6 nurseries of INGER (International network for genetic evaluation of rice) including IRBPHN, IRGMN, IRBN, IRBBN, IIRON and IRFAON were carried out in Guangdong Academy of Agricultural Sciences of South China from 2001-2005. 1778 rice germplasm resources of INGER were tested. Numbers of germplasm with good agronomic characters were evaluated and selected for rice breeding. Nine new varieties used 4 gerplasm resources of INGER with good commercial qualities, high yields and resistance were passed the evaluation and made registration in Guangdong province and their plant area was up to 250000ha. These varieties made a great economic contribution and ecological effective in rice yield and management of brown plant hopper, rice blast and rice bacterial in the province. About 200 resistant gerplasm of rice were restored in the Plant Protection Research Institute and about 5000 gerplasm of rice were stored in the rice gerplasm store of the Rice Research Institute, Guangdong Academy of Agricultural Sciences. The gerplasm of rice from INGER in Guangdong take an important contribution in raising the level of studies on resistance to insect pest and disease, rice breeding and gerplasm utilization.
