| Abstract: | Four special conventional rice varieties from different ecological zones in China, namely Fuhui838 (common indica), Yuelianggu (conventional indica landrace growing at high altitude in Yunnan), C418 (common japonica) and Lijing11 (conventional japonica landrace growing in high altitude with cold climate in Yunnan), were used to study the cold tolerance at reproductive stage under low temperature stress. At reproductive stage (meiosis and flowering), the plants were treated at 16℃ for 5 days and then they were set to recover for 5 days under control. The pollen fertility, seed-setting rate and 100-grain weight were then measured, and the differential expression of MADS-box genes in rice was studied by RT-PCR. Results showed: the cold tolerance ranking from lower to higher were: Fuhui838
