Abstract:: 9 new pepper varieties were used as materials，the growth index and physiological index of tolerance of low-temperature of 9 pepper varieties were evaluated with the methods of membership function.The tolerance of low-temperature of 9 peppers were studied and evaluated to offer reference for wintering cultivation in greenhouse.The results showed that the 9 pepper varieties were divided into 3 species groups with different tolerance of low-temperature.The first species group showed strong tolerance of low-temperature which included ‘1105’，‘1101’ and ‘1104’.The tolerance of low-temperature of second species group were moderate which included ‘1103’，‘Liangjian’and ‘Lyujian 65’.Tolerance of low-temperature of the third species group were the weakest which included ‘Red Rodin’，‘Audrey’ and ‘1102’.The ‘1105’ showed the strongest ability of tolerance of low-temperature，which grown winter greenhouse where mean temperature was below 10℃.The plant growth index and tolerance of low-temperature physiological indexes were better than other varieties.Membership function mean was 0.826.In general，‘1105’ showed a strong tolerance of low-temperature，had extended value for cultivation over wintering in greenhouse.
