Breeding and field performance of Xa21 transgenic japonica variety Shengdao301 |
| |
| Abstract: | Using a genetic transformation system mediated by Agrobacterium tumefaciens, Xa21 gene against the bacterial blight disease was introduced into calli of a japonica variety Shengdao301 cultivated in Shandong Province. Based on Gus detection, marker assisted selection and inoculation from T_0 to T_5 generation, a great number of homozygous transgenic Shengdao301 plants were obtained. Performance of field resistance and agronomy traits were investigated. |
