Wang Dezheng et al (Rice Research Institute, AAAS, Hefei 230031)  
The breeding development of Japonica hybrid rice in Anhui province for 23 years was described in the paper. In the study, there were not only some breeding experiences in breeding of BT type Cytoplasmic Male Sterility(CMS) line, Photo(thermo) Sensitive Genic Male Sterility(PGMS or TGMS) line and restore line, but also description of characteristics, high-yielding seed production techniques and application values for mainly three-line and two-line hybrids.Future reseraching strategies will be to improve morphological and phtotsynthesis characteristics of the hybrid for exploiting the heterosis of Puter -subspecific hybrids.On the other hand,the farmers' skill for planting high-yielding of Japonica hybrid should be trainned.
