeny test is low, and the useful life of ram and ewe is longer and so on can be improved.
2.In the subsequent generation, these inserts could segregate away from each other, allowing the selection of the progeny plants with only the Xa21.Using the DRB binary vector system, We abtained 41 transgenic plants , including japonica restorer line C418 and indica restorer line shuhui 527, chuanghui 11 .PCR and Southern blot analysis revealed that forein gene were intergrated into the genome of these plants.
