Abstract:: Thirty different pepper resources were used as test materials，single index and comprehensive index determination methods were used，the effects of low temperature on the indexes of seed germination of different kinds of pepper resources were studied，in order to provide a reference for the identification and cultivation of low temperature resistance variety.The results showed that there were 8 cold resistant materials in 30 chili resources，7 low temperature sensitive materials，the rest were medium low temperature resistant materials.Different cold tolerance of seed germination stages of different pepper resources.There were significant differences in the 6 indexes of germination，relative germination，germination，relative germination，germination index and relative germination index.3-9，mixed pepper resources in greenhouse 71，3-10，62-6，12，mixed 2 single sword，No.58，980 ocean，K14 had strong low temperature resistance，the low temperature resistance of 37-77，70，D75，D78，23700，47 were poor.
