Abstract:: Taking 10 processing tomato germplasm materials with good performance as materials，low temperature resistant germplasm materials were screened by using the natural low temperature and artificial cryogenic two treatments.The results showed that，from the low temperature stress of osmoregulation substance，morphological characteristics，spend deformity rate indexes in leaves，4 copies of materials (‘11- 922’，‘11- 283’，‘11- 652’，‘11- 450’) had a certain resistance to different low temperature；from the extreme low temperature stress in tomato plant morphological characteristics，material ‘11- 652’ had good resistance to low temperature performance，under low temperature 2～4℃ for 22 days，there were still 1 plant morphological characteristics was very good，it had excellent resistance to low temperature germplasm materials.
