Abstract：In order to establish the identification indexes and temperature conditions of pepper（Capsicum annuum L. ）chilling tolerance during seed germination stage，and to discuss the influence of low temperature on germination of different types of pepper varieties，this experiment took different pepper varieties as material，determined their germination percentage，germination potential，germination index and the relative value of these indicators under different temperature conditions. The results illustrated that relative germination index under 18 ℃，and relative germination percentage under 14 ℃ could be used as identification indexes for low temperature tolerance of pepper in seed germination；18 ℃ could be used as pressure condition to screen chilling tolerant varieties. The results also indicated that the seed of early-maturing varieties had better low temperature tolerance than that of medium maturing and medium late maturing varieties； the seeds of var. acuminatum Fingern had better low temperature tolerance；and the low temperature tolerance of var. grossum sent pepper seed was the weakest.
